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

Verifying Windows Service Status in C#

In a C# application, you may need to check if a particular Windows service is running, especially if it plays a crucial role in your application's functionality. Here's how you can accomplish this:

Using System.ServiceProcess

To work with Windows services, you can utilize the System.ServiceProcess namespace. Add it to your project references under the .NET tab.

using System.ServiceProcess;

ServiceController: A Bridge to Service Status

The ServiceController class serves as a bridge between your code and the Windows service. To create an instance, pass the name of the service you're interested in.

ServiceController sc = new ServiceController(SERVICENAME);

Determining Service Status

The Status property of the ServiceController object provides the current state of the service. You can use a switch statement to handle different statuses:

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";
}

Tips:

• Use sc.Refresh() to retrieve the latest status before every check.
• The sc.WaitforStatus() method can wait for a specific status to occur within a timeout period.
• Refer to the Microsoft documentation for more information on ServiceController: https://docs.microsoft.com/en-us/dotnet/api/system.serviceprocess.servicecontroller?view=netframework-4.8
