Stream::EndWrite Method (IAsyncResult^)
Ends an asynchronous write operation. (Consider using WriteAsync instead; see the Remarks section.)
Assembly: mscorlib (in mscorlib.dll)
asyncResult is null.
A handle to the pending write operation is not available.
The pending operation does not support writing.
asyncResult did not originate from a BeginWrite method on the current stream.
The stream is closed or an internal error has occurred.
In the .NET Framework 4 and earlier versions, you have to use methods such as BeginWrite and to implement asynchronous I/O operations. These methods are still available in the .NET Framework 4.5 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.
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.
