What is the @ for?

I have see code example such as this one

Directory.CreateDirectory(@dotnet.itags.org."\\machine\share");

What is that @dotnet.itags.org. for? What does it do?When you use @., escape sequences in string are not evaluated.

For example:

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

Here is about @. in the docs.

Directory.CreateDirectory(@."\\machine\share");

is equivalent to:

Directory.CreateDirectory("\\\\machine\\share");

Just as this

string myString = @."
a'b c d e
f""g";

is equivalent to:

string myString = "\na\'b c d e\nf\"g";

Just as he said, it helps to avoid escaping characters.
