终结器和析构函数，维基百科怎么说？ [英] Finalizers and destructors, what's Wikipedia saying?

问题描述

据我了解，有两个阵营涉及这个问题-第一个阵营认为终结器是C＃的析构函数。因此，他们认为这两件事是相同的。

As I understand there are two camps concerning this question - the first one thinks that finalizer is a destructor specific to C#. So they think that these two things are the same.

第二个阵营认为两者之间存在细微差异-用Wikipedia编写-术语析构函数通常用于意思是确定性地调用清除，而当垃圾收集器说运行它时，将运行 finalizer。

The second camp thinks that there's a slight difference - written in Wikipedia - "the term "destructor" is typically used to mean a deterministically-invoked cleanup, whereas a "finalizer" runs when the garbage collector says to run it."

但是让我为自己澄清一下。确定性调用清理？根据C＃规范和msdn的规定，析构函数不能被调用（它们将被自动调用）。可以自动调用它们的唯一情况是由垃圾收集器。

But let me clarify something for myself. Deterministically-invoked cleanup? In C# specification and msdn it's written that destructors cannot be invoked(they are invoked automatically). The only case when they may be invoked automatically is by garbage collector.

因此，我认为确定性调用的清理与垃圾回收器之间没有任何区别。

So I don't see any difference between deterministically-invoked cleanup and the case with the garbage collector.

是否这样？

推荐答案

在C＃中，终结器和析构函数是同一事物的不同名称。

In C# finalizer and destructor are different names for the same thing.

C＃语言规范（1.6.7.6）实际上将它们称为析构函数。但是，由于名称析构函数很容易被误认为是C ++对应词（与C＃中的析构函数完全不同），因此可以使用术语终结器代替。

The C# language specification (1.6.7.6) actually refers to these as Destructors. However, as the name destructor may easily be mistaken for the C++ counterpart(which is quite different from a destructor in C#) it makes sense to use the term finalizer instead.
