    Default date validation?

    How to write an IsDate function that actually checks for a particular date
    format?

    Using try-catch on Convert.ToDateTime(sDate) doesn't catch invalid entry
    (i.e. 5/2000).....I want the dates to be input as mm/dd/yyyy OR m/d/yyyy OR
    m/d/yy (etc.)....

    Any thoughts?

    Default Re: date validation?

    a regex would come in handy here [url]http://regexlib.com/[/url]
    or do a cheesy
    System.DateTime myDateTime = DateTime.Parse(testString);

    and check myDateTime for validity. I prefer regex though
