Stream.EndWrite Method

Ends an asynchronous write operation.

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

'Declaration
Public Overridable Sub EndWrite ( _
	asyncResult As IAsyncResult _
)
'Usage
Dim instance As Stream
Dim asyncResult As IAsyncResult

instance.EndWrite(asyncResult)
public void EndWrite (
	IAsyncResult asyncResult
)
public function EndWrite (
	asyncResult : IAsyncResult
)
Not applicable.

Parameters

asyncResult

A reference to the outstanding asynchronous I/O request.

Exception typeCondition

ArgumentNullException

asyncResult is a null reference (Nothing in Visual Basic).

ArgumentException

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

IOException

The stream is closed or an internal error has occurred.

For an example of creating a file and writing text to a file, see Writing Text to a File. For an example of reading text from a file, see Reading Text from a File. For an example of reading from and writing to a binary file, see Reading and Writing to a Newly Created Data File. For an example of asynchronous file I/O, see Asynchronous File I/O.

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.
