Run a command line from a running application through c#

Question

I've searched around and didn't find anything useful! :(

What i want is to have my C# app doing a command to a running process. This running process is a console application and i just need to enter the command "restart".. my try was:

Process[] processes = Process.GetProcessesByName("OpenSim.32BitLaunch"); foreach (Process p in processes) { p.StandardInput.WriteLine("restart"); }

Just because you're looping through processes, that doesn't mean any statements inside the loop are doing anything to the processes. Console.WriteLine writes text to standard output, and has nothing to do with p. — Phil

You should write to p.StandardInput.

Instead of

Console.WriteLine("restart");

Use

p.StandardInput.WriteLine("restart");

Thanks by your help guys :) I've managed to solve using SetForegroundWindow and SendKeys. It was something just like this (remember to import the respective dll's first):

System.Diagnostics.Process process = Process.GetProcessesByName("OpenSim.32BitLaunch")[0]; Process[] processes = Process.GetProcessesByName("OpenSim.32BitLaunch"); foreach (Process p in processes) { SetForegroundWindow(p.MainWindowHandle); Thread.Sleep(1000); SendKeys.SendWait("quit"); Thread.Sleep(1000); SendKeys.SendWait("{ENTER}"); }
