SSL Peer Verification Problem

exceptions

Hi,

In my C# application, I got to call web service via https and perform peer verification using a ".crt" file. If I add request.ClientCertificates.Add(x5092Obj); then I get exception :

WEB Excep : The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
 STATUS = TrustFailure
 STACK =   at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context)
   at System.Net.HttpWebRequest.GetRequestStream()

If I add

ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(customXertificateValidation);

that returns true, then it works perfectly even if I remove the request.ClientCertificates.Add line.

If in any circumstances, I got to return true in ServerCertificateValidationCallback and without that request can't receive the client from server. If I add that the .crt file that I am suppossed to use makes no sense.

How do I use the .crt file and confirm that the certificate is valid ? Can any on help me out. I did lots of research on this but couldn't get things to its point. Now am in a hurry to solve the problem. Any help, guidance is highly appreciated.

Thanks
