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

问题描述

在C#中写文件路径时，我发现我可以写类似C:"或C:/"的东西并得到相同的路径.推荐哪一个?我在某处听说使用单个/比使用 (使用 作为转义序列)更推荐使用.

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

Windows 支持两种路径分隔符，因此两者都可以使用，至少对于本地路径(/不适用于网络路径).问题是在 Windows 上使用有效但非标准的路径分隔符 (/) 没有实际好处，特别是因为您可以使用逐字字符串文字:

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

我能看到使用/分隔符的唯一好处是当您仅使用相对路径并且将使用 Windows 和 Linux 中的代码时.然后你可以让../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) 处理此类问题.

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.
