DeflateStream.EndWrite Method

Ends an asynchronous write operation. (Consider using the Stream.WriteAsync method instead; see the Remarks section.)

Namespace:  System.IO.Compression
Assembly:  System (in System.dll)

public override void EndWrite(
	IAsyncResult asyncResult
)

Parameters

asyncResult
Type: System.IAsyncResult

A reference to the outstanding asynchronous I/O request.

ExceptionCondition
ArgumentNullException

asyncResult is null.

ArgumentException

asyncResult did not originate from a BeginWrite method on the current stream.

Exception

An exception was thrown during a call to WaitOne.

InvalidOperationException

The stream is null.

InvalidOperationException

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.
