为什么.NET额外的斜杠添加到路径已经存在的斜线？ [英] Why does .NET add an additional slash to the already existent slashes in a path?

问题描述

我注意到，C＃增加了额外的斜线（ \\ ）为路径。考虑路径 C：\\测试。当我检查字符串文本Visualiser的这条道路，实际的字符串是 C：\\\\测试。

I've noticed that C# adds additional slashes (\) to paths. Consider the path C:\Test. When I inspect the string with this path in the text visualiser, the actual string is C:\\Test.

这是为什么？它混淆了我，因为有时我可能要拆分的路径了（使用 string.Split（）），但不得不怀疑要使用的字符串（一个或两个斜线）

Why is this? It confuses me, as sometimes I may want to split the path up (using string.Split()), but have to wonder which string to use (one or two slashes).

推荐答案

.NET是不添加任何东西到你这里的字符串。你的看到的是的调试器如何选择显示的字符串的效果。 C＃字符串可以重新在2形式psented $ P $

.Net is not adding anything to your string here. What your seeing is an effect of how the debugger chooses to display strings. C# strings can be represented in 2 forms

• 逐字字符串：使用 @ 标志pfixed $ P $而且无需Ò逃逸 \\\\ 字符


• 普通字符串：标准C风格的字符串，其中 \\\\ 字符需要逃避自己

• Verbatim Strings: Prefixed with an @ sign and removes the need o escape \\ characters
• Normal Strings: Standard C style strings where \\ characters need to escape themselves

调试器将显示一个字符串作为一个普通的字符串与逐字字符串。这只是显示的问题，不过，这并不影响它的潜在价值。

The debugger will display a string literal as a normal string vs. a verbatim string. It's just an issue of display though, it doesn't affect it's underlying value.
