GJM: Unity3D基于Socket通讯例子 [转载]

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;
3. using System.Linq;
4. using System.Text;
5. using System.Collections;
6. using System.Net.Sockets;

18. {
19. this._client = client;
20. this._clientIP = client.Client.RemoteEndPoint.ToString();
21. // 把当前客户端实例添加到客户列表当中
22. ALLClients.Add(this._clientIP, this);
23. data = new byte[this._client.ReceiveBufferSize];
24. // 从服务端获取消息
25. client.GetStream().BeginRead(data, 0, System.Convert.ToInt32(this._client.ReceiveBufferSize), ReceiveMessage, null);
26. }
27. // 从客戶端获取消息
28. public void ReceiveMessage(IAsyncResult ar)
29. {
30. int bytesRead;
31. try
32. {
33. lock (this._client.GetStream())
34. {
35. bytesRead = this._client.GetStream().EndRead(ar);
36. }
37. if (bytesRead < 1)
38. {
39. ALLClients.Remove(this._clientIP);
40. Broadcast(this._clientNick + " has left the chat");
41. return;
42. }
43. else
44. {
45. string messageReceived = System.Text.Encoding.ASCII.GetString(data, 0, bytesRead);
46. if (ReceiveNick)
47. {
48. this._clientNick = messageReceived;
49. Broadcast(this._clientNick + " has joined the chat.");
50. //this.sendMessage("hello");
51. ReceiveNick = false;
52. }
53. else
54. {
55. Broadcast(this._clientNick + ">" + messageReceived);
56. }
57. }
58. lock (this._client.GetStream())
59. {
60. this._client.GetStream().BeginRead(data, 0, System.Convert.ToInt32(this._client.ReceiveBufferSize), ReceiveMessage, null);
61. }
62. }
63. catch (Exception ex)
64. {
65. ALLClients.Remove(this._clientIP);
66. Broadcast(this._clientNick + " has left the chat.");
67. }
68. }
69. // 向客戶端发送消息
70. public void sendMessage(string message)
71. {
72. try
73. {
74. System.Net.Sockets.NetworkStream ns;
75. lock (this._client.GetStream())
76. {
77. ns = this._client.GetStream();
78. }
79. // 对信息进行编码
80. byte[] bytesToSend = System.Text.Encoding.ASCII.GetBytes(message);
81. ns.Write(bytesToSend, 0, bytesToSend.Length);
82. ns.Flush();
83. }
84. catch (Exception ex)
85. {
86. }
87. }
88. // 向客户端广播消息
89. public void Broadcast(string message)
90. {
91. Console.WriteLine(message);
92. foreach (DictionaryEntry c in ALLClients)
93. {
94. ((ChatClient)(c.Value)).sendMessage(message + Environment.NewLine);
95. }
96. }
97. }
