IEnumerator:具有空的Dispose方法是否正常? [英] IEnumerator: Is it normal to have an empty Dispose method?

问题描述

我正在编写一个 IEnumerator<T> 类进行迭代一个 COM 集合，我是 IDisposable ，所以我需要实现Dispose方法.

I'm writing an IEnumerator<T> class to iterate over a COM collection I'm wrappering. I've noticed that IEnumerator<T> extends IDisposable, so I'm required to implement the Dispose method.

但是，我想不出要放在那里的任何东西，因为我只引用了该集合(我不想将其放置在的末尾)和一个int用于索引.将Dispose方法保留为空是否正常?

However, I can't think of anything I would put there, as I only have a reference to the collection (which I wouldn't want being disposed at the end of a foreach), and an int for the index. Is it normal to leave the Dispose method empty?

推荐答案

是的.

IEnumerator<T>实现IDisposable，以防您制作确实需要处理的枚举数.由于不需要处理大多数枚举数，因此该方法通常为空.

IEnumerator<T> implements IDisposable in case you make an enumerator that does need to be disposed. Since most enumerators don't need to be disposed, the method will usually be empty.

通过创建一个迭代器.
