Managed C++/CLI

The compiler complains it won't compile .c files with the /clr syntax.

Anyway, try to simply rename the c files to cpp and compile. You may get some compiler errors, but they should not be hard to fix.

Or put the C files into a native DLL and export the required functions out of it.

Out of curiosity - would it work with a static lib rather than a dll? I am too lazy to try

I'm not a C++ guy by trade, so maybe this is a stupid question, but how do I export the native functions out of it so that my C++/CLI dll can see those functions?

I've got a C++/CLI library I'm using to wrap some native C methods in order to call them easily from another .NET language.

This is probably an easy question, but how can I convert a .NET string (System::String) to a LPCSTR? I'm new the the CLI extensions for C++, and google doesn't give me anything other than the old MSDN article which refers to solutions using the old MC++ syntax.
