Hi I am trying to develop a program to crash a large program that runs a big machine.
I know it sounds bad to crash it but if for some reason the machine gets out of hand we can stop the machine but it doesn't stop the program.The C# writes to a plc so the program runs the machine.Windows 10 isn't an option cuz we all hate it.

What I have tried:

I really don't know where to start. I am new to c# and programming in general.Thanks in advance

Pull the plug.

You can stop the machine but the PLC code keeps running like the machine is running?

From just your description, it sounds like you've got much bigger problems than just shutting down the app. You've got sensor and PLC code problems. It sounds like the PLC has no clue what state the machine is at any point and just keeps running like everything is fine. That's bad.

Upgrade it to Windows 10.

Firstly you need a good understanding of programming in general, how programs are built, how they run, and how they react to external events. Next you need a good understanding of the Operating System that your program will run on, and how you can interact with it and with other running programs. Then you need a programming language that lends itself to this sort of task, C or C++ are likely better choices than C#. Finally you need to understand that if the big program is not running correctly, or the machine is not running correctly, your 'crasher' will most likely not run correctly.

And for the record, if you stop the machine how does this other program keep running?

Works starting with windows XP, not available in win 2000 or lower:

This is the quickest way to do it:

Process.Start("shutdown","/s /t 0");

Otherwise use P/Invoke or WMI like others have said.

Edit: how to avoid creating a window

var psi = new ProcessStartInfo("shutdown","/s /t 0");
psi.CreateNoWindow = true;
psi.UseShellExecute = false;
Process.Start(psi);
