如何在c#中获取JSON值

Install-Package Newtonsoft.Json

using Newtonsoft.Json;
using System;

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

class Program
{
    static void Main()
    {
        string json = "{\"Name\":\"John\", \"Age\":30}";

        // 反序列化为Person对象
        Person person = JsonConvert.DeserializeObject<Person>(json);

        Console.WriteLine($"Name: {person.Name}, Age: {person.Age}");
    }
}

using System;
using System.Text.Json;

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

class Program
{
    static void Main()
    {
        string json = "{\"Name\":\"John\", \"Age\":30}";

        // 反序列化为Person对象
        Person person = JsonSerializer.Deserialize<Person>(json);

        Console.WriteLine($"Name: {person.Name}, Age: {person.Age}");
    }
}
