问题描述

我在asp.net应用程序中导入了yahoo联系人。

但是在导入雅虎联系人的过程中，我觉得这样;



sans-serif; * font-size：small; * font：x-small ;}



我怎么能解决它？

我的代码是：
Yahoo!xtract.cs中的




公共类YahooExtract：IMailContactExtract

{



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



字符串名称;

字符串电子邮件;

推荐答案

我的猜测是你没有从雅虎正确导出联系人。您应该将联系人称为CSV（逗号分隔）。

My guess is that you didn''t export the contact properly from Yahoo. You should expert the contacts as CSV (comma separated).
