TCP Programming

A TCP/IP connection is the right choice when you need a reliable two-way, connection-based communication that ensures that data packets will be received in the correct order and that no data  will be lost or transferred multiple times. You can create a TCP/IP socket with the following code:

Socket socket = new Socket(Addressfamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);

Connecting to a Server as a Client

After you have created a socket object, you are able to initiate a connection to a (remote) server with the Connect method of your socket. Your .NET Micro Framework application is thereby  the client application. The connection establishment takes place synchronously, so your client application will be blocked until a connection is available.

public void Connect(EndPoint remoteEP);

Take note of the remoteEP parameter of the abstract type System.Net.EndPoint in the signature of the Connect method. For IP connections, you need to pass an instance of the System.Net.IPEndPoint class to the Connect method. IPEndPoint contains the IP address and the communication port, and it is derived from EndPoint.

You can create an IPEndPoint object with one of the following two constructors:
public IPEndPoint(long address, int port)
public IPEndPoint(IPAddress address, int port)
