如何使用SelectToken从Json获取特定值

using Newtonsoft.Json.Linq;

// 假设有以下Json数据
string json = @"
{
  'name': 'John',
  'age': 30,
  'address': {
    'street': '123 Street',
    'city': 'New York'
  },
  'hobbies': ['reading', 'music']
}";

// 将Json数据解析为JObject对象
JObject obj = JObject.Parse(json);

// 使用SelectToken获取特定值
string name = (string)obj.SelectToken("name");
int age = (int)obj.SelectToken("age");
string street = (string)obj.SelectToken("address.street");
string[] hobbies = obj.SelectToken("hobbies").ToObject<string[]>();

// 打印获取到的值
Console.WriteLine("Name: " + name);
Console.WriteLine("Age: " + age);
Console.WriteLine("Street: " + street);
Console.WriteLine("Hobbies: " + string.Join(", ", hobbies));

Name: John
Age: 30
Street: 123 Street
Hobbies: reading, music
