3.0 UDP Client & Server messaging in C# & VB.NET

UDP, or the User Datagram Protocol is a low-latency, high performance protocol which runs over IP. It is ideal for applications where performance is more important than quality or integrity. Therefore it is excellent for Internet Radio, but not good for secure file transfer applications.

This C# (and VB.NET) program can be used to send simple messages from computer to computer, using the high performance UDP protocol. To use this program, run the server program on one computer, note the IP address of this computer by typing the number written on-screen. Install the client on a separate computer, type in the server IP address, and a message to send in the box provided, and press send. You should see the message appear on the server computer.
