Why @ symbol is used in string

Why "@" symbol is used in Strings? The Wrong way of writng a string: string x="c:\abc\hello.txt"; The Right way of writing the above string: string x=@"c:\abc\hello.txt"; What is the difference between these two? When you are using "@" symbol, you mean that the text is just a literal. But if you dont use "@" symbol, in the above case, the BACKSLASH will be treated as ESCAPE SEQUENCEand it will create errrors.
