[Not a questiob] Need Regex pattern for finding the mentioned words below in c#

Hi Bala,

Here is the regex for dollar symbol

^([0-9]{1,3}\$?)$ (dollar optional here)

If dollar mandatory at last with single appearance then use this

^([0-9]{1,3}\$)$ or ^([0-9]{1,3}\${1})$ (dollar mandatory here)

will allow 100$, 111$, 001$, 123$.

For indian currency you can try this

^(\₹[0-9]{1,3})$ (rupee symbol is mandatory and should appear at first character)

but its not working in Rubular regex tester[^]
Since ₹ does'nt have any description for it, its working in here.So I hope it would work for you also.

Hope this helps you a bit.

Regards,
RK
