c/s架构客户端和主控端的数据传输

Question

1、用SOCKET
2、用Remoting/WebService/WCF

Answer 1

客户端登陆的时候连接服务器，通讯直接用SOCKET就可以了啊。

Answer 2

using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Text;class MyTcpListener
{
    public static void Main()
    {
        TcpListener server = null;
        try
        {
            // Set the TcpListener on port 13000.
            Int32 port = 13000;
            IPAddress localAddr = IPAddress.Parse("127.0.0.1");            // TcpListener server = new TcpListener(port);
            server = new TcpListener(localAddr, port);            // Start listening for client requests.

                Console.WriteLine("Connected!");                data = null;                // Get a stream object for reading and writing
                NetworkStream stream = client.GetStream();                int i;                // Loop to receive all the data sent by the client.
                while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
                {
                    // Translate data bytes to a ASCII string.
                    data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
                    Console.WriteLine("Received: {0}", data);                    // Process the data sent by the client.
                    data = data.ToUpper();                    byte[] msg = System.Text.Encoding.ASCII.GetBytes(data);                    // Send back a response.
                    stream.Write(msg, 0, msg.Length);
                    Console.WriteLine("Sent: {0}", data);
                }                // Shutdown and end connection
                client.Close();
            }
        }
        catch (SocketException e)
        {
            Console.WriteLine("SocketException: {0}", e);
        }
        finally
        {
            // Stop listening for new clients.
            server.Stop();
        }
        Console.WriteLine("\nHit enter to continue...");
        Console.Read();
    }
}

Answer 4

类似QQ的话，研究下SOCKET 以后，还得研究一下路由器打洞。也就是简单的P2P。。GOOGLE一下，源码不少，看源码之前先消化理论。

Answer 5

P2P现在都是用的UPNP来映射固定的端口使其可以不同内网之间的通信的吧
