C#tcp套接字服务器客户端连接

Question

真的需要你帮忙。

我的项目是通过电缆连接两台PC机，并使用tcp套接字将客户端文本框形式的字符串发送到服务器。问题是ATI只能发送一个字符串，然后连接就会关闭。

       String str = textBox2.Text;
       Stream stm = tcpclnt.GetStream();

        ASCIIEncoding asen = new ASCIIEncoding();
    byte[] ba = asen.GetBytes(str);
 textBox1.Text="Sending...";

 stm.Write(ba,0,ba.Length);

  byte[] bb = new byte[100];
  int k = stm.Read(bb,0,100);

 for (int i = 0;i < k; i++)
 {
  Console.Write(Convert.ToChar(bb[i]));
  }


    tcpclnt.Close();

 //////////////

   int k = 0;
   byte[] b = new byte[100];
   for (; ; )
   {
       for (int i = 0; i < 100000; i++)
       { }
           k = s.Receive(b);
       MessageBox.Show(k + "");
       textBox1.Text = "Recieved...";

       for (int i = 0; i < k; i++)
       {
           textBox2.Text = textBox2.Text + Convert.ToChar(b[i]);
       }
       MessageBox.Show(k + "");
       ASCIIEncoding asen = new ASCIIEncoding();
       s.Send(asen.GetBytes("Automatic message:" + "String received by server!"));
       textBox1.Text = "\n Automatic message sent!";


       MessageBox.Show(k + "");
     s.Close();
       }

注意：某个端口上的连接将在表单加载中建立并成功。

首先，将close移出For循环

   int k = 0;
   byte[] b = new byte[100];
   for (; ; )
   {
       for (int i = 0; i < 100000; i++)
       { }
       k = s.Receive(b);
       MessageBox.Show(k + "");
       textBox1.Text = "Recieved...";

       for (int i = 0; i < k; i++)
       {
           textBox2.Text = textBox2.Text + Convert.ToChar(b[i]);
       }
       MessageBox.Show(k + "");
       ASCIIEncoding asen = new ASCIIEncoding();
       s.Send(asen.GetBytes("Automatic message:" + "String received by server!"));
       textBox1.Text = "\n Automatic message sent!";


       MessageBox.Show(k + "");
     }
     s.Close();
