Test for integer

[Rob]

I have a 3 character string that I want to test to see if it is a positive
integer... I could test that each individual character is >=0 and <=9... is
there a better way ?

Is there an IsInteger() function ?

If you are using .NET 2.0, you may want to use 'Integer.TryParse'. In .NET
1.0/1.1 you can use 'Integer.Parse' + exception handling. Maybe using
'IsNumeric' is an option too.

Hmm, I have wondered for a long while why they didn't make a TryParse for
Integer...they did for Double...

You can read the historic reason for the existence Double.TryParse in
previous versions at:
