C# 如何将json转换为本地数据库类属性

我有一个将json值转换为本地数据库类的问题 如果我使用list代替EntitySet，它可以正常工作

这是我的类属性

当我从代码转换下面的类时

HttpClient client = new HttpClient();
var data = await client.GetStringAsync("http://demo.com/wk/lg/initimeiNumber=911115000013916&tz=Asia/Kolkata");
Info_Entity = JsonConvert.DeserializeObject<Info>(data);

---

您没有传递用于反序列化的数组（如异常所述）。您传递的对象中包含数组，但不是实际数组。您需要传递json对象的taskarray属性

---

此外，您的Info类与您从服务器接收到的json不匹配。

您能告诉我们变量数据是什么样子的吗？您能告诉我们json吗。@guiomie，我使用了json格式我已经避免了这一点，使用sqlite请看我的问题
