Microsoft Azure Cosmos DB .NET SDK Version 3

This client library enables client applications to connect to Azure Cosmos DB for NoSQL. Azure Cosmos DB is a globally distributed, multi-model database service. For more information, refer to https://azure.microsoft.com/services/cosmos-db/.

CosmosClient client = new CosmosClient("https://mycosmosaccount.documents.azure.com:443/", "mysupersecretkey");
Database database = await client.CreateDatabaseIfNotExistsAsync("MyDatabaseName");
Container container = await database.CreateContainerIfNotExistsAsync(
    "MyContainerName",
    "/partitionKeyPath",
    400);

// Create an item
dynamic testItem = new { id = "MyTestItemId", partitionKeyPath = "MyTestPkValue", details = "it's working", status = "done" };
ItemResponse<dynamic> createResponse = await container.CreateItemAsync(testItem);

// Query for an item
using (FeedIterator<dynamic> feedIterator = container.GetItemQueryIterator<dynamic>(
    "select * from T where T.status = 'done'"))
{
    while (feedIterator.HasMoreResults)
    {
        FeedResponse<dynamic> response = await feedIterator.ReadNextAsync();
        foreach (var item in response)
        {
            Console.WriteLine(item);
        }
    }
}
