# Controlling Serialization and Deserialization with SerializationBinder

> [!WARNING]
|
||||
> <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter> is not secure and can ***not*** be made secure. For more information, see the [BinaryFormatter security guide](../../../standard/serialization/binaryformatter-security-guide.md).
|
||||
|
||||
During serialization, a formatter transmits the information required to create an instance of an object of the correct type and version. This information generally includes the full type name and assembly name of the object. By default, deserialization uses this information to create an instance of an identical object. Some users may need to control which class to serialize and deserialize, either because the original class may not exist on the machine performing deserialization, the original class has moved between assemblies, or a different version of the class is required on the server and client. For more information, see [Usage of Serialization Binder](../samples/usage-of-serialization-binder.md).
|
||||
|
||||
> [!WARNING]
|
||||
> This functionality is only available when using the <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter> or the <xref:System.Runtime.Serialization.NetDataContractSerializer>.
|
||||
|
||||
## Using SerializationBinder
|
||||
|
||||
<xref:System.Runtime.Serialization.SerializationBinder> is an abstract class used to control the actual types used during serialization and deserialization. To control the types used during serialization and deserialization, derive a class from <xref:System.Runtime.Serialization.SerializationBinder> and override the <xref:System.Runtime.Serialization.SerializationBinder.BindToName(System.Type,System.String@,System.String@)> and <xref:System.Runtime.Serialization.SerializationBinder.BindToType(System.String,System.String)> methods. The <xref:System.Runtime.Serialization.SerializationBinder.BindToName(System.Type,System.String@,System.String@)> method takes a <xref:System.Type> and returns an assembly and type name. The <xref:System.Runtime.Serialization.SerializationBinder.BindToType(System.String,System.String)> method takes an assembly and type name and returns a <xref:System.Type>.

This is useful when using types for .NET Framework remoting.

# Usage of Serialization Binder
|

## Discussion
|
||||
|
||||
This sample shows how two entities that are targeting different versions of the .NET Framework can communicate using the binary formatter and the serialization binder.
|
||||
|
||||
This sample was developed using .NET Remoting. It consists of a server targeting .NET Framework 4, which implements a contract with generic types, and two different clients, one targeting .NET Framework 2.0 and another targeting .NET Framework 4.
|
||||
|
||||
The server attaches a <xref:System.Runtime.Serialization.SerializationBinder> to the binary formatter to be able to change the version of the types accordingly on serialization, so both clients can deserialize those types properly.
|
||||
|
||||
#### To set up, build and run the sample
|
||||
|
||||
1. To execute the client, right-click the solution, SBGenericsVTS (6 projects) and then select **Properties**.
|
||||
|
||||
2. In **Common Properties**, select **Startup Project**, then select **Multiple Startup Projects**.
|
||||
|
||||
3. Select **Server** first, then **Client20** and then **Client40**. Select the **Start** action to these three projects and leave the rest set to **None**.
|
||||
|
||||
4. Click **OK** and then press <kbd>F5</kbd> to run the sample.

### Control Flow
|
||||
|
||||
Just as in any programming language, WF provides support for control flows for workflow definitions by introducing a set of control flow activities for sequencing, looping, branching and other patterns. In WF3, when the same activity needs to be re-executed, a new <xref:System.Workflow.ComponentModel.ActivityExecutionContext> is created and the activity is cloned through a heavy-weight serialization and deserialization logic based on <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter>. Usually the performance for iterative control flows is much slower than executing a sequence of activities.

WF4 handles this quite differently. It takes the activity template, creates a new ActivityInstance object, and adds it to the scheduler queue. This whole process only involves explicit object creation and is very lightweight.

Orleans supports transmission of arbitrary types at runtime and therefore the in-built code generator cannot determine the entire set of types that will be transmitted ahead of time. Additionally, certain types cannot have serializers generated for them because they are inaccessible (for example, `private`) or have inaccessible fields (for example, `readonly`). Therefore, there is a need for just-in-time serialization of types that were unexpected or could not have serializers generated ahead of time. The serializer responsible for these types is called the *fallback serializer*. Orleans ships with two fallback serializers:
|
||||
|
||||
* <xref:Orleans.Serialization.BinaryFormatterSerializer?displayProperty=fullName> which uses .NET's <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter>; and
|
||||
* <xref:Orleans.Serialization.ILBasedSerializer?displayProperty=fullName> which emits [CIL](../../../standard/glossary.md#il) instructions at runtime to create serializers that leverage Orleans' serialization framework to serialize each field. This means that if an inaccessible type `MyPrivateType` contains a field `MyType` which has a custom serializer, that custom serializer will be used to serialize it.
|
||||
* <xref:Orleans.Serialization.BinaryFormatterSerializer?displayProperty=fullName>, which uses .NET's <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter>; and
|

