Question

This is a .NET question for C# (or possibly VB.net), but I am trying to figure out what’s the difference between the following declarations:

string hello = 'hello'; 

vs.

string hello_alias = @'hello'; 

Printing out on the console makes no difference, the length properties are the same.

Answer 1

It marks the string as a verbatim string literal – anything in the string that would normally be interpreted as an escape sequence is ignored.

So 'C:\\Users\\Rich' is the same as @'C:\Users\Rich'

There is one exception: an escape sequence is needed for the double quote. To escape a double quote, you need to put two double quotes in a row. For instance, @'''' evaluates to '.
