嗨,我使用 Microsoft.Office.Interop.Excel dll 编写了代码,但是当我发布我的网站时它不支持在线。然后我发现在线支持 EPPlus dll 女巫,但我在转换代码以使用这个新 dll 时遇到了麻烦。
使用 Interop.Excel 的旧代码:
using Excel = Microsoft.Office.Interop.Excel;
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet[] xlWorkSheet = new Excel.Worksheet[8];
public void ToSpreadSheet()
{
xlApp = new Excel.ApplicationClass();
xlWorkBook = xlApp.Workbooks.Open(tempFolderPathAlt + "dvforms\\InvestecTemplate.xlsx", 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
xlWorkSheet[0] = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
xlWorkSheet[1] = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(2);
xlWorkSheet[2] = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(3);
xlWorkSheet[3] = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(4);
xlWorkSheet[4] = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(5);
xlWorkSheet[5] = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(6);
xlWorkSheet[6] = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(7);
xlWorkSheet[7] = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(8);
}
这很好用,但现在我需要使用 EPPlus dll,但我遇到了问题。
using Excel = OfficeOpenXml;
Excel.ExcelPackage xlApp;
Excel.ExcelWorkbook xlWorkBook;
Excel.ExcelWorksheet[] xlWorkSeet = new Excel.ExcelWorksheet[8];
Stream stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(tempFolderPathAlt + "dvforms\\InvestecTemplate.xlsx");
Excel.ExcelPackage xlApp = new Excel.ExcelPackage(stream);
//This is where the problems begin, xlWorkBook.Worksheets.Add(1) is all underlined in red.
xlWorkSeet[0] = (Excel.ExcelWorksheet)xlWorkBook.Worksheets.Add(1);
如何从我的 Excel 模板加载工作表?我不确定我是否正确地完成了上述操作,请帮助我非常需要它。
提前致谢。
