在c＃中使用socket获取数据的正确方法是什么 [英] what is the right way to get the data using socket in c#

问题描述

这是Sever Code，我从客户端接收数据但每次在数据前都有一个特殊符号。



例如：

如果客户端发送1然后

在服务器中我将得到外出：@ 1任何符号

像这样得到特殊符号和值。

This is the Sever Code, am receiving the data from the client but every time am getting one special symbol before the data.

For Example :
If client sends 1 then
In The Server i will get outout: @1 any symbols
like this am getting special symbols and values.

try {
    int Port = 8088;
    TcpListener server = new TcpListener(IPAddress.Any, Port);
    server.Start()
    byte[] bytes = new byte[1024];
    string data;
    while (true)
      {
        Console.Write("Waiting for Client connection... ");
        TcpClient client = server.AcceptTcpClient();
        Console.WriteLine("\nClient Connected....!");
        NetworkStream stream = client.GetStream();
        int i;
        i = stream.Read(bytes, 0, bytes.Length);
        while (i != 0)
           {
              i = stream.Read(bytes, 0, bytes.Length);
              data = System.Text.Encoding.ASCII.GetString(bytes, 0,i);
              Console.WriteLine(string.Format("Received:{0}",data));
             }
       client.Close();
     }
 }
catch (SocketException e)
 {
    Console.WriteLine("SocketException: {0}", e);
 }

推荐答案

您不能直接应用AcceptTcpClient，就好像它返回客户端实例一样。它也是完全无用的，因为你只能从也作为服务器运行的软件连接。



这里有几个关于codeproject的例子，你可以查看：

更高级：

祝你好运！

You can't directly apply AcceptTcpClient as if it returns a client instance. It would also be complete useless because you could only connect from the software that also runs as a server.

There are several examples here on codeproject you can check out:
A TCP/IP Server written in C#[^]

More advanced:

Good luck!

int Port = 8088;
 TcpListener server = new TcpListener(IPAddress.Any, Port);
 server.Start(); 
 byte[] bytes = new byte[1024];
 string data;
 Console.Write("Waiting for Client connection ");
  TcpClient client = server.AcceptTcpClient();
  Console.WriteLine("\n Client Connected");
   NetworkStream stream = client.GetStream();
   int i;
i = stream.Read(bytes, 0, bytes.Length);
data = Encoding.UTF8.GetString(bytes, 0, i);
 data=data.Substring(2, data.Length-2);
 Console.WriteLine(string.Format("Data Received :{0}", data));
  client.Close()
