Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[facebook.Program+RootObject]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly. To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be
我看了其他帖子。
我的 json 看起来像这样:
{"data":[{"target_id":9503123,"target_type":"user"}]}
最佳答案
为了清楚起见,除了@SLaks 的回答之外,这意味着您需要更改这一行:
List<RootObject> datalist = JsonConvert.DeserializeObject<List<RootObject>>(jsonstring);
到这样的事情:
RootObject datalist = JsonConvert.DeserializeObject<RootObject>(jsonstring);
关于c# - 无法将当前 JSON 对象(例如 {"name":"value"})反序列化为类型 'System.Collections.Generic.List` 1,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/21358493/
