C# @ string meaning.

And now for a little string manipulation:

string initXML = @"<?xml version=""1.0"" ?><request company=""gnc"" auth=""{0}"" unit=""{1}"" code=""{2}"" />";

initXML = String.Format(initXML, authCode, location, passCode);

The difference between a regular and verbatim string expression:

Regular literal	Verbatim literal	Result
"Unplug1dot6"	@"Unplug1dot6"	Unplug1dot6
"Backslash: \\"	@"Backslash: \"	Backslash: \
"Quote: \""	@"Quote: """	Quote: "
"CRLF:\r\nPost CRLF"	@"CRLF: Post CRLF"	CRLF: Post CRLF
