Upload multiple files to database using HTML5 and ASP.Net 4.0

You must use FileUpload1.PostedFiles and it is available only in .Net 4.5 or higher

   HttpFileCollection hfc = Request.Files;
        for (int i = 0; i < hfc.Count; i++)
        {
            HttpPostedFile hpf = hfc[i];
            string filename = Path.GetFileName(hpf.FileName);
            string foldername =  "Yahoo";
            Directory.CreateDirectory("~/Webimage/"+foldername);
            hpf.SaveAs(Server.MapPath("~/Webimage/" + foldername + filename));
            SqlCommand cmd = new SqlCommand("Insert into Image(Imagename,Imagepath) values(@Imagename,@Imagepath)", conn);
            cmd.Parameters.AddWithValue("@ImagePath", "../Webimage/" + filename);
            cmd.Parameters.AddWithValue("@Imagename", filename);
            conn.Open();
            cmd.ExecuteNonQuery();
            conn.Close();
            
        }
