unity中建立 Socket 简单通信

本人是新手，但是找了很久都找不到类似的通讯源码，后来终于在一个网站上看到有关于Socket的通讯事例，所以就抄过来希望能够帮助更多像我一样的初学者！嘻嘻

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
