求助，C# 处理json数据报错

求助，C# 处理json数据报错
这是闲的没事想用unity做一个天气预报的APP
在访问这个网址的时候出了一些问题
返回的JSON 数据是这样的

我使用了生成c#实体类

public List<Result> result { get; set; }
}

但是在使用以下代码转成 List<>的时候就报错了

var urladdress = "http://api.k780.com/?app=weather.future&weaid=1&appkey=42738&sign=8d01f34cb90f27f9f26a2bc6dce6fae5&format=json";
   Debug.Log("click");
   var data_weather = GetWebClient(urladdress);
   //Debug.Log(data_weather);
   List<Root> jobInfoList = Newtonsoft.Json.JsonConvert.DeserializeObject<List<Root>>(data_weather);

报错在 DeserializeObject

报错的提示是：
JsonSerializationException: Cannot deserialize JSON object into type 'System.Collections.Generic.List`1'.

不清楚是什么原因啊?
求指导！

是因为我没有对JSON 进行转义吗？

好的，我解决了
因为这个函数是不能嵌套的，
直接单独对resultitem部分进行解析就可以了

首先，你不该去c#交流区吗？

好像也没有 C# 的交流区。Windows程序设计，包括C#吧
