C# '@' before a String

What's the @ in front of a string for .NET?

I found this in a C# study book

DirectoryInfo dir = new DirectoryInfo(key.Key.ToString() + @":\");

The book however did not explain what the '@' symbol was for. I tried searching MSDN C# Operators but its not listed there. I can guess that it allows the developer to not have to escape a '\' or does it allow to not have any escape sequences?

What is this for and why would I use @":\" instead of ":\\"?

Thanks for the help

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<Student> @class = new List<Student>();

Because when you have a long string with many \ you don't need to escape them all and the \n, \r and \f won't work too.
