Question

i’m using C# and i’m trying to allow only alphabetical letters and spaces. my expression at the moment is:

string regex = '^[A-Za-z\s]{1,40}$'; 

my IDE says that \s is an ‘Unrecognized escape sequence’

what am i missing?

Answer 1

‘\’ is a c# escape character as well as a regex escape character. Try:

string regex = @'^[A-Za-z\s]{1,40}$';
