问题描述：
后台，Actoin中我向ViewBage中加入了一个json
ViewBage.JsonDateMenu ="[{"id":2,"text":"菜单管理","state":"open","iconCls":null,"checked":true,"attributes":null,"children":[{"id":3,"text":"新建菜单 ","state":"open","iconCls":null,"checked":true,"attributes":null,"children":null},{"id":5,"text":"编辑菜单","state":"open","iconCls":null,"checked":true,"attributes":null,"children":null}]},{"id":4,"text":"角色权限管理","state":"open","iconCls":null,"checked":true,"attributes":null,"children":[{"id":6,"text":"新增角色","state":"open","iconCls":null,"checked":true,"attributes":null,"children":null}]}]" System.String
但是前台通过@ViewBage取到的值是这样的
[{"id":2,"text":"菜单管理","state":"open","iconCls":null,"checked":true,"attributes":null,"children":[{"id":3,"text":"新建菜单","state":"open","iconCls":null,"checked":true,"attributes":null,"children":null},{"id":5,"text":"编辑菜单","state":"open","iconCls":null,"checked":true,"attributes":null,"children":null}]},{"id":4,"text":"角色权限管理","state":"open","iconCls":null,"checked":true,"attributes":null,"children":[{"id":6,"text":"新增角色","state":"open","iconCls":null,"checked":true,"attributes":null,"children":null}]}]
很明显，双引号被编码了显示出来，这样很明显不是我们要的效果，我们要的是原样输出，
解决方案：
1. @MvcHtmlString.Create(@ViewBag.JsonDateMenu)，这样之后，一切正常了！,一般扩展HtmlHelp的时候返回MVCHtmlString 都是使用的这个方法
2. @Html.Raw(@ViewBag.JsonDateMenu) 后来，无意中发现了这个方法，一样解决了问题，个人这个方式更好，当然还可以直接人工代码解码
