尝试使用EPPlus读取.xls文件时出错

Question

以下代码适用于.xlsx,但它不适用于.xls.我收到此错误消息

无法打开包裹.包是一个OLE复合文档.如果这是加密包,请提供密码

码

string filepath = txtBrowse.Text;

FileStream stream = System.IO.File.Open(filepath, FileMode.Open, FileAccess.ReadWrite);
//1. Reading from a binary Excel file ('97-2003 format; *.xls)
IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);

FileInfo newFile = new FileInfo(filepath);

using (ExcelPackage package = new ExcelPackage(newFile))
{
    string sheetName = System.DateTime.Now.ToShortDateString();

    foreach (OfficeOpenXml.ExcelWorksheet sheet in package.Workbook.Worksheets)
    {
        // Check the name of the current sheet
        if (sheet.Name == sheetName)
        {
            package.Workbook.Worksheets.Delete(sheetName);
            break; // Exit the loop now
        }
    }

    ExcelWorksheet worksheet = package.Workbook.Worksheets.Add(System.DateTime.Now.ToShortDateString());
}

我该怎么做呢？

Answer 1

EPPlus不适用于XLS格式.只有XLSX.你需要找一个新的库.

Answer 2

我成功地使用了托尼的回答/sf/answers/1323324341/并简单地使用 Microsoft.Office.Interop.Excel 将其转换，然后仍然可以使用 epplus
