C#创建TCP/IP服务端和客户端，含测试demo及源码

小灰灰 2022-05-20 06:19 38阅读 0赞

网上的TCP/IP创建服务端和客户端的方法鱼龙混杂，自己把在使用项目中的TCP服务端和客户端的代码抽了出来，做了demo，以供大家使用参考。

为了方便调用，我把一些基础方法都整合封装到了Reader.dll中，直接调用方法即可，非常方便(伸手党直接下源码运行即可)

源码下载地址：[https://download.csdn.net/download/horseroll/10444188][https_download.csdn.net_download_horseroll_10444188]

源码中包含dll文件，直接下载源码即可

源码程序运行使用方法：先打开服务端，再打开客户端，然后即可互相发送信息

效果图：

### 1.客户端编写 ###

客户端连接方法使用readerCamera.ConnectServer方法，监听事件为ReceiveDataCamera，发送信息为readerCamera.ServerSendMessage方法

1.  public partial class Client : Form
2.  \{
3.  private Reader.ReaderMethod readerCamera; *//摄像头采集类*
4.  public Client()
5.  \{
6.  InitializeComponent();
7.  *//初始化访问实例*
8.  readerCamera = new Reader.ReaderMethod();
9.  *//回调函数*
10. readerCamera.ReceiveCallback = ReceiveDataCamera;
11. \}
12. 
13. private void btnopenclient\_Click(object sender, EventArgs e)
14. \{
15. string strLog = string.Empty;
16. string strException = string.Empty;
17. IPAddress ipAddress = IPAddress.Parse( "127.0.0.1"); *//监听的ip地址*
18. int nPort = 55; *//监听的端口号*
19. int nRet = readerCamera.ConnectServer(ipAddress, nPort, out strException);
20. if (nRet != 0) *//如果连接摄像头失败*
21. \{
22. strLog = "连接摄像头失败，请确认是否已打开服务端，失败原因： " \+ strException;
23. \}
24. else
25. \{
26. strLog = "成功连接摄像头"\+ipAddress+ ":"\+nPort;
27. \}
28. WriteLog(richTextBox1, strLog);
29. \}
30. */// <summary>*
31. */// 客户端接收数据*
32. */// </summary>*
33. */// <param name="btAryReceiveData"></param>*
34. private void ReceiveDataCamera(byte\[\] btAryReceiveData)
35. \{
36. string str = System.Text.Encoding.Default.GetString(btAryReceiveData); *//数据接收转string*
37. *//richTextBox1.AppendText("接收到数据:" + str);直接调用该方法会出现跨线程调用问题*
38. WriteLog(richTextBox1, "接收到数据:" \+ str);
39. \}
40. 
41. private void btnclientsend\_Click(object sender, EventArgs e)*//发送数据*
42. \{
43. readerCamera.ServerSendMessage(System.Text.Encoding.Default.GetBytes(tbclient.Text)); *//发送数据*
44. \}
45. \}

### 2.服务端编写 ###

服务端连接方法使用readerCameraOpenServer方法，监听事件为ReceiveDataCamera，发送信息为readerCamera.ServerSendMessage方法

1.  public partial class Server : Form
2.  \{
3.  private Reader.ReaderMethod readerCamera; *//摄像头采集*
4.  public Server()
5.  \{
6.  InitializeComponent();
7.  Client client = new Client();
8.  client.Show();
9.  *//初始化访问读写器实例*
10. readerCamera = new Reader.ReaderMethod();
11. *//回调函数*
12. readerCamera.ReceiveCallback = ReceiveDataCamera;
13. \}
14. private void btnopenserver\_Click(object sender, EventArgs e)
15. \{
16. readerCamera.OpenServer( 55); *//打开服务端，监听端口55*
17. WriteLog(richTextBox1, "打开端口55成功"); *//点击事件中调用该写入方法不会报错*
18. \}
19. */// <summary>*
20. */// 服务器接收数据*
21. */// </summary>*
22. */// <param name="btAryReceiveData"></param>*
23. private void ReceiveDataCamera(byte\[\] btAryReceiveData)
24. \{
25. string str = System.Text.Encoding.Default.GetString(btAryReceiveData); *//数据接收转string*
26. *//richTextBox1.AppendText("接收到数据:" + str);直接调用该方法会出现跨线程调用问题*
27. WriteLog(richTextBox1, "接收到数据:" \+ str);
28. \}
29. */// <summary>*
30. */// 发消息*
31. */// </summary>*
32. */// <param name="sender"></param>*
33. */// <param name="e"></param>*
34. private void btnserversend\_Click(object sender, EventArgs e)
35. \{
36. readerCamera.ServerSendMessage(System.Text.Encoding.Default.GetBytes(tbserver.Text)); *//发送数据*
37. \}
38. \}
