This is a class I've used on a network chat program I built.


Provides client connections for TCP network services.

public class TcpClient : IDisposable

The following code example establishes a TcpClient connection.

static void Connect(String server, String message)
    // Create a TcpClient.
    // Note, for this client to work you need to have a TcpServer
    // connected to the same address as specified by the server, port
    // combination.
    Int32 port = 13000;
    TcpClient client = new TcpClient(server, port);

    // Translate the passed message into ASCII and store it as a Byte array.
    Byte[] data = System.Text.Encoding.ASCII.GetBytes(message);

    // Get a client stream for reading and writing.
   //  Stream stream = client.GetStream();

    NetworkStream stream = client.GetStream();

    // Send the message to the connected TcpServer.
    stream.Write(data, 0, data.Length);

    Console.WriteLine("Sent: {0}", message);

    // Receive the TcpServer.response.

    // Buffer to store the response bytes.
    data = new Byte[256];

    // String to store the response ASCII representation.
    String responseData = String.Empty;

    // Read the first batch of the TcpServer response bytes.
    Int32 bytes = stream.Read(data, 0, data.Length);
    responseData = System.Text.Encoding.ASCII.GetString(data, 0, bytes);
    Console.WriteLine("Received: {0}", responseData);

    // Close everything.
  catch (ArgumentNullException e)
    Console.WriteLine("ArgumentNullException: {0}", e);
  catch (SocketException e)
    Console.WriteLine("SocketException: {0}", e);

  Console.WriteLine("\n Press Enter to continue...");
