Client- Sever,

[makiavelli]

Client- Sever Application, brauche dringend Hilfe!

Hallo, ich muss eine Client-Server Application herstellen unzwar einen virtueller Shop. Ich kriege es aber nicht hin die Information von Server zu Client zu ubertragen. Ich mochte das der Client die Informationen uber die Produkte sehen kann( die Funktion anzeigen aus der server Class) und dass der Client die Operation fur Kaufen( Funktion operation_durchfueren aus server class machen soll)

Hier ist sind die Quell-Datein

using System;
using System.IO;
using System.Net;
using System.Text;
using System.Net.Sockets;
using System.Collections;



public class clnt {
	
	public static void Main() {
		
		try {
			TcpClient tcpclnt = new TcpClient();
			StreamReader ttt= new StreamReader ( new FileStream ( "c:\\password.txt", System.IO.FileMode.Open ) );
			string line= ttt.ReadToEnd();
			Console.WriteLine(line);Console.WriteLine("Connecting.....");
			Console.WriteLine(line.Length);
			Console.WriteLine("enter password");
			string parola= Console.In.ReadLine ();
			int i =line.IndexOf(parola, 0, line.Length);
			
			if (i >0)
			
			{
				//bool zzz = true;
				tcpclnt.Connect("192.168.0.7",8001); // use the ipaddress as in the server program
				Console.WriteLine("Connected");
				Stream stm = tcpclnt.GetStream();
				byte[] bb=new byte[100];
				int k=stm.Read(bb,0,100);
			
				for (int j=0;j<k;j++)
					Console.Write(Convert.ToChar(bb[i]));
				tcpclnt.Close();}
			else
				Console.WriteLine("Parola gresita");
				tcpclnt.Close();
				//break; 
			
		}
		
		catch (Exception e) {
			Console.WriteLine("Error..... " + e.StackTrace);
		}
	}

}
