            myService.ServiceName = "ImapiService";
            string svcStatus = myService.Status.ToString();
                if (svcStatus == "Running"){
                    myService.Stop();
                    myService.Refresh();

}
 string svcStatu = myService.Status.ToString();
                if (svcStatu == "Stopped"){
                    myService.Start();
                    myService.Refresh();

What is the error you got?

bora1891 5-Aug-14 7:01am

ServiceController myService = new ServiceController();
myService.ServiceName = "ImapiService";
string svcStatus = myService.Status.ToString();
if (svcStatus == "Running"){
myService.Stop();
myService.Refresh();
myService.Start();
}
if My code change like this the error will be at myService.Start(); and error is:Cannot start service MSSQL$SQLEXPRESS on computer.

but if my code like this
ServiceController myService = new ServiceController();
myService.ServiceName = "ImapiService";
string svcStatus = myService.Status.ToString();
if (svcStatus == "Running"){
myService.Stop();
myService.Refresh();

}
string svcStatu = myService.Status.ToString();
if (svcStatu == "Stopped"){
myService.Start();
myService.Refresh();
}

program will not to step into second if statement.. why?

First of all, why are you calling ToString on ServiceController.Status? Why not use the provided enum? Also, there are more states to a service than "Running" and "Stopped". Instead of using inclusive checks, you should use exclusive checks. For example, instead of "if the service is running, do this" try "if the service is not stopped or stopping, do this".
