c# - address validation global solution -

suppose user fillup form germany address country choose uk. how can validate address there if user choose country uk want user has write uk address other detail. how country. there ip available. need idea. thanks

without full details of formats of addresses of both countries (and if have support more, need details of each country), not able validate properly.

even detail, countries have such similar formats not able tell 1 address belongs to.

your best bet use address verification library/service.
