C# JObject将json字符串转为json对象

static void Main(string[] args)
        {
            string json = "{"name": "测试","mobile": "15341234699","city": {"province": "内蒙古自治区","city": "呼和浩特市","xian": "玉泉区" },"address": "255466" }";
            JObject jo = (JObject)JsonConvert.DeserializeObject(json.ToString());
            foreach (var item in jo)
            {
                Console.WriteLine($"{item.Key}:{item.Value}");
            }
            Console.WriteLine("Hello World!");
            Console.ReadKey();
        }
