(菜鸟要飞系列)四，基于Asp.Net MVC5的后台管理系统（zTree绑定Json数据生成树）

上一次老师让我们用递归将中国城市镇县四级联动显示在树上，那个时候就知道可以显示在zTree上，可是苦于对Json的不了解，对zTree的Api的不了解，一直没有做出来，只好将递归算法显示在了窗体上，见C# 使用winForm的TreeView显示中国城镇四级联动, 前几天老师终于将他以前做的zTree的例子给我研究，终于知道了怎么写了（哭瞎，好没有成就感），感觉网上这部分资源好少，有也是关于SqlServer用EntityFramework中数据上下文写的，由于老师不让用EntityFramework框架,(总是说Oracle的EntityFramework框架太差劲，总有一天我要看看到底是不是这样)，才让我花了好长时间都无结果，一看源码原来如此简单粗暴。

首先献上 zTree的html代码

因为我自己Oracle数据库中的建表sql,和数据sql找不到了，所以发了个上次做的那个Mysql数据库的城镇级联数据表，这里你将上述代码稍加修改即可，这里不再赘述。