This means that if an inaccessible type `MyPrivateType` contains a field `MyType` which has a custom serializer, that custom serializer will be used to serialize it.
|
||||
|
||||
The fallback serializer can be configured using the <xref:Orleans.Configuration.SerializationProviderOptions.FallbackSerializationProvider> property on both <xref:Orleans.Runtime.Configuration.ClientConfiguration> on the client and <xref:Orleans.Runtime.Configuration.GlobalConfiguration> on the silos.

# How to determine if a .NET Standard object is binary serializable
|
||||
|
||||
.NET Standard is a specification that defines the types and members that must be present on specific .NET implementations that conform to that version of the standard. However, .NET Standard does not define whether a type is serializable. The types defined in the .NET Standard Library are not marked with the <xref:System.SerializableAttribute> attribute. Instead, specific .NET implementations, such as .NET Framework and .NET Core, are free to determine whether a particular type is binary serializable.
|
||||
|
||||
If you've developed a library that targets .NET Standard, your library can be consumed by any .NET implementation that supports .NET Standard. This means that you cannot know in advance whether a particular type is binary serializable; you can only determine that at run time.
|
||||
|
||||
You can determine whether an object is binary serializable at run time by retrieving the value of the <xref:System.Type.IsSerializable> property of a <xref:System.Type> object that represents that object's type. The following example provides one implementation. It defines an `IsSerializable(Object)` extension method that indicates whether any <xref:System.Object> instance can be binary serialized.
|
||||
|
||||
[!code-csharp[is-a-type-serializable](~/samples/snippets/standard/serialization/is-serializable/csharp/program.cs#2)]
|
||||
[!code-vb[is-a-type-serializable](~/samples/snippets/standard/serialization/is-serializable/vb/library.vb#2)]
|
||||
|
||||
You can then pass any object to the method to determine whether it can be binary serialized and deserialized on the current .NET implementation, as the following example shows:

||||
|
||||
[!code-csharp[test-is-a-type-serializable](~/samples/snippets/standard/serialization/is-serializable/csharp/program.cs#1)]

# Walkthrough: Persisting an Object in Visual Studio (Visual Basic)
|
||||
|
||||
Although you can set an object's properties to default values at design time, any values entered at run time are lost when the object is destroyed. You can use serialization to persist an object's data between instances, which enables you to store values and retrieve them the next time that the object is instantiated.
|
||||
|
||||
> [!NOTE]
|
||||
> In Visual Basic, to store simple data, such as a name or number, you can use the `My.Settings` object. For more information, see [My.Settings Object](../../../language-reference/objects/my-settings-object.md).
|
||||
|
||||
In this walkthrough, you will create a simple `Loan` object and persist its data to a file. You will then retrieve the data from the file when you re-create the object.
|
||||
|
||||
> [!IMPORTANT]
|
||||
> This example creates a new file, if the file does not already exist. If an application must create a file, that application must `Create` permission for the folder. Permissions are set by using access control lists. If the file already exists, the application needs only `Write` permission, a lesser permission. Where possible, it is more secure to create the file during deployment, and only grant `Read` permissions to a single file (instead of Create permissions for a folder). Also, it is more secure to write data to user folders than to the root folder or the Program Files folder.
|
||||
|
||||
> [!IMPORTANT]
|
||||
> This example stores data in a binary. These formats should not be used for sensitive data, such as passwords or credit-card information.

