C# 解析 Json 字符串

使用C#解析Json字符串非常简单。Json字符串是一种轻量级的数据交换格式，它由键值对组成，并使用大括号包围。C#提供了Json.NET库，它是一个功能强大的Json处理库，可以方便地解析和操作Json数据。

csharp
using Newtonsoft.Json;
using System;
namespace JsonParsingExample
{
    class Program
    {
        static void Main(string[] args)
        {
            string json = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";
            dynamic data = JsonConvert.DeserializeObject(json);
            string name = data.name;
            int age = data.age;
            string city = data.city;
            Console.WriteLine("Name: " + name);
            Console.WriteLine("Age: " + age);
            Console.WriteLine("City: " + city);
        }
    }
}

csharp
using Newtonsoft.Json;
using System;
namespace JsonParsingExample
{
    class Person
    {
        public string Name { get; set; }
        public int Age { get; set; }
        public string City { get; set; }
    }
    class Program
    {
        static void Main(string[] args)
        {
            string json = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";
            Person person = JsonConvert.DeserializeObject(json);
            Console.WriteLine("Name: " + person.Name);
            Console.WriteLine("Age: " + person.Age);
            Console.WriteLine("City: " + person.City);
        }
    }
