有没有更简单的方法可以使用newtonsoft在下面的json中获取键名称值

using Newtonsoft.Json.Linq;

{
  "name": "John",
  "age": 30,
  "city": "New York"
}

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

JObject jsonObject = JObject.Parse(json);

foreach (var property in jsonObject.Properties())
{
    string key = property.Name;
    JToken value = property.Value;

    Console.WriteLine("Key: " + key);
    Console.WriteLine("Value: " + value);
}

Key: name
Value: John
Key: age
Value: 30
Key: city
Value: New York
