Handles the end of an asynchronous write operation. (Consider using the Stream.WriteAsync method instead; see the Remarks section.)
Assembly: System (in System.dll)
The underlying stream is null.
The underlying stream is closed.
Starting with the .NET Framework 4.5, you can perform asynchronous write operations by using the Stream.WriteAsync method. The method is still available in .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.
The method completes the asynchronous write operation started in the BeginWrite method.
Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
