CloudTableClient.BeginDeleteTable Method

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 delete a table.

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

public IAsyncResult BeginDeleteTable (
	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 request.

The following code example deletes a table asynchronously.

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

  tableClient.BeginDeleteTable(
      "Categories", DeleteTableAsyncCallback, tableClient);            
}

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

    try
    {
        // End the operation.
        tableClient.EndDeleteTable(result);
    }
    catch (StorageClientException e)
    {
        Console.WriteLine("Error: {0}", e.Message);
        Console.WriteLine("Extended error info: {0} : {1}", 
            e.ExtendedErrorInformation.ErrorCode,
            e.ExtendedErrorInformation.ErrorMessage);
    } 
}


When a table is successfully deleted, it is immediately marked for deletion and is no longer accessible to clients. The table is later removed from the Table service during garbage collection.

Note that deleting a table is likely to take at least 40 seconds to complete. If an operation is attempted against the table while it was being deleted, a StorageClientException is thrown, with additional error information indicating that the table is being deleted.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
