以下是我读取 Excel 文件的代码。
代码。
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");
当我运行这段代码时,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.
