Even if you are developing an app that targets a single culture or region, you should use resource files to store strings and other resources that are displayed in the user interface. You should never add them directly to your code. Using resource files has a number of advantages:
- All the strings are in a single location. You don't have to search throughout your source code to identify strings to modify for a specific language or culture.
- There is no need to duplicate strings. Developers who don't use resource files often define the same string in multiple source code files. This duplication increases the probability that one or more instances will be overlooked when a string is modified.
- There's no need to duplicate strings. Developers who don't use resource files often define the same string in multiple source code files. This duplication increases the probability that one or more instances will be overlooked when a string is modified.
- You can include non-string resources, such as images or binary data, in the resource file instead of storing them in a separate standalone file, so they can be retrieved easily.
Using resource files has particular advantages if you are creating a localized app. When you deploy resources in satellite assemblies, the common language runtime automatically selects a culture-appropriate resource based on the user's current UI culture as defined by the <xref:System.Globalization.CultureInfo.CurrentUICulture%2A?displayProperty=nameWithType> property. As long as you provide an appropriate culture-specific resource and correctly instantiate a <xref:System.Resources.ResourceManager> object or use a strongly typed resource class, the runtime handles the details of retrieving the appropriate resources.
@ -155,9 +153,7 @@ You should never persist date and time data in a format that can vary by culture
You can avoid this problem in any of three ways:
- Serialize the date and time in binary format rather than as a string.
- Save and parse the string representation of the date and time by using a custom format string that is the same regardless of the user's culture.
- Save the string by using the formatting conventions of the invariant culture.
The following example illustrates the last approach. It uses the formatting conventions of the invariant culture returned by the static <xref:System.Globalization.CultureInfo.InvariantCulture%2A?displayProperty=nameWithType> property.

A date and time value can have multiple interpretations, ranging from a general time ("The stores open on January 2, 2013, at 9:00 A.M.") to a specific moment in time ("Date of birth: January 2, 2013 6:32:00 A.M."). When a time value represents a specific moment in time and you restore it from a serialized value, you should ensure that it represents the same moment in time regardless of the user's geographical location or time zone.
The following example illustrates this problem. It saves a single local date and time value as a string in three [standard formats](../../standard/base-types/standard-date-and-time-format-strings.md) ("G" for general date long time, "s" for sortable date/time, and "o" for round-trip date/time) as well as in binary format.

```
However, if you restore the data on a system in a different time zone, only the date and time value that was formatted with the "o" (round-trip) standard format string preserves time zone information and therefore represents the same instant in time. Here's the output when the date and time data is restored on a system in the Romance Standard Time zone:
```console
'3/30/2013 6:00:00 PM' --> 3/30/2013 6:00:00 PM Unspecified

'2023-03-30T18:00:00.0000000-07:00' --> 3/31/2023 3:00:00 AM Local
```
To accurately reflect a date and time value that represents a single moment of time regardless of the time zone of the system on which the data is deserialized, you can do any of the following:
- Save the value as a string by using the "o" (round-trip) standard format string. Then deserialize it on the target system.
- Convert it to UTC and save it as a string by using the "r" (RFC1123) standard format string. Then deserialize it on the target system and convert it to local time.
- Convert it to UTC and save it as a string by using the "u" (universal sortable) standard format string. Then deserialize it on the target system and convert it to local time.
- Convert it to UTC and save it in binary format. Then deserialize it on the target system and convert it to local time.
The following example illustrates each technique.

- The parameterless `ToString` method of any numeric type

The following example displays the average temperature per month in Paris, France. It first sets the current culture to French (France) before displaying the data, and then sets it to English (United States). In each case, the month names and temperatures are displayed in the format that is appropriate for that culture. Note that the two cultures use different decimal separators in the temperature value. Also note that the example uses the "MMMM" custom date and time format string to display the full month name, and that it allocates the appropriate amount of space for the month name in the result string by determining the length of the longest month name in the <xref:System.Globalization.DateTimeFormatInfo.MonthNames%2A?displayProperty=nameWithType> array.

Serializing currency values is a special case. Because a currency value depends on the unit of currency in which it is expressed; it makes little sense to treat it as an independent numeric value. However, if you save a currency value as a formatted string that includes a currency symbol, it cannot be deserialized on a system whose default culture uses a different currency symbol, as the following example shows.
