I'm trying to come up with a Data Annotation regular expression to match the following formats.
34
38-30
100,25-30
4-5,5,1-5
Basically the expression should only allow numbers, -(dash) and ,(comma) in any order
I tried following but couldn't get it working.
[RegularExpression(@"(0-9 .&'-,]+)", ErrorMessage ="Lot numbers are invalid.")]
