使用Ajax导出Excel

I have a this code for excel export from database using MVC.

This code working on Index view but if the code in different ActionResult with parameters ( ajax post data ) not working. I can get values using ajax, I can create DataTable from database, datatable can write to excel but not downloading.

Using ClosedXML for excel export.

What can I do for it ?

Thanks for your help.

 string constr =ConfigurationManager.ConnectionStrings["constr"].ConnectionString;

using (SqlConnection con = new SqlConnection(constr))
{
    using (SqlCommand cmd = new SqlCommand("SELECT * FROM Customers"))
    {
        using (SqlDataAdapter sda = new SqlDataAdapter())
        {
            cmd.Connection = con;
            sda.SelectCommand = cmd;
            using (DataTable dt = new DataTable())
            {
                sda.Fill(dt);
                using (XLWorkbook wb = new XLWorkbook())
                {
                    wb.Worksheets.Add(dt, "Customers");

                    Response.Clear();
                    Response.Buffer = true;
                    Response.Charset = "";
                    Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
                    Response.AddHeader("content-disposition", "attachment;filename=SqlExport.xlsx");
                    using (MemoryStream MyMemoryStream = new MemoryStream())
                    {
                        wb.SaveAs(MyMemoryStream);
                        MyMemoryStream.WriteTo(Response.OutputStream);
                        Response.Flush();
                        Response.End();
                    }
                }
            }
        }
    }
}
