问题描述

我有来自地址簿的导入yahoo联系人的以下代码，但是它只导入前30位联系人而不是所有联系人，所以帮我解决这个问题。

I have following code for import yahoo contacts from address book, but its import only top 30 contacts not all contacts, so help me to figure out this problem.

private const string _addressBookUrl =" http://address.mail.yahoo.com/allcontacts" ;;

        // private const string _addressBookUrl =" http：//address.yahoo.com/yab/us/Yahoo_ab.csv？loc = us& .rand = 1671497644& A = H& Yahoo_ab.csv" ;;

        private const string _authUrl =" https：//login.yahoo.com/config/login？" ;;

        private const string _loginPage =" https://login.yahoo.com/config/login" ;;

        private const string _userAgent =" Mozilla / 5.0（Windows; U; Windows NT 5.1; en-US; rv：1.8.1.3）Gecko / 20070309 Firefox / 2.0.0.3" ;;
