无法在asp.net中的epplus上传.xls

Question

我有这个代码上传excel文件并将其放在gridview中：

protected void save_Click(object sender, EventArgs e)
    {
        try
        {
            string filename = Path.GetFileName(excelfileupload.FileName);
            excelfileupload.SaveAs(Server.MapPath("~/Uploader/") + filename);
            err.Text = "Upload status: File uploaded!";
            DataTable dt = getDataTableFromExcel(Server.MapPath("~/Uploader/") + filename);

        }
        catch (Exception ex)
        {
            err.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
        }
    }

    private DataTable getDataTableFromExcel(string path)
    { 
        using (var pck = new OfficeOpenXml.ExcelPackage())
        {
            using (var stream = File.OpenRead(path))
            {
                pck.Load(stream);
            }
            var ws = pck.Workbook.Worksheets.First();
            DataTable tbl = new DataTable();

            bool hasHeader = true; 
            foreach (var firstRowCell in ws.Cells[1, 1, 1, ws.Dimension.End.Column])
            {
                tbl.Columns.Add(hasHeader ? firstRowCell.Text : string.Format("Column {0}", firstRowCell.Start.Column));
            }
            var startRow = hasHeader ? 2 : 1;
            for (var rowNum = startRow; rowNum <= ws.Dimension.End.Row; rowNum++)
            {
                var wsRow = ws.Cells[rowNum, 1, rowNum, ws.Dimension.End.Column];
                var row = tbl.NewRow();
                foreach (var cell in wsRow)
                {
                    row[cell.Start.Column - 1] = cell.Text;
                }
                tbl.Rows.Add(row);
            }
            return tbl;
        }
    }

每件事都可以正常工作但是在上传文件.xls时它给了我一个错误：

Upload status: The file could not be uploaded. The following error occured: Can not open the package. Package is an OLE compound document. If this is an encrypted package, please supply the password

不知道它的意思，但是当它尝试将其转换为.xlsx时，它的工作正常而没有错误

如何解决？

如何解决？

不要使用XLS文件或不要使用EPPlus。

  

Create advanced Excel 2007/2010 spreadsheets on the server

     

EPPlus是一个.net库，使用Open Office Xml格式（xlsx）读取和写入 Excel 2007/2010文件

如果您需要打开XLS文件use JET or ACE。
