05/16/2015

符號瀏覽工具， 類別檢視， 物件瀏覽器， 呼叫瀏覽器和尋找符號結果，傳遞要求新資料至Visual Studio物件管理員。物件管理員尋找適當的程式庫，並要求新的符號的清單。藉由提供要求的資料，以回應的程式庫Visual Studio物件管理員，透過IVsSimpleObjectList2介面。 Visual Studio物件管理員會呼叫的方法， IVsSimpleObjectList2以取得資料的介面，並且用來填入或更新的符號瀏覽工具檢視。

文件庫時叫用的工具、該節點已展開，或重新整理檢視時，可能會收到資料的要求。第一次叫用符號瀏覽] 工具時，物件管理員會要求文件庫，以提供最上層的清單。當使用者展開清單] 節點時，則文件庫會提供一份該節點下的子系。每個物件管理員查詢包含感興趣的項目的索引。若要顯示新的清單，物件管理員就必須決定有多少項目，在清單中，項目、其名稱、存取範圍及其他屬性的型別。

注意事項
下列的 managed 程式碼範例將示範如何提供清單的符號，透過實作IVsSimpleObjectList2介面。物件管理員會呼叫這個介面中的方法，並使用取得的資料填入或更新的符號瀏覽工具。原生程式碼的符號提供者實作，使用IVsObjectList2介面。
