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");
