Needed to check some servers to make sure a Windows service was available, so wrote this code to keep an eye on them today:
C#
public static bool IsServiceInstalled(string serviceName)
{
// get list of Windows services
ServiceController[] services = ServiceController.GetServices();

// try to find service name
foreach (ServiceController service in services)
{
if (service.ServiceName == serviceName)
return true;
}
return false;
}

public bool IsWindowsWindowsServiceRunning(string windowsServiceName, string windowsServiceHost ) ServiceController sc = new ServiceController(windowsServiceName, windowsServiceHost);

}

return (sc.Status == ServiceControllerStatus.Running);

{
