C# wrapper, C++ struct containing CList

[DHarman]

I have a C++ DLL using MFC and I need to wrap all the exported functions so they can be used by a C# .NET front end. For functions taking CStrings, ints, etc this isn't a problem. However, I have some functions which take a struct as a parameter. The problem is, the struct contains a CList of another struct...for example:

struct SOne
{
  CString str1;
  long l1;
  CString s2;
  int i1;
};

struct STwo
{
  CList <struct SOne,struct SOne&> myList;
  CString str1;
  int i2;
};

//The exported function looks like this (export syntax left out for simplicity)
long DoSomthing(struct STwo* me);

So how do I marshal the data for STwo within my wrapper so that DoSomething can be called from a C# front end?

Sorry if I'm using incorrect terminology. I'm a C++ programmer just now venturing into C# so all the C# syntax is new to me.

Thanks in advance for your help.
