Question

我想将数据导出到.xlsx文件，但我似乎只能导出到.xls。

导出.xlsx文件的最简单方法是什么？

这是我用来导出到.xls文件的代码：

GridView gv = new GridView();
gv.DataSource = listCatalogue.ToList();
gv.DataBind();
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=Catalogue.xls");
Response.ContentType = "application/ms-excel";
Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gv.RenderControl(htw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();

您可以使用EPPlus等外部库。

取自EPPlus documentation：

 private void DumpExcel(DataTable tbl)
        {
            using (ExcelPackage pck = new ExcelPackage())
            {
                //Create the worksheet
                ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Demo");

                //Load the datatable into the sheet, starting from cell A1. Print the column names on row 1
                ws.Cells["A1"].LoadFromDataTable(tbl, true);

                //Format the header for column 1-3
                using (ExcelRange rng = ws.Cells["A1:C1"])
                {
                    rng.Style.Font.Bold = true;
                    rng.Style.Fill.PatternType = ExcelFillStyle.Solid;                      //Set Pattern for the background to Solid
                    rng.Style.Fill.BackgroundColor.SetColor(Color.FromArgb(79, 129, 189));  //Set color to dark blue
                    rng.Style.Font.Color.SetColor(Color.White);
                }

                //Example how to Format Column 1 as numeric 
                using (ExcelRange col = ws.Cells[2, 1, 2 + tbl.Rows.Count, 1])
                {
                    col.Style.Numberformat.Format = "#,##0.00";
                    col.Style.HorizontalAlignment = ExcelHorizontalAlignment.Right;
                }

                //Write it back to the client
                Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
                Response.AddHeader("content-disposition", "attachment;  filename=ExcelDemo.xlsx");
                Response.BinaryWrite(pck.GetAsByteArray());
            }
        }
