1.現在的你是否還有夢想？

座在客廳的沙發上，戴著耳機，閉上眼睛，聽著那首我聽了上百遍的see you again，想著速度與激情的那群人，我很羨慕他們，一群志同道合的人在一起，干著一件大家都那么向往的事，夢想，感覺這兩個字離我越來越遠，太多世俗的東西，奪走了我們原有的天真，每天感覺除了上班，吃飯，睡覺，我感覺不到還有什么樂趣.

曾經也想自己寫一些東西，可惜能力不夠，一次偶然的機會，認識了敷衍不起，相見如故，一下子聊了很多，給我的印象是，大神級的人物，有想法，文藝青年，我談到了我想搞一個自己博客的想法。

說到這里，他比我還激動，曾幾何時，他也有這樣的想法，那時候也是能力不夠，現在終于有那么點能力了，說開始就開始，一開始的計劃是，每個星期更新一個模塊的東西，現在的情況是開源博客系統的基本原型都出來了，如果你心懷這樣的一個博客夢想，想寫一個真正屬于自己的博客系統，那么還猶豫什么，加入我們。

在此給出see you again百度音樂盒地址：http://music.baidu.com/song/s/4707e5121d80855c1d51b在你不忙的時候，靜下心來，聽聽音樂，音樂有的時候能帶給我們一種微妙的感覺。

送大家一句話：夢想是春天的綠，嬌嫩脆弱充滿新意；夢想是生命的水，給人希望潤物無聲；夢想是天邊的風，來去匆匆追之不及；夢想是凋零的葉，滋養大樹迎來新生。

3.開源博客框架說明

開發工具：vs2013+mssql+EF6.0

整個項目采用的 asp.net MVC4.0+EF6.0+經典的簡單三層

項目采用最經典的三層架構，其實博客系統用這個完全就夠用了，EF采用的是model frist,BLL層和DAL采用T4模板自動生成。下面是數據庫表的一些說明。

4.在這個項目中你能學到什么？

博客系統的中的亮點，在這里使用HtmlAgilityPack組件解析HTML網頁，我們只需要把我們的博客園的賬號在這里輸入就可以很快的把我們博客園中的文章備份過來。

其核心代碼如下：

        /// <summary>        /// 根據用戶導入cnblog數據        /// </summary>        /// <param name="userName"></param>        /// <returns></returns>        public string Import(string userName, string iszf, string isshowhome, string isshowmyhome)        {            int blosNumber = 0;
