如何导出.xlsx文件C＃ASP.NET MVCrazor

我想将数据导出到.xlsx文件，但我似乎只能导出到.xls 。

导出.xlsx文件最简单的方法是什么？

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文件 ：

  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()); } }
