如何将VB结构的对象传递给VC ++ DLL结构？

Question

------------------------------------ VB Code --------- ---------------------------

Public Class Form1

    Public Structure Test_Structure
        Dim xyz As Integer
        Dim abc As System.String
    End Structure 

    Dim OBJ_Structure As New Test_Structure
    Dim OBJ_Dll As New Test_Dll

    Public Sub Temp()
        OBJ_Dll.Dll_Function(OBJ_Structure) 
    End Sub
End Class

-------------------------------- VC ++代码------------- -----------------------

Public ref Class Dll
{
    public ref struct Temp
    {
        int xyz;
        System::String^ abc;
    };

    int Dll_Function(Temp^ obj_Temp);
};

如上所示，我想将VB Structure（非托管）的对象传递给VC ++ Structure（托管）。但是我得到了类型转换的错误。应该解决这个问题。
