Ends an asynchronous write operation. (Consider using WriteAsync instead.)
public:
override void EndWrite(IAsyncResult ^ asyncResult);C#
public override void EndWrite(IAsyncResult asyncResult);override this.EndWrite : IAsyncResult -> unitPublic Overrides Sub EndWrite (asyncResult As IAsyncResult)- asyncResult
- IAsyncResult
A reference to the outstanding asynchronous I/O request.
asyncResult is null.
A handle to the pending write operation is not available.
-or-
The pending operation does not support writing.
asyncResult did not originate from a BeginWrite(Byte[], Int32, Int32, AsyncCallback, Object) method on the current stream.
The stream is closed or an internal error has occurred.
In .NET Framework 4 and earlier versions, you have to use methods such as BeginWrite and EndWrite to implement asynchronous I/O operations. These methods are still available in current versions to support legacy code; however, the new async methods, such as ReadAsync, WriteAsync, CopyToAsync, and FlushAsync, help you implement asynchronous I/O operations more easily.
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.
