How do I run an external program like Notepad or Calculator via a C# program?

4Welcome to Stack Overflow. I think it's safe to assume that English is your second language. To increase your chances of getting an answer, I would re-write the question title to say "How to open an external program from a C# program?". Also is it a Console App, Winforms, Web(hopefully not)? Provide a little more information, and make sure you check out the Stack Overflow FAQ.Marko– Marko2010-07-04 05:09:10 +00:00Commented Jul 4, 2010 at 5:09

Maybe it'll help you:
using(System.Diagnostics.Process pProcess = new System.Diagnostics.Process())
{
pProcess.StartInfo.FileName = @"C:\Users\Vitor\ConsoleApplication1.exe";
pProcess.StartInfo.Arguments = "olaa"; //argument
pProcess.StartInfo.UseShellExecute = false;
pProcess.StartInfo.RedirectStandardOutput = true;
pProcess.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
pProcess.StartInfo.CreateNoWindow = true; //not diplay a windows
pProcess.Start();
string output = pProcess.StandardOutput.ReadToEnd(); //The output result
pProcess.WaitForExit();
}

For example like this :
// run notepad
System.Diagnostics.Process.Start("notepad.exe");
//run calculator
System.Diagnostics.Process.Start("calc.exe");
