Asp.net中DataTable导出到Excel的方法介绍

                curContext.Response.AddHeader("Content-Disposition", "attachment; filename=" + pFileName + ".xls");
                curContext.Response.ContentType = "application/vnd.ms-excel";
                strWriter = new System.IO.StringWriter();
                htmlWriter = new System.Web.UI.HtmlTextWriter(strWriter);

                // 为了解决dgData中可能进行了分页的情况，需要重新定义一个无分页的DataGrid
                dgExport = new System.Web.UI.WebControls.DataGrid();
                dgExport.DataSource = pData.DefaultView;
                dgExport.AllowPaging = false;
                dgExport.ShowHeader = false;//去掉标题
                dgExport.DataBind();

                string[] arrHeader = pHeader.Split('|');
                string strHeader = "<table border=\"1\" style=\"background-color:Gray;font-weight:bold;\"><tr>";
                foreach (string j in arrHeader)
                {
                    strHeader += "<td>" + j.ToString() + "</td>";
                }
                strHeader += "</tr></table>";
                // 返回客户端
                dgExport.RenderControl(htmlWriter);
                string strMeta = "<meta http-equiv=\"content-type\" content=\"application/ms-excel; charset=UTF-8\"/>";
                curContext.Response.Write(strMeta + strHeader + strWriter.ToString());
                curContext.Response.End();
