Regular expression not working in c#

I want to match the following 2 patterns.

The regular expression I'm using is ^[0-9]{5}|[0-9]{5}.[0-9]{5}$. It is working for the first pattern but not the second. I have tested with Regex tester for .net and it is working. Can someone let me know what is wrong with my regex?

Try ^([0-9]{5}|[0-9]{5}\.[0-9]{5})$

Maybe you should use.

([0-9]{5})(\.[0-9]{5})*

You can test yours own regex expression in: https://regexr.com/

EDIT:

([0-9]{5})(\.[0-9]{5})|([0-9]{5})

I tested it and that did not actually work for me. You should specify that '.' is a literal.

This works:

([0-9]{5})(\.[0-9]{5})?
