Difference between forward slash (/) and backslash:

Forward slash (/); backslash "\".

What is the difference between a forward slash and a backslash? After a period of understanding

DOS path:
E: \ development materials \ ASP. NET advanced development... this is the role of the backslash followed by the file name
CSC/T: Library/R: system. web. dll/out: D: \ customhandler. dll d: \ customerhandler. CS... this means that the forward slash is followed by a command whose dir parameter is a command.

Windows:
Backslash \, used to represent directories in windows.
Forward slash/, URL, URL address. Eg http://www.cnblogs.com/zuoguanglin/

In Asp.net:
"../" Indicates the parent directory of the current directory, that is, the parent directory of the current directory;
"/" Indicates the root directory of the website;

In addition, many users prefer to use "E: \ test. cs" to obtain the file path. In this case, an escape character error occurs.
Solution: @ "E: \ test. cs"
