在反序列化JObject中訪問屬性（Json.Net）

我使用Json.Net中的JObject（o）反序列化了如下所示的Json。我已經成功解決了一些屬性問題，例如o [「items」] [0] [「formattedURL」]，它工作正常。然而，我遇到了類似o [「queries」] [「nextPage」] [「startIndex」]的錯誤，我想返回'11'，但它會引發錯誤。我已經廣泛地尋找關於此的文檔，但沒有運氣。在反序列化JObject中訪問屬性（Json.Net）

尋找於JSON，nextPage是一個數組，但是設法調用等的對象，因此引發的錯誤。

執行像下面

o["queries"]["nextPage"][0]["startIndex"] 
       |  |____index of the array 
       |____________ Array type

這工作：串c = OJ1 [ 「查詢」] [ 「下一頁」] [0] [ 「的startIndex」]的ToString（）; –

Praveen：另一個問題。由於「nextPage」是一個數組，因爲這是第一個數組元素，是不是索引[0]與「startIndex」相同？我不確定[0]在做什麼;似乎多餘。 –
