public override Stream EndGetRequestStream(
	IAsyncResult asyncResult
)

Parameters

Type: System.IAsyncResult
The pending request for a stream.

Return Value

Type: System.IO.Stream
A Stream to use to write request data.

The request did not complete, and no stream is available.

ArgumentException

asyncResult was not returned by the current instance from a call to BeginGetRequestStream.

The EndGetRequestStream method completes an asynchronous request for a stream that was started by the BeginGetRequestStream method. After the Stream object has been returned, you can send data with the HttpWebRequest by using the Stream.Write method.

Caution noteCaution:

You must call the Stream.Close method to close the stream and release the connection for reuse. Failure to close the stream causes your application to run out of connections.
