Selenium C# Tutorial: Working with Process and Services

Sometimes, we will need to validate a system service/process's state prior and after test execution. This article will provide the basic set of tools to accomplish these tasks.

Note: To use the system services/Process, you first need to add the "System.ServiceProcess" as a reference and the "System. Diagnostics" namespace.

Working with services

public class Program
    {        
        static void Main(string[] args)
        {
            //Define the service that we want to use
            ServiceController SpoolerService = new ServiceController("Spooler");

            //Define a TimeSpan that we will use to validate the service status
            TimeSpan Timer = TimeSpan.FromMilliseconds(30);

            //Start a Service
            SpoolerService.Start();
            SpoolerService.WaitForStatus(ServiceControllerStatus.Running, Timer);

            //Stop a Service
            SpoolerService.Stop();
            SpoolerService.WaitForStatus(ServiceControllerStatus.Stopped, Timer);

            //Getting the service status
            Console.WriteLine(SpoolerService.Status);

            //Getting the service name
            Console.WriteLine(SpoolerService.ServiceName);

            //Getting the service Display Name
            Console.WriteLine(SpoolerService.DisplayName);

            //Name of the host ("." is for the local computer)
            Console.WriteLine(SpoolerService.MachineName);

            //Get all service Dependencies 
            ServiceController[] Dependencis = SpoolerService.DependentServices;
            foreach (var item in Dependencis)
            {
                Console.WriteLine(item.DisplayName);
            }

            //Get the type of service
            Console.WriteLine(SpoolerService.ServiceType);          

	     //How to run a specific program 
            WorkingWithProcess.StartInfo.FileName = "notepad.exe";

	    //Selecting the process by ID
 	    Process Process = Process.GetProcessById(94204);

	   //Kill the process
	   Process.Kill();
        }
    }
