Access C#-dll via Excel VBA?

[TRex01]

Hello,

I have scrawled for hours all over google and other forums but haven't found one explanation or code snippet that would fully work on my Excel 2010/Visual Studio C# 2010 environment:

I just want to provide some methods in a *.dll created by C# and then access these methods via Excel VBA. Can anyone help please with suggestions/short code examples that do work?

Thank you very much in advance for every answer/link/code etc.

Thanks MarvinP for the two links, I knew the first one and checked the second but both unfortunately don't help; is it really that hard?
