在操作Excel时候一些特殊值的转换是在所难免的,下面就给出转换方法大同小异,代码如下:
HSSFWorkbook hssfWorkbook = new HSSFWorkbook(); ISheet sheet = hssfWorkbook.CreateSheet("Sheet1"); //设置第一列(Cell) 宽度 sheet.SetColumnWidth(0, 5000); //创建格式化 实例对象 IDataFormat format = hssfWorkbook.CreateDataFormat(); // 保留两位小数格式 // 创建一个单元格 "1.20" ICell cell = sheet.CreateRow(0).CreateCell(0); //设置单元格的值 cell.SetCellValue(1.2); ICellStyle cellStyle = hssfWorkbook.CreateCellStyle(); //格式化值 cellStyle.DataFormat = HSSFDataFormat.GetBuiltinFormat("0.00"); cell.CellStyle = cellStyle; //货币 "¥20,000" ICell cell2 = sheet.CreateRow(1).CreateCell(0); cell2.SetCellValue(20000); ICellStyle cellStyle2 = hssfWorkbook.CreateCellStyle(); cellStyle2.DataFormat = format.GetFormat("¥#,##0"); cell2.CellStyle = cellStyle2; //科学计数法 "3.15E+00" ICell cell3 = sheet.CreateRow(2).CreateCell(0); cell3.SetCellValue(3.151234); ICellStyle cellStyle3 = hssfWorkbook.CreateCellStyle(); cellStyle3.DataFormat = HSSFDataFormat.GetBuiltinFormat("0.00E+00"); cell3.CellStyle = cellStyle3; //百分比 "99.33%" ICell cell4 = sheet.CreateRow(3).CreateCell(0); cell4.SetCellValue(0.99333); ICellStyle cellStyle4 = hssfWorkbook.CreateCellStyle(); cellStyle4.DataFormat = HSSFDataFormat.GetBuiltinFormat("0.00%"); cell4.CellStyle = cellStyle4; //电话号码 "021-65881234" ICell cell5 = sheet.CreateRow(4).CreateCell(0); cell5.SetCellValue(02165881234); ICellStyle cellStyle5 = hssfWorkbook.CreateCellStyle(); cellStyle5.DataFormat = format.GetFormat("000-00000000"); cell5.CellStyle = cellStyle5; //金额大写 - 壹贰叁 元 ICell cell6 = sheet.CreateRow(5).CreateCell(0); cell6.SetCellValue(123); ICellStyle cellStyle6 = hssfWorkbook.CreateCellStyle(); cellStyle6.DataFormat = format.GetFormat("[DbNum2][$-804]0 元"); cell6.CellStyle = cellStyle6; //日期格式化 ICell cell7 = sheet.CreateRow(6).CreateCell(0); cell7.SetCellValue(new DateTime(2004, 5, 6)); ICellStyle cellStyle7 = hssfWorkbook.CreateCellStyle(); cellStyle7.DataFormat = format.GetFormat("yyyy年m月d日"); cell7.CellStyle = cellStyle7; //日期格式化 ICell cell8 = sheet.CreateRow(7).CreateCell(0); cell8.SetCellValue(new DateTime(2005, 11, 6)); ICellStyle cellStyle8 = hssfWorkbook.CreateCellStyle(); cellStyle8.DataFormat = format.GetFormat("yyyy年m月d日"); cell8.CellStyle = cellStyle8; FileStream file = new FileStream(@"test.xls", FileMode.Create); hssfWorkbook.Write(file); file.Close(); 转载自:http://www.cnblogs.com/Murray/archive/2015/01/20/4235601.html
