No, it's not.

However, you can use this simple code:

ServiceController sc = new ServiceController("FirebirdGuardianDefaultInstance"); // or "FirebirdServerDefaultInstance" if you are not using Guardian

  
Console.WriteLine("Stopping service...");
sc.Stop();
   
while (sc.Status != ServiceControllerStatus.Stopped)
 Thread.Sleep(100);
   
Console.WriteLine("Service stopped.");

Console.WriteLine("Starting service...");
sc.Start();
   
while (sc.Status != ServiceControllerStatus.Running)
 Thread.Sleep(100);
   
Console.WriteLine("Service started.");

You need to reference System.ServiceProcess.dll and add these usings:

using System.ServiceProcess;
using System.Threading;
