            public string AccountZip { get; set; }

I did regularexpression for Zip code validation I am getting this Error 开发者_运维问答Message

parsing "/(^\d{5}(-\d{4})?$/" - Not enough )'s.

Can any body help me out?

Your regex looks like it was pulled from a javascript sample. Try this:

@"^\d{5}(-\d{4})?$"

You need one more ( at the end as follows:

RegularExpression(@"/(^\d{5}(-\d{4})?)$/"

Great job @"\b(0?[0-9][0-9][0-9][0-9][0-9])\b" actually works and validates both numeric and length
