.NET/C#- EPPLUS DEMO

  强大的导出EXCEL,比NPOI更好用,更强大,可惜只有4.0版本的。

  记录一下DEMO

                var sheet = p.Workbook.Worksheets.Add("My Sheet");

                //Cells的起始索引是1
                sheet.Cells[1, 1].Value = 1234.123;
                sheet.Cells[2, 1].Value = 1;
                sheet.Cells[3, 1].Value = 2;
                sheet.Cells[4, 1].Value = 3;

                sheet.Cells[1, 1].Style.Numberformat.Format = "#,##0.00";//这是保留两位小数


                var sheet2 = p.Workbook.Worksheets.Add("My Sheet2");
                sheet2.Cells[1, 1].Value = "jie";
                sheet2.Cells[2, 1].Value = "xiaom";
                sheet2.Cells[3, 1].Value = "ccx";
                sheet2.Cells[4, 1].Value = "zhangs";

                sheet2.Cells[1, 1].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;//水平居中
                sheet2.Cells[1, 1].Style.Font.Bold = true;//字体为粗体
                sheet2.Cells[1, 1].Style.Font.Size = 22;//字体大小


                p.SaveAs(new FileInfo(@"F:Tempoutput.xlsx"));

        public ActionResult ExportExcel()
