Parameters

result

A IAsyncResult object that holds the state information for the asynchronous operation. [Edit]

Returns

A int containing the number of bytes sent. [Edit]

Exceptions

Type	Reason
ArgumentNullException	asyncResult is null. [Edit]
ArgumentException	asyncResult was not returned by the current instance from a call to the Socket.SendTo(Byte[], int, int, SocketFlags, System.Net.EndPoint) method. [Edit]
InvalidOperationException	Socket.EndSendTo(IAsyncResult) was previously called for this operation. [Edit]
System.Net.Sockets.SocketException	Note: For additional information on causes of the SocketException, see the System.Net.Sockets.SocketException class. [Edit]
ObjectDisposedException	The current instance has been disposed. [Edit]

Remarks

This method blocks if the asynchronous operation has not completed.

The Socket.EndSendTo(IAsyncResult) method completes an asynchronous request that was started with a call to the Socket.BeginSendTo(Byte[], int, int, SocketFlags, System.Net.EndPoint, AsyncCallback, object) method. The object specified for the asyncResult parameter is required to be the same object as was returned by the Socket.BeginSendTo(Byte[], int, int, SocketFlags, System.Net.EndPoint, AsyncCallback, object) method call that began the request.

If the Socket.EndSendTo(IAsyncResult) method is invoked via the AsyncCallback delegate specified to the Socket.BeginSendTo(Byte[], int, int, SocketFlags, System.Net.EndPoint, AsyncCallback, object) method, the asyncResult parameter is the IAsyncResult argument passed to the delegate's method.

[Edit]

Example

For an outline of an asynchronous operation, see the Socket.BeginAccept(AsyncCallback, object) method. For the complete example, see the System.Net.Sockets.Socket class overview.
