datatable中的数据用excel导出时出现问题

--------------------编程问答--------------------                 workBook.SaveAs(@"D:\mydate.xls,
                                xlApp.XlFileFormat.xlExcel8, //xlsx文件是XlFileFormat.xlExcel12
                                Missing.Value,
                                Missing.Value,
                                Missing.Value,
                                Missing.Value,
                                Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
                                Missing.Value,
                                Missing.Value,
                                Missing.Value,
                                Missing.Value,
                                Missing.Value); --------------------编程问答-------------------- 顶，应该把DATATABLE的数据，提前做合法性检查，然后再写XLS

补充：.NET技术 ,  C#
