I want to use a function from nvapi in C# "NvAPI_DRS_EnumProfiles". I have to call QueryInterface(id) with the id of the function. Everything is working fine and i found the ids for the other functions i need on the web, but i can't find the id of this single function, and i don't know how to get it. I tried so many things and even a c-program which print me the memory-address didn't work.

My code looks something like this: http://www.drivenbynostalgia.com/files/SOP.cs

Thank you for your help :)

c# dll memory-address queryinterface nvapi
