c# - Intresting behaviour of IPAddress.TryParse -


i'm using ipaddress.tryparse validate ip address, if use

if (ipaddress.tryparse("192.168.1.009", out ip)

it fails, but

if (ipaddress.tryparse("192.168.1.007", out ip)

passes. if last digit 8 or 9 fails on valid ip address.

i'm not sure work?

quick guess:

009 , 007 interpreted octal numbers, whereas 007 valid number in base-8 , 009 not.

try if (ipaddress.tryparse("192.168.1.9", out ip)) instead.
