Is there any way to call an exe as a process inside onstart of a windows service in C#

protected override void OnStart(string[] args)
{
  startTheProcess();
}

protected override void OnStop()
{
  stopTheProcess();
}  

public void startTheProcess()
{
 string path = "testExePath.exe";
 ProcessStartInfo startInfo = new ProcessStartInfo();
 startInfo.CreateNoWindow = false;
 startInfo.UseShellExecute = false;
 startInfo.FileName = path;
       try
        {
          using (Process exeProcess = Process.Start(startInfo))
          {
            exeProcess.WaitForExit();
          }
         }
       catch
        {
         // Log error.
        }
 }

 public void stopTheProcess()
 {
  foreach (var node in Process.GetProcessesByName("Dentrix.WebConnector.Api"))
  {
    node.Kill();
   }

}
