QUESTION
I am currently developing a program that uses the Ghost Script DLL, by importing it as so:

When you start your application in the folder which contains the Ghostscript DLL, then the Windows API call DllImport looks in the current working directory and finds the Ghostscript DLL, so it loads it.
When you start in a directory which does not contain the Ghostscript DLL, then DllImport looks in the Current Working Directory, and does not find the DLL. It then searches the search path, which presumably does not find a Ghostscript DLL, so you get an error.
You either need to be sure the current working directory has a copy of the Ghostscritp DLL, or the DLL is on the search path, or you need to supply a fully qualified path to the Ghostscript DLL in the first argument to DllImport.
In case you are considering distributing this application, please read the AGPL license to ensure that you comply with the terms for using Ghostscript.
