Excel.ExcelHandler handler = new Excel.ExcelHandler(); handler.Open(this.filename); handler.Write("Informe", "E9", row.Fecha); handler.Close();
它工作正常…没有错误…但是当我尝试打开填充的xlsx，Excel表示它已损坏。 任何想法为什么？ 我失去了这个想法，任何帮助将大大apreciated。
问候。
尝试将XlFileFormat.xlWorkbookNormal更改为XlFileFormat.xlWorkbookDefault或xlOpenXMLWorkbook 。 看起来像文件保存为'XLS'格式，但'XLSX'扩展名。 因此，错误。
