如何从JObject获取所有项目？

JObject jObject = new JObject();
jObject.Add("name", "John");
jObject.Add("age", 25);
jObject.Add("city", "New York");

IEnumerable<JProperty> properties = jObject.Properties();
foreach (JProperty property in properties)
{
    Console.WriteLine("Property Name: " + property.Name);
    Console.WriteLine("Property Value: " + property.Value);
}
