JObject 错误 "Property with the same name already exists on object"

JObject error "Property with the same name already exists on object"

一般来说,我使用 JSON.NET 将 JSON 反序列化为动态对象没有任何问题。但是下面的 JSON 导致了错误

Can not add property consent to Newtonsoft.Json.Linq.JObject. Property with the same name already exists on object.

我已经根据 JSONLint 检查了 JSON,它似乎有效。我在这里错过了什么?

代码

dynamic d = JObject.Parse(jsonString);

JSON
