c# - Validating Positive number with comma and period -

i need regular expression validation expression will

allow

• positive number(0-9)
• , , .

disallow

• letter(a-z)
• any other letter or symbol except . , ,

for example, on asp.net text box, if type anything@!#--, regular expression validation disallow it, if type 10.000,50 or 10,000.50 should allowed.

i've been trying use regex:

^\d+(\.\d\d)?$ 

but textbox must allow , symbol , tried using integer regex validation, did disallow if type string, disallow . , , symbol while should allow number(0-9) , . , , symbol

your regex be,

(?:\d|[,\.])+ 

or

^(?:\d|[,\.])+$ 

it matches 1 or more numbers or , or . 1 or more times.
