What is the correct way to restart IIS Server from c# code?

Question

I have console application running from Admin user. I want to restart IIS server using C#. I made this:

        public static void Stop()
        {
            string serviceName = "W3SVC";
            var service = GetService(serviceName);

            if (service == null) return;

            ServiceController sc = new ServiceController(service.ServiceName);

            sc.Stop();
        }

        public static void Start()
        {
            string serviceName = "W3SVC";
            var service = GetService(serviceName);

            if (service == null) return;

            ServiceController sc = new ServiceController(service.ServiceName);

            sc.Start();
        }

        {
            return ServiceController.GetServices()
                .Where(x => x.ServiceName == name).FirstOrDefault();
        }

The problem that when i stop server, sometimes i get this "visual studio just in time debugger error an unhandled exception", even if my visual studio is not open. I deleted this option from visual studio. But it made me think - am i doing restart right way?

Why starting and stoping my way takes like 5-6 seconds, while if i restart server from iis manager, it restarts for 1 sec.

So what is the correct way to restart server from c# code?

Try to use this code to restart IIS.

using System.ServiceProcess;

using (ServiceController controller = new ServiceController())
{
   controller.MachineName = “My local or remote computer name”;
   controller.ServiceName = “IIS Service Name”; // i.e “w3svc”

   if (controller.Status != ServiceControllerStatus.Running)
   {
      // Start the service
      controller.Start();

       Log.Debug(“IIS has been started successfully, now checking again for 
       webservice availability”);

   }
   else
   {
      // Stop the service
      controller.Stop();

      // Start the service
      controller.Start();

        Log.Debug(“IIS has been restarted successfully”);

    }

  }
