解析json并搜索属性c#

using Newtonsoft.Json;

// JSON字符串
string json = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";

// 将JSON字符串解析为对象
var obj = JsonConvert.DeserializeObject(json);

// 搜索属性
var name = obj["name"];
var age = obj["age"];
var city = obj["city"];

using Newtonsoft.Json;

// 定义类来表示JSON的结构
public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string City { get; set; }
}

// JSON字符串
string json = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";

// 将JSON字符串解析为Person对象
var person = JsonConvert.DeserializeObject<Person>(json);

// 访问属性
var name = person.Name;
var age = person.Age;
var city = person.City;
