Updated: April 24, 2013

[This topic is part of the Microsoft Azure Storage Client Library 1.7, which has been deprecated. See Storage Client Library for the latest version.]

Ends an asynchronous operation to determine whether a table exists.

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

'Kullanım
Dim instance As CloudTableClient
Dim asyncResult As IAsyncResult
Dim returnValue As Boolean

returnValue = instance.EndDoesTableExist(asyncResult)

public bool EndDoesTableExist (
	IAsyncResult asyncResult
)

Parameters

asyncResult

Type: System.IAsyncResult

An IAsyncResult that references the pending asynchronous operation.

Return Value

Type: System.Boolean

true if table exists; otherwise, false.

The following code example checks whether a table exists asynchronously.

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

    tableClient.BeginDoesTableExist("Products", CheckTableExistenceAsyncCallback, tableClient);
}

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

    if (tableClient.EndDoesTableExist(result))
    {
        Console.WriteLine("Table exists.");
    }
    else
    {
        Console.WriteLine("Table does not exist.");
    }
}
