Using / or \\ for folder paths in C#
提问by Dominic K
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).
在 C# 中编写文件路径时，我发现我可以编写类似“C:\”或“C:/”的内容并获得相同的路径。推荐哪一款？我在某处听说使用单个 / 比使用 \ （使用 \ 作为转义序列）更推荐。

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:
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：
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.
我可以看到使用 / 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，最好还是离开 System.IO 命名空间（Path.DirectorySeparatorChar、Path.Combine）来处理此类问题。

I write paths in C# like this:
我在 C# 中这样写路径：
@"C:\My\Path"
@"C:\我的\路径"
The @ character turns off \ escaping.
@ 字符关闭 \ 转义。

This isn't a C# issue - it's a Windows issue. Paths in Windows are normally shown with a backslash: C:. In my opinion, that's what you should use in C#. Use @"C:\" to prevent special handling of backslaash characters.
这不是 C# 问题 - 这是 Windows 问题。Windows 中的路径通常用反斜杠显示：C:。在我看来，这就是您应该在 C# 中使用的内容。使用@"C:\" 来防止对反斜杠字符的特殊处理。

Use Path.Combineand you don't need to worry about such semantics.
使用Path.Combine并且您无需担心此类语义。

Please use Path.DirectorySeparatorCharOR better, as Poita suggested use Path.Combine.
请使用Path.DirectorySeparatorChar或更好，因为 Poita 建议使用Path.Combine。
