如何确定性地处置C＃中的托管C ++ / CLI对象？ [英] How can I deterministically dispose of a managed C++/CLI object from C#?

问题描述

我在C ++ / CLI程序集中有一个托管对象。作为C ++ / CLI，它通过其析构函数实现了Disposable模式（是的，我知道它与标准C ++析构函数不同）。从C ++ / CLI，我可以简单地删除对象。但是，我将此对象用作C＃类中的成员变量。

I have a managed object in a C++/CLI assembly. Being C++/CLI, it implements the Disposable pattern through its "destructor" (yes, I'm aware it's not the same as a standard C++ destructor). From C++/CLI, I would simply delete the object. However, I am using this object as a member variable in a C# class.

从我的C＃类中，我想调用Dispose（）的等效项。当我完成使用C ++ / CLI对象上的方法时。由于它是（并且必须是）该类的成员变量，因此不可能使用using（）块。据我所知，没有公开的方法可以直接，确定性地使用C ++ / CLI以外的语言来处理资源。我该如何完成呢？

From my C# class, then, I would like to call the equivalent of the Dispose() method on the C++/CLI object when I am finished using it. Since it is (and must be) a member variable of the class, utilizing a using() block is out of the question. As far as I can tell, there is no exposed method for direct, deterministic disposal of resources from a language other than C++/CLI. How can I accomplish this?

推荐答案

类似于C ++ / CLI析构函数的语法会自动实现 IDisposable ，但是这样做的方式与C＃的显式接口实现类似。这意味着您必须转换为 IDisposable 来访问 Dispose 方法：

The C++/CLI destructor-like syntax automatically implements IDisposable, but it does so in a manner similar to C#'s explicit interface implementation. This means you'll have to cast to IDisposable to access the Dispose method:

((IDisposable)obj).Dispose();
