推荐答案

反斜线（\\）字符是用来指示其他特殊字符这样一个特殊的转义字符随着新线（ \\ n ），标签（ \\ t ）或引号（ \\）如果你要包括一个反斜杠字符本身，你需要两个反斜杠或使用 @ 逐字字符串：\\\\任务或 @\\任务。

The backslash ("\") character is a special escape character used to indicate other special characters such as new lines (\n), tabs (\t), or quotation marks (\"). If you want to include a backslash character itself, you need two backslashes or use the @ verbatim string: "\\Tasks" or @"\Tasks".

阅读 MSDN文档/ C＃规格其中讨论正在使用反斜杠字符和使用逐字字符串的转义字符的文字。

Read the MSDN documentation/C# Specification which discusses the characters that are escaped using the backslash character and the use of the verbatim string literal.

的一般的来讲，大多数C＃.NET开发人员倾向于构建文件时使用 @ 逐字字符串/文件夹的路径，因为它节省了他们的青睐不必编写双反斜杠所有的时间，他们可以直接复制/粘贴的路径，所以我会建议你在做同样的习惯得到的。

Generally speaking, most C# .NET developers tend to favour using the @ verbatim strings when building file/folder paths since it saves them from having to write double backslashes all the time and they can directly copy/paste the path, so I would suggest that you get in the habit of doing the same.

这一切都表示，在这种情况下，我真的建议你使用 Path.Combine 实用方法中的 @ lordkain的回答作为，那么你就不需要担心是否反斜线已经包含在路径和意外加倍向上的斜线或合并路径部件时完全忽略他们。

That all said, in this case, I would actually recommend you use the Path.Combine utility method as in @lordkain's answer as then you don't need to worry about whether backslashes are already included in the paths and accidentally doubling-up the slashes or omitting them altogether when combining parts of paths.
