I have a trial version of Resharper and it always suggests that I switch regular strings to verbatim strings. What is the difference?
A verbatim string is one that does not need to be escaped, like a filename:
string myFileName = "C:\\myfolder\\myfile.txt";
would be
string myFileName = @"C:\myfolder\myfile.txt";
The @ symbol means to read that string literally, and don't interpret control characters otherwise.
