POST کردن آبجکت در Restful API

جواب رو پیدا کردم:


var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://plusserver.pluschap.com/plusservice/plustime/createplustime");

                    httpWebRequest.ContentType = "application/json";

                    httpWebRequest.Method = "POST";





                    int year = Convert.ToInt32(txtPlusTimeYear.Text.Trim());

                    int month = Convert.ToInt32(txtPlusTimeMonth.Text.Trim());

                    int day = Convert.ToInt32(txtPlusTimeDay.Text.Trim());

                    DateTime georgianDateTime = new DateTime(year, month, day, new System.Globalization.PersianCalendar());

                    //var dte = DateTime.ParseExact(georgianDateTime.ToShortDateSt  ring(), "Mmm dd, yyyy ", CultureInfo.InvariantCulture);

                    string dte = georgianDateTime.ToString("MMM dd, yyyy ");

                    String date = dte + txtPlusTimeHour.Text.Trim() + ":" + txtPlusTimeMinute.Text.Trim() + ":" + txtPlusTimeSecond.Text.Trim();

                    //pattern: Apr 25, 2019 05:37:25





                    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))

                    {

                        string json = "{"enable":"true","title":"" + date + "","registerdate":"2020-10-10","establishtime":"2020-10-10"}";





                        streamWriter.Write(json);

                        streamWriter.Flush();

                        streamWriter.Close();

                    }





                    var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();

                    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))

                    {

                        var result = streamReader.ReadToEnd();

                    }
