什么是.NET（C＃）的JSSE等价物？

Question

I'm working on an application using c#-4.0 and EntireX Broker 9.5.1 I'm attempting to convert to tpcip connections to use ssl. I was successful in upgrading my java code to do the same thing thanks to Java/ Software AGs use of jsse for handling the SSL/ceritificate validation. However, when connecting to the same server/port under .net I'm getting the following error:
02150403: Certificate expired or invalid

The error message sounds like it's communicating. So how can I get .Net to successfully validate the certificate?

PS: The certificate is signed by Verisign.

UPDATE:
Both IE and Firefox successfully connect on https://server.domain:port without throwing certificate errors. My application is actually connecting to ssl://server:port?verify_server=y
verify_server=n throws the same certificate error.

The certificate is not expired. The stack trace from the exception stops right at Broker.Logon(); .

at SoftwareAG.EntireX.NETWrapper.Runtime.Broker.Logon(String password)
at FAServer.EntireXDotNetClasses.EntireXWrapper.CreateBroker() in C:\\Users\\tfburton\\Documents\\Visual Studio 2010\\Projects\\NEW FADCOM\\FAServer\\EntireXDotNetClasses\\EntireXWrapper.cs:line 1302

UPDATE:
Here's how I'm creating my Broker object.

try
{
  Broker mybroker;
  try { mybroker = new Broker(BrokerName, BrokerUser); }
  catch (Exception e)
  {
     Utilities.LogEntry("Error Creating broker instance -- BEFORE LOGON. ", e, true);

     throw new WrapperException("Error Creating broker instance -- BEFORE LOGON. "
                               + Environment.NewLine + e.Message);
  }
  try //{ mybroker.Logon(BrokerPass); }
  {
     mybroker.Password = BrokerPass;
     mybroker.Logon();  //<-- stracktrace points here
  }
  catch (AccessViolationException ave)
  {
     Utilities.LogEntry("Error During Broker Logon.", ave, 
                        EventLogEntryType.Error);

     throw new WrapperException(ave); //wrap and duck
  }
}
catch ( Exception e )
{   
   Utilities.LogEntry("Error Creating broker instance. ", e, true);

   XException be = e as XException; 
   if ( null != be  ) //<-- resolves to true
   {
      String msg = "Certificate error connecting to: " + BrokerName;

      throw new WrapperException(msg, e);
   }
   throw new WrapperException( "Error Creating broker instance. " 
                             + Environment.NewLine + e.Message);  //<-- error caught and re-thrown here

}

Turns out I was barking up the wrong tree.

I'm not sure if .NET has an equivalent for JSSE.

My solution turned out to be a lot simpler, concatinate the root certs in a text file and add

trust_store=path\to\file\myrrootcerts.pem

as a parameter to the url aka

BROKER-ID
