C# 字符串转json

你可以使用Newtonsoft.Json（即Json.NET）库来解析JSON字符串

using Newtonsoft.Json;
using System;
 
namespace JsonParsingExample
{
    class Program
    {
        static void Main(string[] args)
        {
            string json = "{\"Name\":\"John\", \"Age\":30}";
            dynamic data = JsonConvert.DeserializeObject(json);
 
            Console.WriteLine($"Name: {data.Name}");
            Console.WriteLine($"Age: {data.Age}");
        }
    }
}

或者绑定类显示

using Newtonsoft.Json;
using System;
 
namespace JsonParsingExample
{
    class Person
    {
        public string Name { get; set; }
        public int Age { get; set; }
    }
 
    class Program
    {
        static void Main(string[] args)
        {
            string json = "{\"Name\":\"John\", \"Age\":30}";
            Person person = JsonConvert.DeserializeObject<Person>(json);
 
            Console.WriteLine($"Name: {person.Name}");
            Console.WriteLine($"Age: {person.Age}");
        }
    }
}
