How to start, stop and verify if a service exists in C#

Here’s how you can start, stop, and verify the existence of a service using C#
To check if a service exists on the system, you can use the ServiceController.GetServices()
method and check if your service name is in the list.
public bool ServiceExists(string serviceName) { return ServiceController.GetServices().Any(serviceController => serviceController.ServiceName.Equals(serviceName)); }
It can be easily used as
string serviceName = "YourServiceName"; if (ServiceExists(serviceName)) { Console.WriteLine("Service exists."); } else { Console.WriteLine("Service does not exist."); }
To start a service, use the ServiceController.Start()
method
public void StartService(string serviceName) { using (ServiceController serviceController = new ServiceController(serviceName)) {// Check the service if the current status is stopped.
if (serviceController.Status != ServiceControllerStatus.Running) {// Start the service, and wait until its status is "Running".
serviceController.Start(); serviceController.WaitForStatus(ServiceControllerStatus.Running, TimeSpan.FromSeconds(10)); Console.WriteLine("Service started successfully."); } else { Console.WriteLine("Service is already running."); } } }
To stop a service, use the ServiceController.Stop()
method
public void StopService(string serviceName) { using (ServiceController serviceController = new ServiceController(serviceName)) { // Check the service if the current status is running. if (serviceController.Status != ServiceControllerStatus.Stopped) { // Stop the service, and wait until its status is "Stopped". serviceController.Stop(); serviceController.WaitForStatus(ServiceControllerStatus.Stopped, TimeSpan.FromSeconds(10)); Console.WriteLine("Service stopped successfully."); } else { Console.WriteLine("Service is already stopped."); } } }
You can adjust the TimeSpan
parameter in WaitForStatus
to suit your application's requirements for waiting until the service reaches the desired state.
To verify if a service is active (running), you can use the ServiceController
class in C#.
public static bool IsServiceRunning(string serviceName) { using(ServiceController serviceController = new ServiceController(serviceName)) { return serviceController.Status == ServiceControllerStatus.Running; } }
You need to check the Status
property of the ServiceController
object. If the Status
is ServiceControllerStatus.Running
, it means the service is currently active.
To reboot a service you can modify your code as shown below.
public void RebootService(string serviceName) { if (ServiceExists(serviceName)) { if (serviceIsRunning(serviceName)) { StopService(serviceName); } else { StartService(serviceName); } } else { Console.WriteLine("The service {0} doesn't exists", serviceName); } }
