I have a CLI/C++ interface that I want to examine via .NET Reflection. Here's the function signature in the source code:

class ClassA;
template<typename _Type> class ClassTempA;
public interface class Test : BaseFunc {
public:
    ClassTempA<int>& SomeFunc2(ClassA inst) = 0;

Here's what the function looks like when examined in .NET Reflector:

unsafe ClassTempA<int>* modopt(IsImplicitlyDereferenced) SomeFunc2(ClassA inst);

Is there a way to get at the modopt attributes via .NET reflection, or do I have to use the Metadata Unmanaged API?

You can get the modopt and modreq info from System.Reflection by calling ParameterInfo::GetOptionalCustomModifiers() and ParameterInfo::GetRequiredCustomModifiers(), respectively. To illustrate with your types, see the following.

class ClassA;
template<typename _Type> class ClassTempA;
public interface class Test : BaseFunc {
public:
    ClassTempA<int>& SomeFunc2(ClassA inst) = 0;
array<Type^>^ GetModifiers()
    MethodInfo^ SomeFunc2 = Test::typeid->GetMethod("SomeFunc2");
    return method->ReturnParameter->GetOptionalCustomModifiers();
