Using C++ code in a C# project.

I have a curve fitting algorithm in templated C++ and I want to use it in my C# project.

I need to figure out what I need to do to use this code without translating it into C#.

I'm told I could make a component out of it, but I don't know how.
I was told something about 'unsafe' code... don't know how...
Help?

Create a DLL project in C++ that contains your method(s).

Use DLLImport to call your methods from your C# code.

Example here:

Ok thats a good starting point.
I need to pass an array of floats to the dll and I'm really not sure what C# is passing and what C++ is receiving...

If the algorithm really complicated? If not, why not just re-write it in C#?
