Question

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

Answer 1

An example using by ServiceController Class

private void RestartWindowsService(string serviceName)
{
    ServiceController serviceController = new ServiceController(serviceName);
    try
    {
        if ((serviceController.Status.Equals(ServiceControllerStatus.Running)) || (serviceController.Status.Equals(ServiceControllerStatus.StartPending)))
        {
            serviceController.Stop();
        }
        serviceController.WaitForStatus(ServiceControllerStatus.Stopped);
        serviceController.Start();
        serviceController.WaitForStatus(ServiceControllerStatus.Running);
    }
    catch
    {
        ShowMsg(AppTexts.Information, AppTexts.SystematicError, MessageBox.Icon.WARNING);
    }
}

Answer 2

You can set a service to restart after failure. So a restart can be forced by throwing an exception.

Use recovery tab on service properties.

Be sure to use reset fail count property to prevent service stopping altogether.

Answer 3

Call Environment.Exit with an error code greater than 0, which seems appropriate, then on install we configure the service to restart on error.

Environment.Exit(1);

I have done same thing in my Service. It is working fine.

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.
