如何使用 Newtonsoft.Json 包在 C#(4.0) 中解析我的 json 字符串

I am new to JSON.In my asp.net application i want to parse the json string.So, i have used Newtonsoft.Json package for reading and writing json data.Now, i can able to parse the simple json data.But now i have received some complex json data for parsing.So, i little bit struck on it.

This is JSON Data:

    quizlist: [
     {
            QUIZ: {
                'QPROP': [

                                },
                                {

                                    'mark'  : '5',
                                    'hint': ''
                                },
                                {

                                    'answer': 'paradigmshift',
                                    'mark'  : '5',
                                    'hint': ''
                                },
                                {
                                    'questiontext': 'proportions',
                                    'penalty': '0.3333333',
                                    'qtype': 'shortanswer',
                                    'answer': 'fixed',
                                    'mark'  : '5',
                                    'hint': ''
                                }
                            ]
                        }
                    }
                ]
            }
        }
     ]
}

This is my C# Code :

dynamic dynObj = JsonConvert.DeserializeObject(jsonString);

            foreach (var data in dynObj.quizlist)
            {
                foreach (var data1 in data.QUIZ.QPROP)
                {
                    Response.Write("Name" + ":" + data1.name + "<br>");
                    Response.Write("Intro" + ":" + data1.intro + "<br>");
                    Response.Write("Timeopen" + ":" + data1.timeopen + "<br>");
                    Response.Write("Timeclose" + ":" + data1.timeclose + "<br>");
                    Response.Write("Timelimit" + ":" + data1.timelimit + "<br>");
                    Response.Write("Noofques" + ":" + data1.noofques + "<br>");
                }
              }

我可以解析QPROP数组对象中的noofques对象.现在必须解析数据.测验QPROP.问题QUEPROP数组对象也...

但我没能完全解析...

Please guide me to get out of this issue...
