if you want to use your c language function try to make a dll for this, and use dll with com components in your .net application. — AsifQadri

You either have to build the C file into it's own DLL and then use P/Invoke in your C# code to call them or...

You could also try to port the C code to C# which would give you a completely managed codebase.

I would recommend the second option.

@Alexander - If the C code-base is small, then I would agree. However, I've seen some pretty monolithic C files that would be difficult to port to C#.
