Rule #44
Do you always make file paths @-quoted?

In C#, backslashes in strings are special characters used to produce "escape sequences", for example \r\n creates a line break inside the string. This means that if you want to put a backslash in a string you must escape it out by inserting two backslashes for every one, e.g. to represent C:\Temp\MyFile.txt you would use C:\\Temp\\MyFile.txt. This makes the file paths hard to read, and you can't copy and paste them out of the application.

By inserting an @ character in front of the string, e.g. @"C:\Temp\MyFile.txt", you can turn off escape sequences, making it behave like VB.NET. File paths should always be stored like this in strings.

We have a program called SSW Code Auditor to check for this rule.
