Ends an asynchronous write operation. (Consider using Stream.WriteAsync(Byte[], int, int) instead; see the Remarks section.)
Syntax
Parameters
- asyncResult
Exceptions
Type Reason ArgumentNullException The asyncResult parameter is null. ArgumentException asyncResult did not originate from a Stream.BeginWrite(Byte[], int, int, AsyncCallback, object) method on the current stream.
Remarks
In the .NET Framework 4 and earlier versions, you have to use methods such as Stream.BeginWrite(Byte[], int, int, AsyncCallback, object) and Stream.EndWrite(IAsyncResult) to implement asynchronous I/O operations. These methods are still available in the net_v45 to support legacy code; however, the new async methods, such as Stream.ReadAsync(Byte[], int, int), Stream.WriteAsync(Byte[], int, int), Stream.CopyToAsync(Stream), and Stream.FlushAsync, help you implement asynchronous I/O operations more easily.
EndWrite must be called exactly once on every IAsyncResult from Stream.BeginWrite(Byte[], int, int, AsyncCallback, object).
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.
