Postman's restsharp code snippet not working in winforms c#

Question

I have to send two parameters to a remote web service: firmaNo and irsaliyeData. firmaNo is numeric and irsaliyeData is a json object. I have already tried it with Postman and it worked without any problem. But i have to do it with a c# desktop application for my company.

I entered paramaters manually and send them to web service with Postman, server returned with a valid value. Postman generated the codes(c#-RestSharp) below:

var client = new RestClient("https://remoteserver.com/webservice");
var request = new RestRequest(Method.POST);

request.AddHeader("content-type", "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW");
request.AddParameter("multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW", "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"firmaNo\"\r\n\r\n2000007\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"irsaliyeData\"\r\n\r\n{   \"rampaNoktasi\": 21,   \"dosyaTarihi\": \"16.12.2016 17:37\"   }\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--", ParameterType.RequestBody);

IRestResponse response = client.Execute(request);

But when I copy and paste this code to my c# winform application's button click event handler, server always returns Time Out error.

var client = new RestClient("https://remoteserver.com/webservice");
var request = new RestRequest(Method.POST);

request.AddHeader("content-type", "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW");
request.AddParameter("multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW", "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"firmaNo\"\r\n\r\n2000007\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"irsaliyeData\"\r\n\r\n" + jsonstring + "\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--", ParameterType.RequestBody);

IRestResponse response = client.Execute(request);
lbl_result.Text = response.Content + response.ErrorMessage;

Do I have to add some code to the current cs file or app.config file. I am stuck at this point.

Thanks in advance.

I solved my problem by using WebClient method instead of RestSharp.

Thanks to everyone for help.
