求C# 解析前台传来的json的方法
例如：
{
  "danju":[
{"itemsrc":"购进","happen":"2012-3-12","paymode":"现金","fapiao":"2012456322","shifu":"200","gongying":"诺基亚",passman:"经手人"}
],
"details":[
{"baseid":"12","price":"100","geshu":"2","inroom":"ruku gid","recnum":"20120308-4564","remark":"备注"},{"baseid":"13","price":"10","geshu":"20","inroom":"ruku gid","recnum":"20120308-4565","remark":"备注2"}
]
}

这样一个格式的json，想实现
danju的数据分离出来，对应的插入到sql 数据库，
details 分离出来，有几天，插入几条，我的例子就假设两条。
有什么比较好的方法吗？
