What is so complicated about asking how to save records to the db and generate and send a pdf attachment via email?

1. you send the class to a function to write the data,
2. then send the class to a function to generate your pdf,
3. then send the class to a function to send the email.

Task, Async

public async Task<ActionResult> Test()
        {
            var parameters = new List<KeyValuePair<string, string>>
            {
                new KeyValuePair<string, string>("login", ""),
                new KeyValuePair<string, string>("password", ""),
            };

            var data = new FormUrlEncodedContent(parameters);

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://ekinobilet.ru/ekbs/upload.aspx");
            request.Method = "POST";

            byte[] dataArray = await data.ReadAsByteArrayAsync();
            request.ContentLength = dataArray.Length;
            request.ContentType = "application/x-www-form-urlencoded";

            var dataStream = await request.GetRequestStreamAsync();
            dataStream.Write(dataArray, 0, dataArray.Length);
            dataStream.Close();

            var resp = await request.GetResponseAsync();
            dataStream = resp.GetResponseStream();

            Stream receiveStream = resp.GetResponseStream();
            StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);
            var responseText = readStream.ReadToEnd();

            StringBuilder output = new StringBuilder();
            XmlReader reader = XmlReader.Create(new StringReader(responseText));
            {
                reader.ReadToFollowing("list");
                reader.MoveToFirstAttribute();
                string count = reader.Value;
                output.AppendLine(count);
                string size = reader.Value;
                output.AppendLine(size);
                string file = reader.Value;
                output.AppendLine(file);
                string name = reader.Value;
                output.AppendLine(name);
            }
            ViewBag.list = output.ToString();

            return View(responseText);

The challenge now is to send an xml file with an operating authorization that was above...

public class CatalogModel
{
  public int LocalCodeColumn { get; set; }
  public Dictionary<string, string> CustomerTypes { get; set; }
}

public ActionResult Index()
{
  CatalogModel m = new CatalogModel();
  m.CustomerTypes = SelectListHelper.Get_Customer_Types();

  return View(m);
}

public static Dictionary<string, string> Get_Customer_Types()
{
   return new Dictionary<string, string>
  {
    {"Private", "PRIVATE"},
    {"Public", "PUBLIC"},
    {"Both", "BOTH"}
  };
}

@Html.DropDownListFor(m => m.CustomerType, new SelectList(Model.select_customerType, "Value", "Key"), "-- Select Customer Type --", new { @class = "form-control" })

function Save()
{
var Employee = {  
fname: $("#fname").val(),
mname: $("#mname").val(),  
lname: $("#lname").val()
};  
$.ajax({

type:"post",
url:"write url of server method here",
data:JSON.stringify(Employee),
dataType:"json",
success:function(data){
alert("Data saved successfully !");
}
});

}
