c# - 将 JSON 对象反序列化为动态对象

Question

我有一个无法反序列化的 json 对象。json 对象来自Alpaca Markets api/snapshots。我正在使用 Refit，但能够创建一个类集来读取它，所以我已经直接读取了 json 对象，但无法使用 newtonsoft.json 库重新序列化它。这是json对象；

试试这个，它已经过测试并且工作正常（使用 newtonsoft.json 库）

var json=...your json string;

var jD = JsonConvert.DeserializeObject<Dictionary<string,Aapl>>(json);

json=JsonConvert.SerializeObject(jD);

输出
