asp.net - How to detect visitor country -

to detect visitor country see below code suggested in many forums, cant working.

modglobal.resolvecountry.threeletterisoregionname

on local machine correctly return computer retional settings region whereas on production server return usa.

i guess because function return envoirement regional settings (ie servers regional setting), can confirm this? , if true, best practice detecting visitors country in asp.net?

try this

dictionary<string,string> objdic = new dictionary<string,string>();  foreach (cultureinfo objcultureinfo in cultureinfo.getcultures(culturetypes.specificcultures)) { regioninfo objregioninfo = new regioninfo(objcultureinfo.name); if (!objdic.containskey(objregioninfo.englishname))   {       objdic.add(objregioninfo.englishname, objregioninfo.twoletterisoregionname.tolower());   } }  var obj = objdic.orderby(p => p.key ); foreach (keyvaluepair<string,string> val in obj) {   ddlcountries.items.add(new listitem(val.key, val.value)); } 

englishname return country name

from ip see
