您对此有何看法？

Hi,
I am extending standard IEnumerator, and I was just wondering what is the
best way to make enumarator safe? What do I mean by safe? Detect deletes and
all...
My idea is to have private Guid state field in the collection, and every
time something is inserted or deleted from the collection, I will just
change the guid. Enumerator will just have to compare the guid received in
the begging to the current one. If they are different, the collection has
changed.
What are your thought on this?
Thank you,
Sasha
推荐答案
Sasha，
听起来像是一个好主意，而且它也会快速简单。
你必须要记住的唯一事情是锁定收藏品或
而不是确保指导多线程正确访问。
希望这会有所帮助。

Sasha,
That sounds like a good idea, and it would be quick and easy as well.
The only things you have to keep in mind is to lock the collections or
rather make sure that the guid is accessed correctly by multiple threads.
Hope this helps.

为什么？
Why?
否则枚举器将具有逻辑性错误。
如果有人添加了一些内容，但我们已经通过了那个区域。我们将
错过一件物品......

Otherwise enumerator will have a logical error.
What if someone added some stuff, but we already passed that area. We will
miss one item...
Take Care,
