HOW TO：取得伺服器總管的內建 SharePoint 節點資料

發行項
08/12/2011

針對 [伺服器總管] 的每一個內建 SharePoint 節點，您都可以取得節點所代表之基礎 SharePoint 元件的資料。如需詳細資訊，請參閱在伺服器總管中擴充 SharePoint 連線節點。

範例

下列程式碼範例示範如何取得 [伺服器總管] 中清單節點所代表之基礎 SharePoint 清單的資料。根據預設，清單節點具有一個 [在瀏覽器中檢視] 內容功能表項目，您可以按一下該項目來開啟 Web 瀏覽器中的清單。此範例藉由加入會在 Visual Studio 中直接開啟清單的 [在 Visual Studio 中檢視] 內容功能表項目，來擴充清單節點。程式碼會存取節點的清單資料，以取得 Visual Studio 中所開啟清單的 URL。

此範例會使用 SharePoint 專案服務來取得用於開啟 Visual Studio 中清單的 DTE 物件。如需 SharePoint 專案服務的詳細資訊，請參閱使用 SharePoint 專案服務。
