C#实现的Socket服务器端、客户端代码分享
作者:junjie 时间:2021-09-29 00:22:28
服务端:
using System;
using System.Collections.Generic;
using System.Net;
using System.Net.Sockets;
using System.Text;
namespace Server
{
class Program
{
static void Main(string[] args)
{
Socket server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPEndPoint point = new IPEndPoint(IPAddress.Parse("127.0.0.1"),55555);
try
{
server.Bind(point);
server.Listen(10);
//监听本地端口
System.Console.WriteLine("开始监听本地端口:55555");
while (true)
{
Socket sock = server.Accept();
byte[] buffer = new byte[1024 * 1024];
int n = sock.Receive(buffer);
String cmd = Encoding.UTF8.GetString(buffer, 0, n);
String result = execCmd(cmd);
byte[] bytes = Encoding.UTF8.GetBytes(result);
sock.Send(bytes);
}
}
catch (Exception ex)
{
System.Console.WriteLine(ex.Message);
return;
}
}
//重定向输入输出流,并且用cmd执行命令
private static String execCmd(String cmd)
{
System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo = new System.Diagnostics.ProcessStartInfo();
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.Arguments ="/c "+cmd;
//隐藏程序外壳
p.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
//在这里重定向输出即可,因为不是交互式的,如果需要交互式的直接反弹cmd即可
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.UseShellExecute = false;
p.StartInfo.CreateNoWindow = true;
p.Start();
return p.StandardOutput.ReadToEnd();
}
}
}
客户端:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;
using System.Windows.Forms;
/*
* Code By iswin
*/
namespace Client
{
public partial class main : Form
{
public main()
{
InitializeComponent();
this.ip.Text="127.0.0.1";
this.cmd.Text="ipconfig";
this.port.Text = "55555";
}
private void send_Click(object sender, EventArgs e)
{
Socket client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
String remoteip=this.ip.Text;
String command = this.cmd.Text;
IPAddress ip = IPAddress.Parse(remoteip);
IPEndPoint point=new IPEndPoint(ip,int.Parse(port.Text));
try
{
this.recvmsg.Text = "开始连接服务端:" + remoteip + ":" + port.Text + "\n";
client.Connect(point);
this.recvmsg.Text="连接服务端!\n给服务端发送指令:"+command;
byte[] buffer = Encoding.UTF8.GetBytes(command);
//讲输入的指令发送到服务端
client.Send(buffer);
//接受服务端返回的数据
recvmsgs(client);
client.Close();
}
catch (Exception ex)
{
this.recvmsg.Text = ex.Message;
MessageBox.Show(ex.Message);
return;
}
}
//接受服务端发送来的消息
private void recvmsgs(Socket client)
{
try
{
byte[] buffer = new byte[1024 * 1024];
int size = client.Receive(buffer);
String recv = Encoding.UTF8.GetString(buffer, 0, size);
this.recvmsg.Text = "\n" + recv;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
return;
}
}
}
}
