PathCanonicalize相当于在C＃ [英] PathCanonicalize equivalent in C#

问题描述

什么是等价于 PathCanonicalize 在C＃？

使用：我需要带好猜两个文件路径是否引用相同的文件（没有磁盘访问）。我典型的做法已经把它扔通过像MakeAbsolute和PathCanonicalize几个过滤器，然后做一个区分大小写的比较。

Use: I need to take a good guess whether two file paths refer to the same file (without disk access). My typical approach has been throwing it through a few filters like MakeAbsolute and PathCanonicalize, and then do a case-insensitive comparison.

推荐答案

快速和肮脏的：

在过去，我已经创建了一个的从路径字符串的FileInfo 对象，然后使用FullName属性。这将删除所有..\的和.\年代

In the past I have created a FileInfo object from the path string and then used the FullName property. This removes all of the ..\'s and the .\'s.

当然，你可以互操作：

 [DllImport("shlwapi", EntryPoint="PathCanonicalize")]
    private static extern bool PathCanonicalize(
        StringBuilder lpszDst,
        string lpszSrc
    );
