The @ symbol in front of some strings

I see this @ character a lot in front of C# strings. I searched the
documentation online but coult not come up with the page that explains
this symbol. What is it used for?

re: The @ symbol in front of some strings

A string prefixed with @ means the escape sequences do not get processed.

localPath = "c:\\test\\test.txt";

is the same as

localPath = @"c:\test\test.txt";

re: The @ symbol in front of some strings

The @ can also be used to escape a keyword so you can use it as an
identifier.

public void MyMethod(string @string) // You now have a variable
called string
{
//...
}

Now, whether you should ever actually do this is debatable at best. It's
useful for things like machine-generated code, where you might be generating
a class where parameter names are derived from a source that doesn't have
the same keywords as C# (i.e., xsd.exe).

re: The @ symbol in front of some strings

Using the "@" character in front of a string literal makes the string a
"Verbatim" Literal, instead of a "Regular" literal.

"Regular" literals need to use a backslash to escape, as for example in
a file path:

string filePath = "DirectoryA\\myfile.txt"

If you use the "@" character, you do not need to use escape characters,
as in:

string filePath = @"DirectoryA\myfile.txt"
