Question

在我的应用程序中，我需要创建一个包含几个组合的excel文件。我已经创建了它。

现在我必须从excel中读取这些组合的值。我找到了一个从excel Read From Excel

中读取的链接

但在我的代码中我找到了这个..

这是我的代码

Microsoft.Office.Interop.Excel.Application oXL = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel._Workbook oWB;
Microsoft.Office.Interop.Excel._Worksheet oSheet;
Microsoft.Office.Interop.Excel.Range oRng;

//Get a new workbook.
oWB = (Microsoft.Office.Interop.Excel._Workbook)(oXL.Workbooks.Open("C:\\TopicUpload_2017October14.xls"));
//3rd Sheet
oSheet = (Microsoft.Office.Interop.Excel._Worksheet) oWB.Sheets.get_Item(1);

 Microsoft.Office.Interop.Excel.DropDowns allDropDowns = oSheet.DropDowns(Type.Missing);
 Microsoft.Office.Interop.Excel.DropDown oneDropdown = allDropDowns.Item("2");

现在我怎么能得到这个下拉列表的选定文本..当我检查时我得到了

oneDropdown.ListCount = 5.0; // items count of second drop down, which is true

但无法获得选定的文字。

oneDropdown.Text
