        // 1、创建JavaScriptSerializer
        var serializer = new JavaScriptSerializer();

        // 2、序列化
        // 将对象转换为 JSON 字符串
        var serializedResult = serializer.Serialize(RegisteredUsers);

        // 将指定的 JSON 字符串转换为 T 类型的对象
        var deserializedResult = serializer.Deserialize<List<Person>>(serializedResult);
