I have developed server listening to multiple clients using asynchronous sockets. I have used the following method for stopping server from listening to clients.
//Button 2 -- To Stop Server
private void button2_Click(object sender, EventArgs e)
{
socket.Shutdown(SocketShutdown.Both);
socket.Disconnect(false);
socket.Close();
socket.Dispose();
}
But problem is that when I restart the server it shows error socket connection in use. So what is the proper way for closing sockets ans stopping server. I need to stop the server as soon as I press button in UI.
Finally I was able to solve my problem. Using the following code I was able to shutdown server cleanly : -
private void button2_Click(object sender, EventArgs e)
{
if (active_clients.Count >= 0)
{
// active client is the list of sockets clients were connected before
//server shutdown.
active_clients.ForEach(delegate(Socket s)
{
try
{
s.Shutdown(SocketShutdown.Both);
}
catch (ObjectDisposedException ex)
{
if (ex.InnerException is SocketException)
{
MessageBox.Show("some message");
return;
}
}
s.Close();
});
active_clients.Clear();
}
try
{
serverSocket.Close();
}
catch (Exception)
{
return;
}
}
If you want to shut down your server application you should also close all open client connections. These are not closed when you close the listening socket (that I assume is the variable socket
).
