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?

I've not used it but msdn.microsoft.com/en-us/library/… may help. Looks like it should take any string from .NET and make it into a valid string in javascript (by escaping stuff, etc.). — Chris

Escape() is your friend:

string escapedInput = Regex.Escape(input);

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