.NET Framework Class Library
Stream..::.EndWrite Method

Ends an asynchronous write operation.

Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)
Syntax
Public Overridable Sub EndWrite ( _
	asyncResult As IAsyncResult _
)
public virtual void EndWrite(
	IAsyncResult asyncResult
)
public:
virtual void EndWrite(
	IAsyncResult^ asyncResult
)
abstract EndWrite : 
        asyncResult:IAsyncResult -> unit 
override EndWrite : 
        asyncResult:IAsyncResult -> unit 

Parameters

asyncResult
Type: System..::.IAsyncResult
A reference to the outstanding asynchronous I/O request.
Exceptions
ExceptionCondition
ArgumentNullException

asyncResult is nullNothingnullptra 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.

Remarks

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.
