REGULAREXPRESSION - identify specific value(s) as INVALID

#1

Hey all,

I'm looking for some help on coding a validationexpression of regular
expression validation control in C#.

The problem is simple..and it would seem the solution likely is as well.
But I haven't come up with it.

I'd like to validatie a textbox entry.

The entry must be 6 digits. And must NOT equal any of the following four
values : 110500, 101100, 109900, 101007.

I've tried a number of things to no avail. So I won't limit any of your
collective potential solutions with the novice suggestions I've tried.

Thanks in advance!!

Use a negative look-ahead:

(?!110500)(?!101100)(?!109900)(?!101007)\d{6}
