範例

下列程式碼範例會使用 Id 屬性來顯示 Excel 活頁簿中的快取資料物件名稱。

這個範例需要:

  • 主控台應用程式專案或其他非 Office 專案。

  • 下列組件的參考:

    • Microsoft.VisualStudio.Tools.Applications.ServerDocument.dll 和 Microsoft.VisualStudio.Tools.Applications.Runtime.dll (如果專案的目標是 .NET Framework 4)。

    • Microsoft.VisualStudio.Tools.Applications.ServerDocument.v10.0.dll 和 Microsoft.VisualStudio.Tools.Applications.Runtime.v9.0.dll (如果專案的目標是 .NET Framework 3.5)。

  • Microsoft.VisualStudio.Tools.ApplicationsMicrosoft.VisualStudio.Tools.Applications.Runtime 命名空間 (在程式碼檔最頂端) 的Imports (Visual Basic) 或 using (C#) 陳述式。
