How to start the ApacheDS as a windows service in background using batch file or powershell script?

I want to write a batch file or powershell script as a wrapper that can invoke apacheds.bat provided by ApacheDS to create a new ApacheDS instance and register it as a windows service.

Currently I use C# to create powershell process and pass argument: "-c & '$scriptFullName' -Service" to powershell process's CommandLine attribute. ($scriptFullName is the path to my powershell script). So when I want to start the service, the powershell.exe process will start and execute the command from CommandLine attribute.

However, now after running the powershell script, I find no new powershell.exe process with the passed argument in CommandLine attribute is created. The weird thing is that, in OnStart() method in #C code, p.Start() returns true, which means a new process is created. So now I am stuck on this part.

I attached part of the code below (C# code for service process, code for handling install, start, and service options). It would be greatly appreciated if anyone can help!

$adsStartCmd = "C:\apacheds\bin\apacheds.bat"

$serviceName = "eGranaryADS"
$installDir = "C:\apacheds\$serviceName" # Where to install the service files
$scriptCopy = "$installDir\$scriptName"
