MVC2与ExtJs TreePanel的checked关键字问题

[失去乐山贼]

MVC2可以把IList<T> 用JsonResult转换JSON数据，我要实现带复选框的Tree,参考地址http://www.mhzg.net/a/20114/20114212300174.html ； 现在我要动态生成JSON，而这个checked是C#的关键字。不能为属性，怎么办？

//实体
      public virtual int id { get; set; }

       public virtual string text { get; set; }

       public virtual bool leaf { get; set; }

       public virtual string cls { get; set; }

       public virtual IList<UnitType> children{get;set;} 

       public virtual bool Checked { get; set; } 

控制器：

 public JsonResult showTree() {
   IList<UnitType> types=GetTypes();
   return Json(types, JsonRequestBehavior.AllowGet);
 }

 var store = Ext.create('Ext.data.TreeStore', {
            proxy: {
                type: 'ajax',
                url: '<%= Url.Action("showTree", "Home")%>'//'/Data/check-nodes.json'
            },
            sorters: [{
                property: 'leaf',
                direction: 'ASC'
            }, {
                property: 'text',
                direction: 'ASC'
}]
            });
            var tree = Ext.create('Ext.tree.Panel', {
                store: store,
                rootVisible: false,
                useArrows: true,
                frame: true,
                title: 'Tree Panel',
                renderTo: 'tree-div',
                width: 289,
                height: 220 
                });
            });

extjs checked小写的会显示复选框。。
官网JSON：[{
"text": "To Do",
"cls": "folder",
"expanded": true,
"children": [{
"text": "Go jogging",
"id" : "3",
"leaf": true,
"checked": true
},{
"text": "Take a nap",
"leaf": true,
"id" : "4",
"checked": false
},{
"text": "Climb Everest",
"leaf": true,
"id" : "5",
"checked": false
}]
},{
"text": "Grocery List",
"cls": "folder",
"children": [{
"text": "Bananas",
"leaf": true,
"id" : "8",
"checked": false
},{
"text": "Milk",
"leaf": true,
"id" : "10",
"checked": false
},{
"text": "Cereal",
"leaf": true,
"id" : "15",
"checked": false
},{
"text": "Energy foods",
"cls": "folder",
"children": [{
"text": "Coffee",
"leaf": true,
"id" : "52",
"checked": false
},{
"text": "Red Bull",
"leaf": true,
"id" : "13",
"checked": false
}]
}]
},{
"text": "Remodel Project",
"cls": "folder",
"children": [{
"text": "Finish the budget",
"leaf": true,

"checked": false
},{

}]

extjs 认这个checked属性的，换了名字extjs就不认识了，首字母大写的也不行Checked，纠结..

恩,是的. @前缀可令关键字可编译

Keywords are predefined reserved identifiers that have special meanings to the compiler. They cannot be used as identifiers in your program unless they include @ as a prefix. For example, @if is a legal identifier but if is not because it is a keyword.

上午的时候想到@了,只是之前是在Razor中使用@前缀屏蔽关键字 把它当成Razor的语法了

顶起来，各位路过的大侠帮帮忙..谢谢啦。

纯粹帮顶起来

你用的vs 什么版本，如果支持匿名类型的话 可使用匿名类型来实现

[阿非]

匿名类型也不行。

你可以先用Checked 生成相应json串，然后Replace 成小写

之后不用ActionResult 用流来控制输出

关键字是可以用的 加上 @符号就ok了，哈哈。
