C ++虚拟（密封）函数 [英] C++ virtual (sealed) function

问题描述

我在我的C ++项目中使用dll中的类。一切正常，直到...

I am using classes from a dll in my C++ project. All is working fine, until...

当试图调用某个方法（在对象浏览器中列出）时，我得到一个错误，这种方法不是一个

When trying to call a certain method (listed in the object browser), I am getting an error that this method is not a member of the namespace.

调查后，我注意到这个方法被列为virtual void x（）sealed。

Upon investigation, I noticed that this method is listed as "virtual void x() sealed".

有没有办法调用这样的函数？

Is there a way to make a call to such a function?

For future reference, I just received a response from the enterprise library support team. They posted a link to the following:

托管C ++和IDisposable
我使用新的Managed C ++ / CLI语法编写一些代码，错误：

Managed C++ and IDisposable I'm writing some code using the new Managed C++/CLI syntax and I ran into this error:

错误C2039：'Dispose'：不是'System :: IDisposable'的成员

error C2039: 'Dispose' : is not a member of 'System::IDisposable'

我开始的代码是：

image->Dispose(); // image implements IDisposable

这给了我相同的编译器错误，所以我想要消除一个类/命名空间错误，所以我重写为这样：

which gave me the same compiler error, so I wanted to eliminate a class/namespace error so I rewrote it as this:

((IDisposable ^)image)->Dispose();

其中给出了上述错误。 Yikes！

Which gave the above error. Yikes!

这里是修复：

使用delete。托管C ++现在在终结器中隐藏Dispose（）。只需删除对象，它处理其余的。 Freaky。

use delete. Managed C++ now hides Dispose() inside the finalizer. Just delete the object, it handles the rest. Freaky.

这真的很有效！
