本文看点：

  1.  看了BlogEngine.NET中的实现代码显然是没有使用BlogEngine.Core中提供的文件资源类库，本示例：提供了使用BlogEngine.Core文件资源库使用方法。

  2. 使用了baidu.flash.avatarMaker类库实现了在ASP.NET mvc中，实现图片截取，上传功能。

 

领悟：

  1. baidu的脚本现在做的很强大呀，特别是他的百度地图功能中的脚本相当有水平呀。

  2. 读开源程序，别人的思想真的让人感慨很多，比如：BlogEngine.Core中的文件资源库，功能实现的接口方法提供XML,UC,DB几种实现，可谓之功能强大了，接口类的命名实在是佩服，感觉像是在用Directory和File类一样。

 

希望给读者们提供更多帮助。
