Epplus桌面應用程序 - 無法確定域的標識

Question

我剛剛開始將我的Excel Interop代碼啓動到epplus中，並在savng excel文檔時做了它，但無法讀取現有文件。我搜索，但每個結果都與Web應用程序有關，我正在開發一個桌面應用程序。 我的代碼是如此簡單：

Dim File As FileInfo = New FileInfo(DosyaAd) 
Using package As New ExcelPackage(File) 
    Dim She As ExcelWorksheet 
    She = package.Workbook.Worksheets("BF") 
End using 

我在得到這個錯誤：她= package.Workbook.Worksheets（ 「BF」）

如果在Microsoft Office或通過製作了該工作簿互操作，工作簿可能包含EPPLus庫無法提供的功能，例如行和主題，以及列出的其他功能here。

我自己並沒有經歷過，但我從其他人那裏聽說，當工作表包含大量內容時會出現問題。
