Hi,

I know this isn't a C# group, but its just a quick one.

As a seasoned C++ developer I'm learning C# as I go along. What's the @
symbol for before a string?

eg:

FileInfo myFile = new FileInfo(@"c:\Temp\Test\readme.txt");

Why can't it just be:

FileInfo myFile = new FileInfo("c:\Temp\Test\readme.txt"); ?

Thanks

David

Because it escapes all the characters in the string. It couldn't be the
second example you gave, it would have to be:

FileInfo myFile = new FileInfo("c:\\Temp\\Test\\readme.txt");

S'ok- found out.

Its for treating the '\' marks as '\' marks, not leading characters.

It states the string is a literal, warts and all. Without the @, you are
accepting \ as an escape character.

Your second string would fail, as it is not escaping anything valid.
