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

问题描述

在C＃中编写文件路径时，我发现我可以写C：\或C：/，并获得相同的路径。推荐哪一个？我听说某个地方比使用\（以\作为转义的顺序）更为推荐。

解决方案

Windows支持两个路径分隔符，因此两者都可以工作，至少对于本地路径（/不适用于网络路径）。事实是，在Windows上使用工作但非标准的路径分隔符（/）没有实际的好处，特别是因为您可以使用逐字字符串文字：

  string path = @C：\//看ma，没有逃避
  

我可以看到使用/ separator的好处的唯一的情况是当你只使用相对路径，并且会使用Windows和Linux中的代码。那么你可以将../foo/bar/baz指向同一个目录。但即使在这种情况下，最好离开System.IO命名空间（ Path.DirectorySeparatorChar ， Path.Combine ）来处理这些问题。

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).

解决方案

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

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.
