确定两条路径是否相同 [英] Determining if two paths are the same
问题描述
你好，
给定两个相对或绝对格式的文件名，我需要确定它们是否指向同一个文件。虽然我可以简单地将每个传递给
" Path.GetFullPath（）"并比较结果，关于
案例的规则是什么。也就是说，如何判断本地文件系统是否是区分大小写的
。我不想假设Windows是目标操作系统
，即使它实际上也是如此。谢谢。
Hi there,
Given two file names in relative or absolute format, I need to determine if
they point to the same file. While I can simply pass each to
"Path.GetFullPath()" and compare the results, what is the rule regarding
case. That is, how do you determine whether the local file system is
case-sensitive or not. I don''t want to assume that Windows is the target OS
even though realistically it will be. Thanks.
推荐答案
Windows文件系统不区分大小写。 Unix和其他一些是
区分大小写。

我不知道（虽然这并不意味着它不存在）。如果存在一个
，在我看来它必须在某个组件中实际访问该文件。
实际访问该文件。喜欢获取所有文件
属性的东西，或打开文件或类似的东西。
那说，你应该记住，因为各种各样的方式
别名文件，即使根据简单的字符串路径不同
比较，无论你是否正确处理区分大小写，你，
仍可能有误报。你的目标听起来像是你只需要尝试，只要你不是100％重要，你总是得到
正确答案。

I don''t know of any (though that doesn''t mean it doesn''t exist). If one
exists, it seems to me that it would have to be in some component that
actually accesses the file. Like something that gets all of the file
properties, or opens the file, or something like that.
That said, you should probably keep in mind that because of various ways
to alias a file, even if the paths are different based on a simple string
comparison, whether you correctly deal with case-sensitivity or not, you
could still have false negatives. You goal sounds like something you
should only be trying if it''s not 100% important that you always get the
right answer.
