考试，考试，还是考试！无聊透顶的考试！但是不考又不行的考试！为了那一张薄薄的纸！我又白白浪费的3年宝贵的时间！强烈建议教育改革！最近我快被考试折磨的不行了！多次想过来写一篇，可是一想到考试，整个心情都没有了！不抱怨了，奉献点真东西给观众。
最近我遇到朋友问我，如何动态的在现有的TreeView控件上添加节点的问题，我找到了一些国外的站点，的确有些参考的代码，但是写的都不是太详细。于是我稍微花了点时间，整理了下，就算是和我以前写的那篇呼应一下吧，不过这篇有点单薄，就一篇，但是实用！如果没有读过上一篇的，强烈建议读一读！上一篇的地址是：http://www.cnblogs.com/OceanChen/archive/2009/02/18/1393291.html， 不罗嗦了，上代码，
