DeflateStream.EndWrite(IAsyncResult) Method


Ends an asynchronous write operation. (Consider using the WriteAsync(Byte[], Int32, Int32) method instead.)

 override void EndWrite(IAsyncResult ^ asyncResult);
 override void EndWrite(IAsyncResult ^ async_result);
public override void EndWrite (IAsyncResult asyncResult);
public override void EndWrite (IAsyncResult async_result);
override this.EndWrite : IAsyncResult -> unit
override this.EndWrite : IAsyncResult -> unit
Public Overrides Sub EndWrite (asyncResult As IAsyncResult)
Public Overrides Sub EndWrite (async_result As IAsyncResult)



A reference to the outstanding asynchronous I/O request.


asyncResult is null.

asyncResult did not originate from a BeginWrite(Byte[], Int32, Int32, AsyncCallback, Object) method on the current stream.

An exception was thrown during a call to WaitOne().

The stream is null.


The end write call is invalid.


Starting with the .NET Framework 4.5, you can perform asynchronous write operations by using the WriteAsync method. The EndWrite method is still available in the .NET Framework 4.5 to support legacy code; however, you can implement asynchronous I/O operations more easily by using the new async methods. For more information, see Asynchronous File I/O.

EndWrite must be called only once for every call to the BeginWrite method.

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.
