直入主题，不废话...

1、JObject：基本的json对象

/// 
    /// Gets the j object.    /// 
    /// 
        public JObject GetJObject()    {        var obj = new JObject {
   {"Name", "Mark" } };        return obj;    }

2、JObject：嵌套子对象（JObject嵌JObject）

/// 
    /// Gets the j object.    /// 
    /// 
        public JObject GetJObject()    {        var obj = new JObject {
   {"Name", "Mark"}, {"Age", 8 }};        var info = new JObject {
   {"Phone", "132****7777"}, {"Gender", "男"}};        obj.Add("Info", info);        return obj;    }

3、JArray：基本json对象中的数组

/// 
    /// Gets the j array.    /// 
    /// 
        public JArray GetJArray()    {        var jarray = new JArray();        var mark = new JObject { { "Name", "Mark" }, { "Age", 8 } };        var jack = new JObject { { "Name", "Jack" }, { "Age", 9 } };        jarray.Add(mark);        jarray.Add(jack);        return jarray;    }

4、JArray： 多个json对象数组

/// 
    /// Gets the j array.    /// 
    /// 
        public JObject GetJArray()    {        var obj = new JObject();        var student = new JArray        {            new JObject {
   { "Name", "Mark" }, { "Age", 8 } },            new JObject {
   { "Name", "Jack" }, { "Age", 9 } }        };        var results = new JArray        {            new JObject {
   { "Subject", "语文"}, { "Score", 100}},            new JObject {
   { "Subject", "数学" }, { "Score", 88}}        };        obj.Add("Student", student);        obj.Add("Results", results);        return obj;    }

5、JArray：json数组嵌套数组（一个学生对应多个课程分数）

/// 
    /// Gets the results.    /// 
    /// 
        public JObject GetResults()    {        var mark = new JObject { { "Name", "Mark" }, { "Age", "8" } };        var results = new JArray        {            new JObject {
   { "Subject", "语文"}, { "Score", 100}},            new JObject {
   { "Subject", "数学" }, { "Score", 88}}        };                    mark.Add("Results", results);        return mark;    }

总结：写接口的时候，类似上面的5种情况经常会遇到，有时候会弄糊涂，算一次简单的复习吧。
