Newtonsoft.Json.JsonSerializationException Windows Phone 8

Question

获取并填充JSON数据时，我收到一个奇怪的错误：

  

“Newtonsoft.Json.JsonSerializationException”类型的例外   发生在Newtonsoft.Json.DLL但未在用户代码中处理

     

无法反序列化当前的JSON对象（例如{“name”：“value”}）   进入类型'WeatherApp.WeatherData + RootObject []'因为类型   需要一个JSON数组（例如[1,2,3]）才能正确反序列化。修理   此错误要么将JSON更改为JSON数组（例如[1,2,3]）或   更改反序列化类型，使其成为正常的.NET类型（例如   不是像整数这样的原始类型，不是像数组那样的集合类型   或者List）可以从JSON对象反序列化。   JsonObjectAttribute也可以添加到类型中以强制它   从JSON对象反序列化。 Path'coord'，第1行，第9位。

这是我的JSON课程：

我致电JsonConvert.DeserializeObject(Of RootObject())(content)，其中content是一个包含JSON data的字符串

非常感谢任何帮助。

Answer 1

更改

JsonConvert.DeserializeObject(Of RootObject())(content)

到

JsonConvert.DeserializeObject(Of RootObject)(content)

您要反序列化对象，而不是对象数组。
