네임스페이스: Microsoft.WindowsAzure.StorageClient
어셈블리: Microsoft.WindowsAzure.StorageClient(microsoft.windowsazure.storageclient.dll)

사용법

‘사용 방법
Dim instance As CloudTableClient
Dim tableName As String
Dim callback As AsyncCallback
Dim state As Object
Dim returnValue As IAsyncResult

returnValue = instance.BeginDeleteTableIfExist(tableName, callback, state)

구문

C++

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

public IAsyncResult BeginDeleteTableIfExist (
	String tableName, 
	AsyncCallback callback, 
	Object state
)

JScript

public function BeginDeleteTableIfExist (
	tableName : String, 
	callback : AsyncCallback, 
	state : Object
) : IAsyncResult

매개 변수

tableName: The table name.

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

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

반환 값

An IAsyncResult that references the asynchronous operation.

예제

The following code example deletes a table asynchronously if it exists.

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

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

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

    // End the operation.
    if (tableClient.EndDeleteTableIfExist(result))
    {
        Console.WriteLine("Table deleted.");
    }
    else
    {
        Console.WriteLine("Table does not exist and so could not be deleted.");
    }
}

설명

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.
