Export generic code (List)to COM [duplicate]

This question already has answers here:

What are alternatives to generic collections for COM Interop? (4 answers)

Closed 6 years ago.

COM doesn't support generics?What would be the best way to replicate this List<T> so that it's COM visible in the tlh file. EDIT:: c#::

[ComVisible(true)]
    [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    [Guid("FA677671-5E26-4307-AD2B-19BF1E7AFF8B")]
    public interface IEvents
    {
        IEvents[] CreateListeners();
    }

in C++ i have,

CComSafeArray<CSharp::IEvents> ppSA;
    pInterface->CreateListeners(ppSA->GetSafeArrayPtr());

My question what i should do in this Create instance function so asto replicate this statement List evt=new List(); in the managed c#?

回答1:

Correct, generic types are not supported:

The COM model does not support the concept of generic types. Consequently, generic types cannot be used directly for COM interop.
