嘗試挖掘json數據時出現以下錯誤。使用無效鍵值訪問JArray值
使用無效鍵值訪問JArray值：「RateInfos」。預期陣列位置索引。
任何人都可以請這個問題的幫助，我想獲得currentAllotment：3的價值，這是從json提供的底部15行。

一行代碼引發錯誤。
IList<JToken> rates = root["HotelListResponse"]["HotelList"]["HotelSummary"]["RateInfos"]["RateInfo"].Children().Values().ToList();
將不勝感激，如果有人也可以告訴我一個eaiser的方式比我正在做的深入到json數據。
感謝 喬治
好像它抱怨RateInfos是一個JArray你嘗試的IList率=根[「HotelListResponse」] [」 HotelList 「] [」 HotelSummary 「] [」 RateInfos 「] [0] [」 RateInfo「]兒童（）的值（）ToList（）。;當然，這隻會讓你獲得第一個RateInfo。至於更好的訪問數據的方式，我不知道類似xml的任何類型的後代類型對json的支持。 –

嗨cgotberg是的，試過了，我讀過的書以及我在網上閱讀的信息都說json數組被[]包圍，但沒有數據有方括號，所以它爲什麼會抱怨數組索引。我對切換回xml有認真的想法，對我來說這很容易 – CareerChange
再次看看JSON它可能是問題是你排除這一層層次結構RoomRateDetailsList：{RoomRateDetails：{。您可以嘗試使用IList rates = root [「HotelListResponse」] [「HotelList」] [「HotelSummary」] [「RoomRateDetailsList」] [「RoomRateDetails」] [「RateInfos」] [「RateInfo」]。Children（）。Values ）.ToList（）;理想情況下，這是一個非常複雜的對象，將其反序列化爲合適的對象。 –
