ServiceController - Can't stop the service [C#]

Question

I read many posts here with a similar question, but none helped me solve my problem. I want to stop the service with the ServiceController object. But it fails and I get an exception: System.ComponentModel.Win32Exception (0x80004005). I don't understand why.. I run the program with "Run as administrator".

ServiceController ctrl = ServiceController.GetServices().Where(s => s.ServiceName == "service_name").SingleOrDefault();
if (ctrl == null) return;

if (ctrl.Status.Equals(ServiceControllerStatus.Running))
{
   try 
   {
      ctrl.Stop();
   }
   catch(Exception ex)
   {
      Log(ex.ToString(), 3);
   }
}

If I call the net stop command from the code, then everything works. Why?

 Process cmd = new Process();
cmd.StartInfo.FileName = "cmd.exe";
cmd.StartInfo.CreateNoWindow = true;
cmd.StartInfo.RedirectStandardInput = true;
cmd.StartInfo.RedirectStandardOutput = true;
cmd.StartInfo.UseShellExecute = false;
cmd.Start();
cmd.StandardInput.WriteLine("net stop service_name");
cmd.StandardInput.Flush();
cmd.StandardInput.Close();
cmd.WaitForExit();

After our continued chat discussion ServiceController following was discovered :

ServiceController was able to Start the service, but not Stop
From the System Logs it was evident that ServiceController crashes when trying to stop
ServiceControllers Start & Stop works fine with other services such as PrintSpooler
Using CMD or Process.Start we can stop service by sc stop "servicename"
Finally the problem was with the Service itself and the way it was constructed
