我需要在配置文件中转义反斜杠吗? [英] Do I need to escape backslash in a config file?

问题描述

我有一个配置文件 myapp.exe.config.在文件中，我有一个以完整路径文件名作为值的属性.

I have a config file, myapp.exe.config. In the file I have an attribute with a fullpath filename as the value.

<add key="InfoFile" value="c:\temp\info.txt" />

如果我使用单反斜杠或双反斜杠似乎可以工作.也就是说，

It seems to work if I use a single or double backslash. That is,

<add key="InfoFile" value="c:\\temp\\info.txt" />

也有效.这样做的正确方法是什么?

works also. What is the correct way to do this?

推荐答案

你不需要那个.属性值内的任何内容都是字符数据.

You don't need that. Anything within an attribute value is character data.

由于您使用 C# 读取这些值，因此它们将被转义，就好像它们是代码中的文字路径字符串一样.

Since you're reading these values using C#, they'll get escaped as if they would be a literal path string in code.

无论如何，您可能想知道 C# 有 @ 运算符来声明逐字字符串，这意味着在代码中使用文字路径时不需要转义反斜杠:

Anyway, you might want to know that C# has @ operator to declare verbatim strings, meaning that you don't need to escape backslashes when using literal paths in code:

string somePath = @"C:\blah\blih\bluh.txt";
