使用JArray和JObject操作JSON数据

一、JObject:json对象

1、创建一个json对象:

var obj = new JObject {{"Name", "Lucy" } };

控制台输出:

 

 解读:创建了一个json对象,字段是 Name,值是 Lucy

2、一个json对象中嵌套了子对象:

 var obj = new JObject { { "Name", "Lucy" } };
 var company = new JObject { { "Cmp", "上海网络有限公司" }, { "Tel", "0112-1263589" } };
 obj.Add("Company", company);
 Console.WriteLine(obj);

控制台输出:

 

 解读:创建一个json对象,有2个字段Name,Company

其中Company是一个对象

 

 

、JArray:json数组

1、创建一个json数组

 var jarray = new JArray();
 var lucy = new JObject { { "Name", "Lucy" }, { "Age", 18 } };
 var tom = new JObject { { "Name", "Tom" }, { "Age", 20 } };
 jarray.Add(lucy);
 jarray.Add(tom);
 Console.WriteLine(jarray);

控制台输出:

 

 解读:创建了一个json数组,包括了2个对象:每个对象都有2个字段:Name,Age

三、对象、数组混合使用

1、对象中有多个数组

  var obj = new JObject();
            var student = new JArray
        {
            new JObject {{ "Name", "Lucy" }, { "Age", 18 } },
            new JObject {{ "Name", "Tom" }, { "Age", 20 } }
        };
            var study= new JArray
        {
            new JObject {{ "Subject", "语文"}, { "Score", 100}},
            new JObject {{ "Subject", "数学" }, { "Score", 88}}
        };
            obj.Add("Student", student);
            obj.Add("Study", study);

            Console.WriteLine(obj);

控制台输出:

 

 解读:json对象有2个数组:Student,Study。数组分别有两个对象

2、对象中的字段值是一个数组

  var lucy = new JObject { { "Name", "Lucy" }, { "Age", 18 } };
  var study = new JArray
        {
            new JObject {{ "Subject", "语文"}, { "Score", 100}},
            new JObject {{ "Subject", "数学" }, { "Score", 88}}
        };
  lucy.Add("Study", study);
  Console.WriteLine(lucy);

控制台输出:

 

 解读:json对象的study字段是一个数组
