Question

I have lets say two processes: notepad and taskmgr open. I want to kill those two or few more processes how can i do this?
So far i came up with this by googling around:

Process.GetProcesses().Where(p => p.ProcessName == "notepad,taskmgr").ToList().ForEach(y => y.Kill());

not sure how to differentiate between two processes above?

That linq query looks to be only finding a process when its name is “notepad,taskmgr”. To get both, use a query like this:

Process.GetProcesses().Where(p => p.ProcessName == "notepad" || p.ProcessName == "taskmgr").ToList().ForEach(y => y.Kill());

If you’re going to be adding more processes, you might want to do something like this:

var processNamesToKill = new List<string> { "notepad", "taskmgr", "someotherprocess" };
Process.GetProcesses().Where(p => processNamesToKill.Contains(p.ProcessName)).ToList().ForEach(y => y.Kill());

You can then add other processes to that list. As for figuring out what ones you’ve found, in your ForEach, you can access the name by y.ProcessName and use it in a conditional, where needed.

Edit: add .exe to those process names if needed.
