首先创建一个C# 控制台应用程序, 直接服务器端代码丢进去,然后再到Unity 里面建立一个工程,把客户端代码挂到相机上,运行服务端,再运行客户端。 高手勿喷!~!

完全源码已经奉上,大家开始研究吧!! 嘎嘎嘎!

 

服务端代码:Program.cs

  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Text;
  5. using System.Net.Sockets;
  6. namespace SoketDemo
  7. {
  8. class Program
  9. {
  10. // 设置连接端口
  11. const int portNo = 500;
  12. static void Main(string[] args)
  13. {
  14. // 初始化服务器IP
  15. System.Net.IPAddress localAdd = System.Net.IPAddress.Parse("127.0.0.1");
  16. // 创建TCP侦听器
  17. TcpListener listener = new TcpListener(localAdd, portNo);
  18. listener.Start();
  19. // 显示服务器启动信息
  20. Console.WriteLine("Server is starting...n");
  21. // 循环接受客户端的连接请求
  22. while (true)
  23. {
  24. ChatClient user = new ChatClient(listener.AcceptTcpClient());
  25. // 显示连接客户端的IP与端口
  26. Console.WriteLine(user._clientIP + " is joined...n");
  27. }
  28. }
  29. }
  30. }

服务端代码:ChatClient.cs

  1. using System;
  2. using System.Collections.Generic;

  41. return;
  42. }
  43. else
  44. {
  45. string messageReceived = System.Text.Encoding.ASCII.GetString(data, 0, bytesRead);
  46. if (ReceiveNick)
