C # Socket server client instance connection prototype

Server programs

Using System;
Using System. Net;
Using System. Net. Sockets;
Using System. Text;
Namespace SocketServer
{
/// <Summary>
/// Summary of Class1.
/// </Summary>
Class Class1

Web Client

Add a namespace:
Using System. Net;
Using System. Net. Sockets;
Using System. Text;

Connection code:
Private void socketButton_Click (object sender, System. EventArgs e)
{// Connect to the server program
Try
{
// Start the connection
TcpClient client = new TcpClient ("192.168.0.100", 81 );
NetworkStream ns = client. GetStream ();
Byte [] byteTime = Encoding. BigEndianUnicode. GetBytes ("client data submission \ n ");
Ns. Write (byteTime, 0, byteTime. Length );
// Return client information
Byte [] clientIp = Encoding. BigEndianUnicode. GetBytes ("Client IP Address:" + Request. UserHostAddress + "\ n ");
Ns. Write (clientIp, 0, clientIp. Length );
Byte [] bytes = new byte [1, 1024];
Int bytesRead = ns. Read (bytes, 0, bytes. Length );
ShowLabel. Text = "server return information" + Encoding. ASCII. GetString (bytes, 0, bytesRead );
Client. Close ();
}
Catch (Exception ex)
{
ShowLabel. Text = "throwing an exception" + ex. ToString ();
}
Finally {}
}
