各种JSON格式数据

一、数组中有多个对象，对象中的字段是数组

[
  {
    "jingyesi": [
      "床前明月光",
      "疑是地上霜",
      "举头望明月",
      "低头思故乡"
    ]
  },
  {
    "youziyin": [
      "慈母手中线",
      "游子身上衣",
      "临行密密缝",
      "意恐迟迟归",
      "谁言寸草心",
      "报得三春晖"
    ]
  }
]

代码如下：

 //1.声明数组
 string[] arry1 = { "床前明月光", "疑是地上霜","举头望明月","低头思故乡"};
 //2、声明对象
 var obj1 = new JObject();
 //3、把数组加入对象中的字段
 obj1.Add("jingyesi",JArray.FromObject(arry1));

 string[] arry2 = {"慈母手中线","游子身上衣","临行密密缝","意恐迟迟归","谁言寸草心","报得三春晖"};
 var obj2 = new JObject();
 obj2.Add("youziyin",JArray.FromObject(arry2));
 //4.声明ogject的集合，把两个对象加入进去
 List<object> data = new List<object>() { obj1,obj2};

 Console.WriteLine(JArray.FromObject(data));

二、json数组中加入新项

1、数值型数组

 JArray a = new JArray() {"1","2","3" };
 a.Add("4");
 Console.WriteLine(a);

输出：

[
  "1",
  "2",
  "3",
  "4"
]

如果要加入新的数值型数组
比如加入b数组

JArray b = new JArray() {"4","5","6" };

可以遍历b，把一项一项加入a

 JArray a = new JArray() {"1","2","3" };
 JArray b = new JArray() { "4", "5", "6" };
 foreach (var s in b)
        {
           a.Add(s);
        }
 Console.WriteLine(a);

代码输出合并后的数组

[
  "1",
  "2",
  "3",
  "4",
  "5",
  "6"
]

2、对象型数组

 string json = "[{"Name" : "Jack", "Age" : 34},{"Name" : "Abel","Age":29}]";
 var a = JArray.Parse(json);
 var user = new
            {
                Name = "Lucy",
                Age = 18
            };
 a.Add(JObject.FromObject(user));
 Console.WriteLine(a);

输出：

[
  {
    "Name": "Jack",
    "Age": 34
  },
  {
    "Name": "Abel",
    "Age": 29
  },
  {
    "Name": "Lucy",
    "Age": 18
  }
]
