Escaping .NET regex pattern for javascript

Question

Is there any helper function in (ASP).NET library that properly escapes .NET regex patterns to be used in javascript? So that i don't need manually escape + quantifiers, etc. As far as i understand RegularExpressionAttribute from Data Annotations performs proper translation. Can i reuse it somehow?

Answer 1

Escape() is your friend:

string escapedInput = Regex.Escape(input);

Turns, for instance, "a+b" into "a\+b".
