MVC模式下的数据绑定
很怀念Webform下的基于模板的数据绑定。
查了下文档，HtmlHelper并没有相关的直接支持，需要自己在html里迭代生成数据列表。
既然HtmlHelper用的不是很爽，何必舍近求远，要知道ViewPage继承于Page的啊。对于View的局部使用webform的作法，有何不可呢？
[FileLevelControlBuilder(typeof(ViewPageControlBuilder))]
public class ViewPage : Page, IViewDataContainer
{
}
public class ViewPage : Page, IViewDataContainer
{
}
下边是测试代码：
Test1.aspx
