How can I restart a windows service programatically in .NET

Question

How can I restart a windows serice programatically in .NET? Also, I need to do an operation when the service restart is completed.

Answer 1

Take a look at the ServiceController class.

To perform the operation that needs to be done when the service is restarted, I guess you should do that in the Service yourself (if it is your own service). If you do not have access to the source of the service, then perhaps you can use the WaitForStatus method of the ServiceController.

Answer 2

This article uses the ServiceController class to write methods for Starting, Stopping, and Restarting Windows services; it might be worth taking a look at.

Snippet from the article (the "Restart Service" method):

public static void RestartService(string serviceName, int timeoutMilliseconds)
{
  ServiceController service = new ServiceController(serviceName);
  try
  {
    int millisec1 = Environment.TickCount;
    TimeSpan timeout = TimeSpan.FromMilliseconds(timeoutMilliseconds);

    service.Stop();
    service.WaitForStatus(ServiceControllerStatus.Stopped, timeout);

    // count the rest of the timeout
    int millisec2 = Environment.TickCount;
    timeout = TimeSpan.FromMilliseconds(timeoutMilliseconds - (millisec2-millisec1));

    service.Start();
    service.WaitForStatus(ServiceControllerStatus.Running, timeout);
  }
  catch
  {
    // ...
  }
}

See this article.

Here is a snippet from the article.

//[QUICK CODE] FOR THE IMPATIENT
using System;
using System.Collections.Generic;
using System.Text;
// ADD "using System.ServiceProcess;" after you add the 
// Reference to the System.ServiceProcess in the solution Explorer
using System.ServiceProcess;
namespace Using_ServiceController{
    class Program{
        static void Main(string[] args){
            ServiceController myService = new ServiceController();
            myService.ServiceName = "ImapiService";
            string svcStatus = myService.Status.ToString();
                if (svcStatus == "Running"){
                    myService.Stop();
                }else if(svcStatus == "Stopped"){
                    myService.Start();
                }else{
                    myService.Stop();
                }
        }
    }
}

Answer 4

How about

   var theController = new System.ServiceProcess.ServiceController("IISAdmin");

   theController.Stop();
   theController.Start();

Don't forget to add the System.ServiceProcess.dll to your project for this to work.

Answer 5

You could also call the net command to do this. Example:

System.Diagnostics.Process.Start("net", "stop IISAdmin");
System.Diagnostics.Process.Start("net", "start IISAdmin");
