What does “@” mean in C# [duplicate]

Answer 1

Before string it allows different string formating rules. You can't use backslash to specify special symbols and "" (double quotes become quotes). I find this format very useful for regular expressions

Example

Console.WriteLine(@"\n""\/a"); // outputs \n"\/a 
Console.WriteLine("\\n\"\"\\/a"); // outputs \n"\/a

You might also seen @ symbol before variable. In such case it allows using special C# keywords as variables.

Example:

var @switch = 1;
var @if = "test";
