How execute Command Prompt(Ms-DOS) commands through C#

DarkSorrow38

I am trying to execute Command Prompt(Ms-DOS) commands through C# like shutdown -s -t 0(and several other commands) by creating an object of System.Diagnostic.Process class. When the Start method is executed a new Command Prompt window opens but the command does not execute.

// code procedure
public static void ExecuteCommand()
{
Process p = new Process("cmd.exe", "shutdown -s -t 0");
p.CreateNoWindow = true;
p.UseShellExecute = false;
p.Start();
}

I have imported the System.Diagnostic namespace. Banking establishments are more dangerous than standing armies.

Why do you need to put the program as a parameter? CMD doesn't accept parameters like that. Just replace the line which creates your Process instantiation with

Process p = new Process("shutdown -s -t 0");

That will run the actual program, not just open a command prompt.

Computafreak, The statement you gave gives a file not found exception.

C:\>cmd /?
Starts a new instance of the Windows XP command interpreter

/C Carries out the command specified by string and then terminates

I think you need the /C parameter.

That's odd. Try just invoking Process.Start(...) instead of manually instantiating the Process class.

Hi, Process.Start("shutdown", "-s -t 0"); is all you need assuming you have sufficient rights. shutdown.exe is one of the Windows utilities, no cmd.exe required here. [ADDED] And with an amended 4-line approach like yours, the DOS window flashing can be avoided. [/ADDED] :)
