Ends an asynchronous operation to determine whether a table exists.
Namespace: Microsoft.WindowsAzure.StorageClient
Assembly: Microsoft.WindowsAzure.StorageClient (in Microsoft.WindowsAzure.StorageClient.dll)
Usage
| Visual Basic |
|---|
Dim instance As CloudTableClient
Dim asyncResult As IAsyncResult
Dim returnValue As Boolean
returnValue = instance.EndDoesTableExist(asyncResult) |
Syntax
| Visual Basic |
|---|
Public Function EndDoesTableExist ( _
asyncResult As IAsyncResult _
) As Boolean |
| C# |
|---|
public bool EndDoesTableExist (
IAsyncResult asyncResult
) |
| C++ |
|---|
public:
bool EndDoesTableExist (
IAsyncResult^ asyncResult
) |
Parameters
- asyncResult
Type: System.IAsyncResult
An IAsyncResult that references the pending asynchronous operation.
Return Value
Type:
System.Booleantrue if table exists; otherwise,
false.
Example
The following code example checks whether a table exists asynchronously.
| C# |  Copy Code |
|---|
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.");
}
}
