อยากได้ตัวอย่างการ export to excel จาก sql server แบบวิธีอื่นๆ

    public void ExportToExcel(DataTable dt, string NameExcel)
    {
        if (dt.Rows.Count > 0)
        {
            string filename = NameExcel;
            System.IO.StringWriter tw = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
            DataGrid dgGrid = new DataGrid();
            dgGrid.DataSource = dt;
            dgGrid.DataBind();

            dgGrid.RenderControl(hw);

            Response.ContentType = "application/vnd.ms-excel";
            Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
            this.EnableViewState = false;
            Response.Write(tw.ToString());
            Response.End();
        }
    }
