Question

Tests:

1              PASS
123,234        PASS 
123,435,       FAIL
1,             FAIL
124,dsds,33    FAIL
121,121,1212   PASS

So, you can have any amount of numbers.

Also, if it matters, i’m working in C#, and i plan to coerce a list of Int32’s out of the values (after it passes the regex).

What regex pattern can i use for this?

Answer 1

You can use the following regex:

^\d+(,\d+)*$

This will also allow leading zeroes, if that’s not what you want you can use

^(0|[1-9]\d+)(,(0|[1-9]\d+)*$
