EndWrite Method

Stream.EndWrite Method

Ends an asynchronous write operation.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

public virtual void EndWrite(
	IAsyncResult asyncResult


Type: System.IAsyncResult
A reference to the outstanding asynchronous I/O request.


asyncResult is null.


asyncResult did not originate from a BeginWrite method on the current stream.


The stream is closed or an internal error has occurred.

EndWrite must be called exactly once on every IAsyncResult from BeginWrite.

This method blocks until the I/O operation has completed. Errors that occur during an asynchronous write request, such as a disk failure during the I/O request, occur on the thread pool thread and become visible upon a call to EndWrite. Exceptions thrown by the thread pool thread will not be visible when calling EndWrite.
