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

Verifying the Status of a Windows Service from a C# Application

In a C# application running on Windows XP Embedded, you may encounter the need to determine whether a specific Windows Service is currently active. This is particularly useful when your application relies on communication with a watchdog implemented as a Windows Service. To achieve this, consider the following techniques:

Using the System.ServiceProcess Namespace:

Include the System.ServiceProcess namespace in your application and utilize the ServiceController class to interact with Windows services.

using System.ServiceProcess;

ServiceController sc = new ServiceController(serviceName);

Checking the Service Status:

Obtain the current status of the service using the Status property of the ServiceController. The possible values include:

• Running
• Stopped
• Paused
• StopPending
• StartPending
• StatusChanging

switch (sc.Status)
{
    case ServiceControllerStatus.Running:
        // Service is running
        break;
    // Handle other status values here...
}

Refreshing the Status:

To obtain the latest status of the service, call the Refresh() method on the ServiceController before checking the Status property.

Note: The WaitforStatus() method in the ServiceController class allows you to wait for a specific status within a specified timeout period. This technique may be beneficial in certain scenarios.
