override System::Threading::Tasks::Task<System::IO::Stream ^> ^ GetRequestStreamAsync();
public override System.Threading.Tasks.Task<System.IO.Stream> GetRequestStreamAsync ();
override this.GetRequestStreamAsync : unit -> System.Threading.Tasks.Task<System.IO.Stream>
Public Overrides Function GetRequestStreamAsync () As Task(Of Stream)
Returns
The task object representing the asynchronous operation.
Exceptions
The stream is being used by a previous call to BeginGetRequestStream(AsyncCallback, Object).
-or-
The stream already received a response previous to your request.
The Method property is GET or HEAD.

Remarks
Note
In the case of asynchronous requests, the client application is responsible for implementing its own time-out mechanism.
This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by GetRequestStream().
