Use dll from C# class in Groovy Script

[GeorgeM]

Hello there.

I am trying to call a function from a dll generated from a C# class.

I use the following script:

import com.sun.jna.Native
import com.sun.jna.Library

interface Hello extends Library {
String GregFunc()
}

def nativeLibraryC = Native.loadLibrary('TestSas', Hello.class)

def methods = nativeLibraryC.getClass().getDeclaredMethods()

for (method:methods) log.info(method);

def lala = nativeLibraryC.GregFunc()

log.info(lala)

GregFunc() normaly should just return a string.

The problem is that even though library is loaded i get an error message that GregFunc() cannot be found.

Can anyone help?

@GeorgeM This sounds like a very interesting problem. Would you be able to provide a sample DLL that I could poke at this with? Otherwise I can try to find one that might be similar to use.

Hi @groovyguy .

Thanks for your interest.

I am sharing my dll.

It is pretty simple, i created a class project, there a class "TestClass" in namespace TestSas.

This TestClass has a function "TestFunc" that returns a string message.

The names are a little different from the ones at the script.

I bulti the project, took the dll and placed it in system32 folder but script cannot execute the function.

I dont know if my way is correct, please let me know if you have any feedback!

Thanks again.
