问题描述
在Windows操作系统的文件路径中，单斜杠和双斜杠有什么区别？
What is the difference between single slash and double slash in file path for Windows operating system such as
c:\\Personal\MyFolder\\MyFile.jpg
和
c:\Personal\MyFolder\MyFile.jpg
如果我使用单斜线或双斜线，那是怎么回事，因为我已尝试将两个图像都存储在我的代码中（在webconfig文件中）并且它们都可以正常工作。
What if I use the single or double slash because I have tried both for storing images in my code (in webconfig file) and both of them work fine.
有什么区别吗？
推荐答案
Windows会忽略双反斜杠。因此，尽管使用 \ 的第二种语法是正确的，但您应该使用该语法，而使用 \\ 的第一种语法是正确的
Windows ignores double backslashes. So while the second syntax with \ is correct and you should use that one, the first with \\ works too.
唯一的例外是在表示UNC路径的路径的开始处使用双反斜杠。
请参见。
The only exception is double-backslash at the very beginning of a path that indicates a UNC path.
See Universal Naming Convention.
尽管请注意，在许多编程语言（如C，C ++，Java，C＃，Python，PHP，Perl）中，反斜杠用作在。因此，它需要自己进行转义（通常使用另一个反斜杠）。因此，在这些语言中，通常需要在字符串文字中使用双反斜杠以实际获取路径的单反斜杠。因此，例如在C＃中，以下字符串文字实际上被解释为 C：\Personal\MyFolder\MyFile.jpg ：
Though note that in many programming languages like C, C++, Java, C#, Python, PHP, Perl, a backslash works as an escape character in string literals. As such, it needs to be escaped itself (usually with another backslash). So in these languages, you usually need to use a double backslash in the string literal to actually get a single backslash for a path. So for example in C#, the following string literal is actually interpreted as C:\Personal\MyFolder\MyFile.jpg:
var path = "C:\\Personal\\MyFolder\\MyFile.jpg";
尽管有。例如，在C＃中，您可以使用以下语法获得相同的结果：
Though there are alternative syntaxes. For example in C#, you can use the following syntax with the same result:
var path = @"C:\Personal\MyFolder\MyFile.jpg";
