request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new System.Net.NetworkCredential(username, password);
request.EnableSsl = true;
X509Certificate cert = X509Certificate.CreateFromCertFile(certificate path);
X509CertificateCollection certCollection = new X509CertificateCollection();
certCollection.Add(cert);
request.ClientCertificates = certCollection;
StreamReader sourceStream = new StreamReader("localfile path to upload");
byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
