Epplus没有阅读excel文件

Question

下面是我读取excel文件的代码.

码.

FileInfo newFile = new FileInfo("C:\\Excel\\SampleStockTakeExceptionReport.xls");
ExcelPackage pck = new ExcelPackage(newFile);
var ws = pck.Workbook.Worksheets.Add("Content");
ws.View.ShowGridLines = false;
ws.Cells["J12"].Value = "Test Write";
pck.Save();
System.Diagnostics.Process.Start("C:\\Excel\\SampleStockTakeExceptionReport.xls");

当我运行代码时,它会抛出一个运行时错误.

错误

System.Exception: Can not open the package. Package is an OLE compound document. If this is an encrypted package, please supply the password ---> System.IO.FileFormatException: File contains corrupted data.

感谢是否有人可以提供建议/帮助.谢谢.

据我所知,Epplus不处理.xls(BIFF8格式)文件.

它处理较新的.xlsx(Open Office Xml)格式.

您可以使用excellibrary,因为它适用于xls文件.
