爲什麼下面的代碼不覆蓋C++ CLI中的基類屬性？

Question

我是C＃程序員，不太瞭解C++。 任何想法，爲什麼我得到錯誤？

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; 
     } 
    } 

};

只要刪除= masterWeapon::Slot::get部分，它會編譯。如果你閱讀隨附C3764錯誤信息它使這一點更加明顯（但不是100％）：

...因爲基方法是通過'Weapon1::Slot::get'

明確覆蓋給我們下面的代碼：

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

，當針對其運行：

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

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

個

結果：

weapon1->插槽= -1

weapon2->插槽= 1
