        if (dtValues.Rows.Count > 0)
            System.Console.Clear();
        foreach (DataRow row in dtValues.Rows)
        {
            string mailname = Convert.ToString(row["row1"]);
            string mailemail = Convert.ToString(row["row2"]);
            string Code = Convert.ToString(row["row3"]);
            string Code_new = Code.Replace("\t", "");
            string Id = Convert.ToString(row["row4"]);
            string str = AppDomain.CurrentDomain.BaseDirectory;
            string image = str + "Codes\\" + Code_new + ".jpg";
            //string path = Microsoft.SqlServer.Server.MapPath("/HTMLPage.html");
            //string strPath = HttpContext.Current.Server.MapPath("~/HTML");

            //string body = string.Empty;
            StreamReader reader = new StreamReader("HTMLPage1.html");

It should add an attachment:

// Create file attachment
Attachment ImageAttachment = new Attachment(Server.MapPath(Convert.ToString(row["FilePath"])));

// Set the ContentId of the attachment, used in body HTML
ImageAttachment.ContentId = Convert.ToString(row["FileName"]);

// Add an image as file attachment
Msg.Attachments.Add(ImageAttachment);

this works only for a web application, and only if the file to attach is local to the web application itself: OP request seems more general – Gian Paolo Jan 09 '18 at 15:28

I am looking at your last edit and you`re trying to attache the body variable: **Attachment attachFile = new Attachment(body);** You should pass the path of a file here. – Bruno Quintella Jan 11 '18 at 13:49
