JObject、JArray对JSON操作

  增删改查：

var cardJson = "['身份证','银行卡','门禁卡']";
            var cardJArray = JArray.Parse(cardJson);
var p = new Person { Name="fan",Age=12,Dog=new Dog { Name="奶牛"} };

var pJson = JsonConvert.SerializeObject(p);
JObject jobj = JObject.Parse(pJson);
//添加属性

jobj["NickName"] = "fan";

jobj["Wifes"] = new JArray("rose", "lisa");

((JArray)jobj["Wifes"]).Add( "july");

jobj["Cards"] = cardJArray;

//修改属性

jobj["Name"] = "li";

jobj["Age"] = 9;

jobj["Dog"]["Name"] = "阿黄";

((JArray)jobj["Wifes"])[0] = "roses";

//插入属性

jobj.Property("Name").AddBeforeSelf(new JProperty("ID", 1));

//删除属性

jobj.Property("Age").Remove();

((JArray)jobj["Wifes"])[2].Remove();

//查找

//遍历属性

var props = jobj.Children().Values();

foreach (var prop in props)

{

if (!(prop is JObject) && !(prop is JArray))

{

Console.WriteLine(prop.ToString());

}

}

//遍历数组

var cardList = ((JArray)jobj["Cards"]);

foreach (var card in cardList)

{

Console.WriteLine(card.ToString());

}

//强类型读取

Console.WriteLine(jobj.Value<int>("ID"));

var p2 = jobj.ToString();

 

对象->JObject->JSON：

var json = new JObject(
        new JProperty("status", result.Status.ToString()),
        new JProperty("results", new JObject(result.Entries.Select(pair =>
            new JProperty(pair.Key, new JObject(
                new JProperty("status", pair.Value.Status.ToString()),
                new JProperty("description", pair.Value.Description),
                new JProperty("data", new JObject(pair.Value.Data.Select(
                    p => new JProperty(p.Key, p.Value))))))))));
var str = json.ToString();

 

JObject合并：

jObj.Merge(JObject.Parse(userTranslate.ValueJSON));

 

JObject查找：

jObject.SelectToken($".{path}");//根据路径查找
