Here is the awesome VB.Net code to check whether the windows service is running or not by passing the service name:

Instructions:

• Open a New Console application
• Add a new bas module called modMain
• Set a reference to System.ServiceProcess (Go to Project > Add Reference and select System.ServiceProcess under .Net tab and click OK.)
• Copy the following code to modMain bas module

Module modMain
  Sub Main()
    If IsServiceRunning("Print Spooler") Then
      Console.WriteLine("Print Spooler Service Running in this machine." & vbCrLf)
    Else
      Console.WriteLine("Print Spooler Service not running in this machine; or the service doesn't exists.\n" & vbCrLf)
    End If
    Console.WriteLine("Hit Enter to exit.")
    Console.Read()
  End Sub
  Function IsServiceRunning(ByVal sServiceName As String) As Boolean
    Try
      Dim myServiceController As ServiceProcess.ServiceController
      myServiceController = New ServiceProcess.ServiceController(sServiceName)
      Return myServiceController.Status = ServiceProcess.ServiceControllerStatus.Running
    Catch ex As Exception
      Console.WriteLine(ex.ToString)
      Return False
    End Try
  End Function
End Module
