C＃Response.ContentType在Excel中创build多个选项卡

我在C＃中生成一个Excel报表，并需要添加第二个选项卡到将包含参考数据的Excel文件。 如何在不使用ClosedXML的情况下实现这一目标？

Response.AddHeader("content-disposition", "attachment; filename=" + fname); Response.ContentType = "application/vnd.ms-excel"; var writer = new System.IO.StringWriter(); var htmlTextWriter = new HtmlTextWriter(writer); dataGrid.RenderControl(htmlTextWriter); Response.Write(writer.ToString()); Response.End();
