C＃Response.ContentType在Excel中创建多个选项卡

Question

我在C＃中生成Excel报告，需要在Excel文件中添加第二个标签，其中包含参考数据。如何在不使用ClosedXML的情况下实现此目的？

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();
