使用/或\\在C＃中的文件夹路径 [英] Using / or \\ for folder paths in C#

问题描述

当在C＃编写的文件路径，我发现我可以写的东西，如C：\或C：/，并得到了相同的路径。哪一个建议？我听说的地方，使用的是单人/被推荐比使用更\（以\作为一个转义序列）。

When writing file paths in C#, I found that I can either write something like "C:\" or "C:/" and get the same path. Which one is recommended? I heard somewhere that using a single / was more recommended than using \ (with \ as an escaped sequence).

推荐答案

窗支持路径分隔符，所以两者将工作，至少在本地路径（/不会对网络路径工作）。问题是，没有在Windows上使用工作，但非标准路径分隔符（/）没有实际的好处，尤其是因为您可以使用逐字字符串：

Windows supports both path separators, so both will work, at least for local paths (/ won't work for network paths). The thing is that there is no actual benefit of using the working but non standard path separator (/) on Windows, especially because you can use the verbatim string literal:

string path = @"C:\"  //Look ma, no escape

在那里我可以看到使用/分离器的一个好处是，当你只有相对路径工作，将使用代码Windows和Linux的唯一情况。然后你就可以拥有../foo/bar/baz指向同一个目录下。但是，即使在这种情况下，最好是离开System.IO命名空间（ Path.DirectorySeparatorChar ， Path.Combine ）照顾等的问题。

The only case where I could see a benefit of using the / separator is when you'll work with relative paths only and will use the code in Windows and Linux. Then you can have "../foo/bar/baz" point to the same directory. But even in this case is better to leave the System.IO namespace (Path.DirectorySeparatorChar, Path.Combine) to take care of such issues.
