title: C# TCP/IP server and client
body: <p>i have a simple TCP client/server application.  How do set up the two program so on the server side it requires a username and a password, and when the client tries to connect, they have to enter the correct user name and password and send it to the server side, the server side will check to see if thats the correct username and password, if its correct then it allows connection, otherwise it rejects the connction</p>
