when to use @ in c#?

Question

I use @ symbol with local path only, but when do I use @ exactly?

Answer 1

You use @ before strings to avoid having to escape special characters.

This from the MSDN:

The advantage of @-quoting is that escape sequences are not processed, which makes it easy to write, for example, a fully qualified file name:

@"c:\Docs\Source\a.txt" // rather than "c:\\Docs\\Source\\a.txt"
