Executing Command line .exe with parameters in C#

Wait for the process to end (let it do its work):

ProcessStartInfo procStartInfo = new ProcessStartInfo("cmd", "/c " + command);

procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
procStartInfo.CreateNoWindow = true;

// wrap IDisposable into using (in order to release hProcess) 
using(Process process = new Process()) {
  process.StartInfo = procStartInfo;
  process.Start();

  // Add this: wait until process does its work
  process.WaitForExit();

  // and only then read the result
  string result = process.StandardOutput.ReadToEnd();
  Console.WriteLine(result);
}
