Web客户端

添加命名空间:
using System.Net;
using System.Net.Sockets;
using System.Text;

连接代码:
private void socketButton_Click(object sender, System.EventArgs e)
  {//连接服务器程式
   try
   {
    //开始连接
    TcpClient client=new TcpClient("192.168.0.100",81);
    NetworkStream ns=client.GetStream();
    byte[] byteTime=Encoding.BigEndianUnicode.GetBytes("客户端数据提交\n");
    ns.Write(byteTime,0,byteTime.Length);
    //返回客户端信息
    byte[] clientIp=Encoding.BigEndianUnicode.GetBytes("客户端IP地址:"+Request.UserHostAddress+"\n");
    ns.Write(clientIp,0,clientIp.Length);
    byte[] bytes=new byte[1024];
    int bytesRead=ns.Read(bytes,0,bytes.Length);
    showLabel.Text="服务器返回信息"+Encoding.ASCII.GetString(bytes,0,bytesRead);
    client.Close();
   }
   catch(Exception ex)
   {
    showLabel.Text="抛出异常"+ex.ToString();
   }
   finally{}
  }
