控制台下的聊天程序

整理说明

1、学习c#时写的示例程序，没有什么价值。

2、使用的UDP协议。

示例代码

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.Threading;

namespace talk
{
    class Program
    {
       staticstring toanyone;
        staticvoid Main(string[] args)
        {
            Thread th =new Thread(new ThreadStart(ServerStart));
            th.Start();
            Console.WriteLine("----------欢迎使用聊天程序---------");
            Console.WriteLine("请输入对方ip:");
            
             toanyone = Console.ReadLine();
            do
            {
                Console.WriteLine("请输入您想说的话：");
                string msg = Console.ReadLine();
                if (msg.Trim().ToLower() =="exit")
                {
                    Console.WriteLine("退出聊天程序，欢迎再次使用！");
                    break;
                }
                else
                {
                    SendMessage(msg);
                }
            }
            while (true);
        }

        staticvoid SendMessage(string message)
        {
            UdpClient udpclient =new UdpClient(toanyone, 8090);
            byte[] bytes = Encoding.UTF8.GetBytes(message);
            udpclient.Send(bytes, bytes.Length);
            Console.WriteLine("您说："+ message +""+ DateTime.Now.ToString());
            Console.WriteLine("-------------------------------");
        }
        staticvoid ServerStart()
        {
            Console.WriteLine("-----------开始监听------------");
            UdpClient udplistener =new UdpClient(8090);
            IPEndPoint guest =new IPEndPoint(IPAddress.Any, 8090);
            while (true)
            {
                string Recevied ="";
                byte[] bytes = udplistener.Receive(ref guest);
                Recevied ="信息来自："+ guest.Address.ToString() +"说："+ Encoding.UTF8.GetString(bytes);
                Console.WriteLine(Recevied);
            }
        }
    }
}
