FtpWebRequest.EndGetRequestStream Method

Ends a pending asynchronous operation started with BeginGetRequestStream.

Namespace:  System.Net
Assembly:  System (in System.dll)

abstract EndGetRequestStream : 
        asyncResult:IAsyncResult -> Stream  
override EndGetRequestStream : 
        asyncResult:IAsyncResult -> Stream

Parameters

asyncResult
Type: System.IAsyncResult

The IAsyncResult object that was returned when the operation started.

Return Value

Type: System.IO.Stream
A writable Stream instance associated with this instance.

ExceptionCondition
ArgumentNullException

asyncResult is a null reference (Nothing in Visual Basic).

ArgumentException

asyncResult was not obtained by calling BeginGetRequestStream.

InvalidOperationException

This method was already called for the operation identified by asyncResult.

If the operation has not completed, the EndGetRequestStream method blocks until the operation completes. To determine whether the operation has completed, check the IsCompleted property before calling EndGetRequestStream.

In addition to the exceptions noted in "Exceptions," EndGetRequestStream rethrows exceptions that were thrown while opening the stream for writing.
