Is it possible to infer that a ParameterInfo object refers to a function pointer containing managed parameter types?

Question

I'm using reflection to examine the following method declaration and am wondering if it is possible to determine that the method's sole parameter is a function pointer.

public ref class T
{
public:
    void foo(Int32 (*)(String^, array<TimeSpan>^)) { }
};

When inspecting the ParameterInfo object for foo's parameter, it shows that the parameter's type is IntPtr; this makes sense since a function pointer is not a native CLR type.

Since the function pointer contains only managed parameter types, I was hoping to get some extra context in the ParameterInfo. I don't see any properties or attributes in ParameterInfo and Type that may help me distinguish this IntPtr instance as a function pointer -- are there any?

After some thought, I'm very sure this is not possible. Since the function argument to foo is a native pointer, the managed reflection system can't see beyond that layer and will always present the argument as IntPtr.