|
||||
|
||||
## Creating the Loan Object
|
||||
|
||||
The first step is to create a `Loan` class and a test application that uses the class.
|
||||
|
||||
### To create the Loan class
|
||||
|
||||
1. Create a new Class Library project and name it "LoanClass". For more information, see [Creating Solutions and Projects](/visualstudio/ide/creating-solutions-and-projects).
|
||||
|
||||
2. In **Solution Explorer**, open the shortcut menu for the Class1 file and choose **Rename**. Rename the file to `Loan` and press ENTER. Renaming the file will also rename the class to `Loan`.
|
||||
|
||||
3. Add the following public members to the class:
|
||||
|
||||
```vb
|
||||
Public Class Loan
|
||||
Implements System.ComponentModel.INotifyPropertyChanged
|
||||
|
||||
Public Property LoanAmount As Double
|
||||
Public Property InterestRate As Double
|
||||
Public Property Term As Integer
|
||||
|
||||
Private p_Customer As String
|
||||
Public Property Customer As String
|
||||
Get
|
||||
Return p_Customer
|
||||
End Get
|
||||
Set(ByVal value As String)
|
||||
p_Customer = value
|
||||
RaiseEvent PropertyChanged(Me,
|
||||
New System.ComponentModel.PropertyChangedEventArgs("Customer"))
|
||||
End Set
|
||||
End Property
|
||||
|
||||
Event PropertyChanged As System.ComponentModel.PropertyChangedEventHandler _
|
||||
Implements System.ComponentModel.INotifyPropertyChanged.PropertyChanged
|
||||
|
||||
Public Sub New(ByVal loanAmount As Double,
|
||||
ByVal interestRate As Double,
|
||||
ByVal term As Integer,
|
||||
ByVal customer As String)
|
||||
|
||||
Me.LoanAmount = loanAmount
|
||||
Me.InterestRate = interestRate
|
||||
Me.Term = term
|
||||
p_Customer = customer
|
||||
End Sub
|
||||
End Class
|
||||
```
|
||||
|
||||
You will also have to create a simple application that uses the `Loan` class.
|
||||
|
||||
### To create a test application
|
||||
|
||||
1. To add a Windows Forms Application project to your solution, on the **File** menu, choose **Add**,**New Project**.
|
||||
|
||||
2. In the **Add New Project** dialog box, choose **Windows Forms Application**, and enter `LoanApp` as the name of the project, and then click **OK** to close the dialog box.
|
||||
|
||||
3. In **Solution Explorer**, choose the LoanApp project.
|
||||
|
||||
4. On the **Project** menu, choose **Set as StartUp Project**.
|
||||
|
||||
5. On the **Project** menu, choose **Add Reference**.
|
||||
|
||||
6. In the **Add Reference** dialog box, choose the **Projects** tab and then choose the LoanClass project.
|
||||
|
||||
7. Click **OK** to close the dialog box.
|
||||
|
||||
8. In the designer, add four <xref:System.Windows.Forms.TextBox> controls to the form.
|
||||
|
||||
9. In the Code Editor, add the following code:
|
||||
|
||||
```vb
|
||||
Private WithEvents TestLoan As New LoanClass.Loan(10000.0, 0.075, 36, "Neil Black")
|
||||
|
||||
Private Sub Form1_Load() Handles MyBase.Load
|
||||
TextBox1.Text = TestLoan.LoanAmount.ToString
|
||||
TextBox2.Text = TestLoan.InterestRate.ToString
|
||||
TextBox3.Text = TestLoan.Term.ToString
|
||||
TextBox4.Text = TestLoan.Customer
|
||||
End Sub
|
||||
```
|
||||
|
||||
10. Add an event handler for the `PropertyChanged` event to the form by using the following code:
|
||||
|
||||
```vb
|
||||
Public Sub CustomerPropertyChanged(
|
||||
ByVal sender As Object,
|
||||
ByVal e As System.ComponentModel.PropertyChangedEventArgs
|
||||
) Handles TestLoan.PropertyChanged
|
||||
|
||||
MsgBox(e.PropertyName & " has been changed.")
|
||||
End Sub
|
||||
```
|
||||
|
||||
At this point, you can build and run the application. Note that the default values from the `Loan` class appear in the text boxes. Try to change the interest-rate value from 7.5 to 7.1, and then close the application and run it again—the value reverts to the default of 7.5.
|
||||
|
||||
In the real world, interest rates change periodically, but not necessarily every time that the application is run. Rather than making the user update the interest rate every time that the application runs, it is better to preserve the most recent interest rate between instances of the application. In the next step, you will do just that by adding serialization to the Loan class.
|
||||
|
||||
## Using Serialization to Persist the Object
|
||||
|
||||
In order to persist the values for the Loan class, you must first mark the class with the `Serializable` attribute.
|
||||
