How Can I Check the Status of a Windows Service Using C#?

Checking the Status of a Windows Service Using C#

In your application, you need to verify if a specific Windows Service is running. To accomplish this task, follow these steps:

Implementing the Verification Logic

1. Add a reference to the System.ServiceProcess namespace to your project.
2. Create an instance of the ServiceController class, specifying the name of the service you want to check (e.g., ServiceController sc = new ServiceController("ServiceName");).
3. Use the Status property to determine the current state of the service.

Possible Service Statuses

The Status property can return one of the following values:

• ServiceControllerStatus.Running: The service is running.
• ServiceControllerStatus.Stopped: The service is stopped.
• ServiceControllerStatus.Paused: The service is paused.
• ServiceControllerStatus.StopPending: The service is in the process of stopping.
• ServiceControllerStatus.StartPending: The service is in the process of starting.
• ServiceControllerStatus.StatusChanging: The service is changing its status.

Example Code

The following code sample demonstrates how to check the status of a service and return an appropriate response:

using System.ServiceProcess;

ServiceController sc = new ServiceController(SERVICENAME);

switch (sc.Status)
{
    case ServiceControllerStatus.Running:
        return "Running";
    case ServiceControllerStatus.Stopped:
        return "Stopped";
    case ServiceControllerStatus.Paused:
        return "Paused";
    case ServiceControllerStatus.StopPending:
        return "Stopping";
    case ServiceControllerStatus.StartPending:
        return "Starting";
    default:
        return "Status Changing";
}

Additional Notes

• To update the status after making any changes to the service, call the sc.Refresh() method.
• Alternatively, you can use the sc.WaitForStatus method to wait for a specific status or a timeout period.
