将命令读入命令行C＃

Question

Essentially what I want to do is be able to take a string

byte[] RecPacket = new byte[1000];

//Read a command from the client.

Receiver.Read(RecPacket, 0, RecPacket.Length);

//Flush the receiver

Receiver.Flush();

//Convert the packet into a readable string

string Command = Encoding.ASCII.GetString(RecPacket);

and have the application put it into the command line itself without the user doing it. As far as the research I've done I cannot find a way to directly do that. I found a roundabout way in which you do this

switch (Command)
{
case "SHUTDOWN":

string shutdown = Command;

//Shuts it down

System.Diagnostics.Process SD = new System.Diagnostics.Process();

SD.StartInfo.FileName = "shutdown -s";

SD.Start();

break;

}

but that doesn't seem to work and it also doesn't allow you to do any command available in the windows command line. My goal is to remotely access the command line and be able to send any command to it. Can someone help me out with this?

Answer 1

You can start a cmd application using Process class, and redirect the input to Process.StandardInput so you will be able to execute commands in the console:

ProcessStartInfo info = new ProcessStartInfo("cmd.exe");
info.UseShellExecute = false;
info.RedirectStandardInput = true;

var process = Process.Start(info);

And use it in this way:

string command = "shutdown -s";
process.StandardInput.WriteLine(command);
