It means to interpret the string literally (that is, you cannot escape any characters within the string if you use the @ prefix). It enhances readability in cases where it can be used.

For example, if you were working with a UNC path, this:

@"\\servername\share\folder"

is nicer than this:

"\\\\servername\\share\\folder"

Prefixing the string with an   indicates that it should be treated as a literal  i e  no escaping   For example if your string contains a path you would typically do this   string path    c   mypath  to  myfile txt     The   allows you to do this   string path     c  mypath to myfile txt     Notice the lack of double slashes  escaping

As a side note  you also should keep in mind that  escaping  means  using the back-slash as an indicator for special characters   You can put an end of line in a string doing that  for instance   String foo    Hello   There

It also means you can use reserved words as variable names  say you want a class named class   since class is a reserved word  you can instead call your class class   IList lt Student gt   class   new List lt Student gt
