Updated: April 24, 2013

[This topic is part of the Windows Azure Storage Client Library 1.7, which has been deprecated. The current recommended version is Storage Client Library 3.0.]

Begins an asynchronous operation to create a table with the specified name if it does not already exist.

Namespace: Microsoft.WindowsAzure.StorageClient
Assembly: Microsoft.WindowsAzure.StorageClient (in Microsoft.WindowsAzure.StorageClient.dll)
'Utilisation

public IAsyncResult BeginCreateTableIfNotExist (
	string tableName,
	AsyncCallback callback,
	Object state
)

Parameters

tableName

Type: System.String

The table name.

callback

Type: System.AsyncCallback

The callback delegate that will receive notification when the asynchronous operation completes.

state

Type: System.Object

A user-defined object that will be passed to the callback delegate.

Return Value

Type: System.IAsyncResult

An IAsyncResult that references the asynchronous operation.

The following code example creates a table asynchronously if it does not exist.

static void CreateTableIfNotExistsAsync(CloudStorageAccount storageAccount)
{
  // Create service client for credentialed access to the Table service.
  CloudTableClient tableClient = 
      new CloudTableClient(
            storageAccount.TableEndpoint.ToString(),
            storageAccount.Credentials);

    // Begin the operation to create a new table.
    tableClient.BeginCreateTableIfNotExist(
         "Categories", CreateTableIfNotExistsAsyncCallback, tableClient);
}

public static void CreateTableIfNotExistsAsyncCallback(IAsyncResult result)
{
    CloudTableClient tableClient = (CloudTableClient)result.AsyncState;

    // End the operation.
    if (tableClient.EndCreateTableIfNotExist(result))
    {
        Console.WriteLine("Table created."); 
    }
}

For guidance about valid table names, see the "Table Names" section in Understanding the Table Service Data Model.
