似乎微不足道;如何解释“上次修改文件夹”？ [英] seems trivial; how to interpret "last time a folder was modified"?
问题描述
也许这是一种语言，因为英语不是我的第一语言。
Maybe it's a language thing, as english is not my first language.
这是否意味着文件夹本身被修改（即它被重命名等）或者可以我假设如果文件夹（或子文件夹）中的文件被修改，此文件夹属性将重置为当前时间？
Does it mean the folder itself was modified (ie. it was renamed etc.) or can I assume that if a file in the folder (or subfolder) was modified, this folder attribute gets reset to current time?
推荐答案
这不是语言问题。 它的英语含糊不清。
It's not a language thing. It's ambiguous in English.
这是语义辩论之一。 一些有文件夹的系统会说它是在文件夹本身被修改的时候，而其他人则认为文件夹本身并不是什么东西，实际上是其内容总和
的表示，因此对任何文件都有任何改变。文件夹中的项目构成对文件夹本身的更改。
This is one of those semantics debates. Some systems that have folders would say that it is when the folder itself was modified whereas other people would argue that a folder is nothing by itself and is in fact a representation of the sum of its contents and therefore any change to any item in the folder constitutes a change to the folder itself.
这就是为什么，由于它的错误，SharePoint对象模型使用了列表，它有两个字段：LastModified和ItemLastModified（或者类似的东西），消除了这个问题的歧义。
That's why, for its faults, the SharePoint Object Model got it right with lists, which have two fields: LastModified and ItemLastModified (or something like that), which disambiguate this issue.
我能给你的唯一建议就是为你编码的系统测试它，找出
The only advice I can give you is to test it for the system you're coding against and find out what that system does, because it could be either. Or both.
