为什么 .NET 会在路径中已经存在的斜杠上添加一个额外的斜杠? [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# 向路径添加了额外的斜线 ().考虑路径 C:Test.当我在文本可视化工具中检查带有此路径的字符串时，实际字符串是 C:\Test.

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?这让我很困惑，因为有时我可能想拆分路径(使用 string.Split())，但不得不想知道要使用哪个字符串(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 没有在此处向您的字符串添加任何内容.您所看到的是调试器选择显示字符串的方式的影响.C#字符串可以用2种形式表示

.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:以 @ 符号为前缀，无需转义 \ 字符
• 普通字符串:标准 C 样式字符串，其中 \ 字符需要自己转义

• 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

调试器会将字符串文字显示为普通字符串与逐字字符串.不过，这只是显示问题，不影响其潜在价值.

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.
