Need help with Regular Expression

[news.microsoft.com]

How do I set this expression up for either IS NULL or IS NOT NULL?

I am trying to check to see if an incoming string has either of the two
values.

new Regex(@"^([^<>=]*)\s*IS NULL\s*\s*IS NOT NULL\s*)$",
RegexOptions.Compiled | RegexOptions.IgnoreCase);



Thanks

Bill

Do you have any particular reason to use regular expressions here
instead of straight forward string comparisons?
