EndReceive() public méthode

Ends a pending asynchronous receive.
EndReceive is a blocking method that completes the asynchronous receive operation started in the BytesRoad.Net.Sockets.SocketEx.BeginReceive method. The EndReceive method will read as much data as is available up to the number of bytes you specified in the size parameter of the BytesRoad.Net.Sockets.SocketEx.BeginReceive method. If the remote host shuts down the BytesRoad.Net.Sockets.SocketEx connection with the BytesRoad.Net.Sockets.SocketEx.Shutdown method, and all available data has been received, the EndReceive method will complete immediately and return zero bytes.
