visual-c++ - 为什么以下代码不会覆盖 C++ CLI 中的基类属性？

Question

我是一名 C# 程序员，对 C++ 不太了解。 知道为什么我会收到错误吗？

ref class masterWeapon{
public :
    virtual property int Slot {
        int get(){
            return -1;
        }
    }
};

ref class Weapon1 : masterWeapon{

public :
    virtual property int Slot{
//following like throw an error :  cannot override base class method 
        int get() override = masterWeapon::Slot::get{
            return 1;
        }
    }

};

只需删除 = masterWeapon::Slot::get 部分即可编译。如果您阅读 C3764 附带的错误消息，它会让这一点变得更加明显(但不是 100%):

...because the base method is explicitly overridden by 'Weapon1::Slot::get'

给我们以下代码:

ref class Weapon1 : masterWeapon{
public :
    virtual property int Slot {
        int get() override {
            return 1;
        }
    }
};

当遇到:

masterWeapon^ weapon1 = gcnew masterWeapon();
masterWeapon^ weapon2 = gcnew Weapon1();

Console::WriteLine(L"weapon1->Slot = {0}", weapon1->Slot);
Console::WriteLine(L"weapon2->Slot = {0}", weapon2->Slot);

结果:

weapon1->Slot = -1

weapon2->Slot = 1
