最近我在codeplex上发了一个项目SmartObject（基于framework4.5,目前是1.0版本）.用法如下：

// HowToUse

using Spider.Data;

//json example from http://www.json.org/example.html

string json1 = @"{""widget"":

{""debug"": ""on"",

""window"":

{""title"": ""Sample Konfabulator Widget""",

""name"": ""main_window"",

""width"": 500,

""height"": 500

},

""p_w_picpath"":

{""src"": ""Images/Sun.png"",

""name"": ""sun1"",

""hOffset"": 250,

""vOffset"": 250,

""alignment"": ""center""},

""text"": {""data"": ""Click Here"",

""size"": 36.23,

""style"": ""bold"",

""name"": ""text1"",

""hOffset"": 250,

""vOffset"": 100,

""alignment"": ""center"", ""onMouseUp"": ""sun1.opacity = (sun1.opacity / 100) * 90;""}

}

} ";

string json2 = @"{""menu"":

{ ""id"": ""file"",

""value"": ""File"",

""popup"":

{""menuitem"": [{""value"": ""New"", "" 2},{""value"": ""Open"", "" 1.2},{""value"": ""Close"", "" 55555} ]

}

}

}";

dynamic o1 = SmartObject.Parse(json1);

dynamic o2 = SmartObject.Parse(json2);

Console.WriteLine(o1.widget.text.size);

Console.WriteLine(o1.widget.text[1]); Console.WriteLine(o1.widget.text["size"]);

Console.WriteLine(o1.ToJson());// ToJson return json string

Console.WriteLine(o2.ToJson());

dynamic o3=new SmartObject();

o3.A="abc";

o3["B"]=2345;

Console.WriteLine(o3.IsDefine("C"));

IDictionary<string, object> dict=o3.AsDictionary();

测试运行：
