Regex for parsing image size

Question

0.00/5 (No votes)

I'm having a problem with creating a regular expression to parse a Size, except delimited by a comma.

Ex.

34,34 = success
34,34a = fail

I only want a match of two numbers, I've tried the regular expression

Regex.IsMatch(input, "([0-9],[0-9])");"

And almost works, but matches letters succeeding the second pair.

I've looked for examples, but most are in javascript and I've almost sure C#'s regex is different.
I also know there are alternatives to parsing a string into a Size, but I'm striving to find a working regex.

Best regards,

JavaScript

Regex.IsMatch(input, "([0-9],[0-9])");

This expression does find a match for [numeric],[numeric] inside a string but does nothing about the rest of the input...
so a1,2,b also considered valid.
You have to include the begin-end marks to tell that you are looking for a pair of numbers separated by comma and nothing more...

JavaScript

Regex.IsMatch(input, "^([0-9],[0-9])$");
