if trying save them windows phone phonebook - there no way save contacts @ time.

you can save them 1 1, may use foreach

sample save contact:

var phonecalltask = new phonecalltask         {             displayname = contactname.text,             phonenumber = phonetext.text         };         phonecalltask.show();
