这是JSON数据:

    quizlist: [
     {
            QUIZ: {
                'QPROP': [
                    {
                        'name': 'FB',
                        'intro': '',

                        'timeclose': '1355733840',
                        'timelimit': '0',
                        'noofques': '5',
                        'QUESTION': {
                            'QUEPROP': [
                                {
                                    'questiontext': 'Scienceisbasedont',
                                    'penalty': '0.3333333',

                                },
                                {

                                    'penalty': '0.3333333',

                                    'hint': ''
                                },
                                {

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

这是我的C#代码:

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>");
                }
              }

我可以解析直到QPROP数组对象中的noofques对象.现在必须解析数据.QUIZ.QPROP.QUESTION.QUEPROP数组对象也可以...

I can able to parse until noofques object in QPROP array objects.Now have to parse data.QUIZ.QPROP.QUESTION.QUEPROP array objects also...

但是我无法完全解析...

But i failed to parse fully...

请指导我解决此问题...

推荐答案

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>");

        foreach (var queprop in data1.QUESTION.QUEPROP)
        {
            Response.Write("Questiontext" + ":" + queprop.questiontext  + "<br>");
            Response.Write("Mark" + ":" + queprop.mark  + "<br>");
        }
    }
}
