using System.Net;
...
 
   ServicePointManager.ServerCertificateValidationCallback =
      new RemoteCertificateValidationCallback
         (IgnoreCertificateErrorHandler);
...
private bool IgnoreCertificateErrorHandler
   (object sender,
   System.Security.Cryptography.X509Certificates.X509Certificate certificate,
   System.Security.Cryptography.X509Certificates.X509Chain chain,
   System.Net.Security.SslPolicyErrors sslPolicyErrors)
{
 
   return true;
}
