在開發(fā)中，有時(shí)候需要生成的Excel樣子比較復(fù)雜，如果用代碼形式去控制EXCEL比較繁瑣費(fèi)時(shí)，所以事先做好需要生成EXCEL的模板，再生成的時(shí)候往里面填充數(shù)據(jù)這樣子比較簡(jiǎn)便。

這里利用NPOI（鏈接：https://npoi.codeplex.com/）第三方東西來實(shí)現(xiàn)；

代碼如下：

                if (File.Exists(templateXlsPath))                {                    int i = 4, j = 4;                    using (FileStream file = new FileStream(templateXlsPath, FileMode.Open, Fileaccess.Read))                    {                        HSSFWorkbook _excel = new HSSFWorkbook(file);                        ISheet _sheetBasic = _excel.GetSheet(sheet_basicInfo.Replace("$", ""));                        ISheet _sheetStreatLamp = _excel.GetSheet(sheet_LampMoreLess.Replace("$", ""));                        file.Close();                        foreach (ExcelBasicInfo excelBasic in basicInfoList)                        {                            IRow _row = _sheetBasic.CreateRow(i);                            _row.CreateCell(0).SetCellValue(excelBasic.Number);
