How to send Args[] or Messages to Rhino when the process is opening

Hello everyone ,here is my question,How to send Args[] or Messages to Rhino when the process is opening.
i want to drive Rhino to read script file using other application.
for example ,i wrote a simple code ,like this

System.Diagnostics.Process.Start(@“C:\Program Files\Rhinoceros 5 (64-bit)\System\Rhino.exe”,"-LoadScript");

But the message “***-LoadScript***” doesnt work …is there something wrong ?

Does this help?

Yes,that is what i need!
Thank u very much!!