|
||||
### To mark a class as serializable
|
||||
|
||||
- Change the class declaration for the Loan class as follows:
|
||||
|
||||
```vb
|
||||
<Serializable()>
|
||||
Public Class Loan
|
||||
```
|
||||
|
||||
The `Serializable` attribute tells the compiler that everything in the class can be persisted to a file. Because the `PropertyChanged` event is handled by a Windows Form object, it cannot be serialized. The `NonSerialized` attribute can be used to mark class members that should not be persisted.
|
||||
|
||||
### To prevent a member from being serialized
|
||||
|
||||
- Change the declaration for the `PropertyChanged` event as follows:
|
||||
|
||||
```vb
|
||||
<NonSerialized()>
|
||||
Event PropertyChanged As System.ComponentModel.PropertyChangedEventHandler _
|
||||
Implements System.ComponentModel.INotifyPropertyChanged.PropertyChanged
|
||||
```
|
||||
|
||||
The next step is to add the serialization code to the LoanApp application. In order to serialize the class and write it to a file, you will use the <xref:System.IO> and <xref:System.Xml.Serialization> namespaces. To avoid typing the fully qualified names, you can add references to the necessary class libraries.
|
||||
|
||||
### To add references to namespaces
|
||||
|
||||
- Add the following statements to the top of the `Form1` class:
|
||||
|
||||
```vb
|
||||
Imports System.IO
|
||||
Imports System.Runtime.Serialization.Formatters.Binary
|
||||
```
|
||||
|
||||
In this case, you are using a binary formatter to save the object in a binary format.
|
||||
|
||||
The next step is to add code to deserialize the object from the file when the object is created.
|
||||
|
||||
### To deserialize an object
|
||||
|
||||
1. Add a constant to the class for the serialized data's file name.
|
||||
|
||||
```vb
|
||||
Const FileName As String = "..\..\SavedLoan.bin"
|
||||
```
|
||||
|
||||
2. Modify the code in the `Form1_Load` event procedure as follows:
|
||||
|
||||
```vb
|
||||
Private WithEvents TestLoan As New LoanClass.Loan(10000.0, 0.075, 36, "Neil Black")
|
||||
|
||||
Private Sub Form1_Load() Handles MyBase.Load
|
||||
If File.Exists(FileName) Then
|
||||
Dim TestFileStream As Stream = File.OpenRead(FileName)
|
||||
Dim deserializer As New BinaryFormatter
|
||||
TestLoan = CType(deserializer.Deserialize(TestFileStream), LoanClass.Loan)
|
||||
TestFileStream.Close()
|
||||
End If
|
||||
|
||||
AddHandler TestLoan.PropertyChanged, AddressOf Me.CustomerPropertyChanged
|
||||
|
||||
TextBox1.Text = TestLoan.LoanAmount.ToString
|
||||
TextBox2.Text = TestLoan.InterestRate.ToString
|
||||
TextBox3.Text = TestLoan.Term.ToString
|
||||
TextBox4.Text = TestLoan.Customer
|
||||
End Sub
|
||||
```
|
||||
|
||||
Note that you first must check that the file exists. If it exists, create a <xref:System.IO.Stream> class to read the binary file and a <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter> class to translate the file. You also need to convert from the stream type to the Loan object type.
|
||||
|
||||
Next you must add code to save the data entered in the text boxes to the `Loan` class, and then you must serialize the class to a file.
|
||||
|
||||
### To save the data and serialize the class
|
||||
|
||||
- Add the following code to the `Form1_FormClosing` event procedure:
|
||||
|
||||
```vb
|
||||
Private Sub Form1_FormClosing() Handles MyBase.FormClosing
|
||||
TestLoan.LoanAmount = CDbl(TextBox1.Text)
|
||||
TestLoan.InterestRate = CDbl(TextBox2.Text)
|
||||
TestLoan.Term = CInt(TextBox3.Text)
|
||||
TestLoan.Customer = TextBox4.Text
|
||||
|
||||
Dim TestFileStream As Stream = File.Create(FileName)
|
||||
Dim serializer As New BinaryFormatter
|
||||
serializer.Serialize(TestFileStream, TestLoan)
|
||||
TestFileStream.Close()
|
||||
End Sub
|
||||
```
|
||||
|
||||
At this point, you can again build and run the application. Initially, the default values appear in the text boxes. Try to change the values and enter a name in the fourth text box. Close the application and then run it again. Note that the new values now appear in the text boxes.

As of .NET Framework 4.5, a number of <xref:System.Xml.Serialization.XmlSerializer?displayProperty=fullName> changes may cause differences in deserialization when using <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter?displayProperty=fullName> to deserialize types that had been loaded in the LoadFrom context.
