弗尤博客（五）

这一篇中，我实现了，登录和游客环境下，在首页中单击博文标题跳转到该篇博文，点击博文作者跳转到该作者博客首页，在我的博客中点击博文标题跳转到该篇博文。

这些跳转都是在同一个页面中实现的，我用母版页放个人博客的导航和公告。web页面放datalist实现博文的，由于不会后台调用datalist中的控件，更改不了textbox的大小，我把数据库更改了，数据库中有个单独存放博文摘要的，准备以后实现下自动选取摘要，所以我用了2个datalist来显示全博文，和详细博文，写到这我有个想法，把它换成两张表是不是可以更好的实现。

我通过3条if判断登录下和非登录下的情况的。

后面还用之前的方法跳转到发布和管理页面，但是这个在后台代码中要判断是否登录，没有登录的话需要登录。
