help me Certificate Verification (C#)

[borovA]

I am trying to access an Web. The problem is that they
expect the client to submit a certificate. I can access the site from
my browser, but it always asks which certificate I want to use. How
can I do this in my code.

So far I can get the certificate. It's properly
formatted, and I can instantiate a X509Certificate object
with it. But I can't figure out how to add it to the Root
store, so it is trusted. Even if I add it to the Root
with IE, I still get the "The underlying connection was
closed: Could not establish trust relationship with remote
server." error message, when I connect to the HTTPS
resource via C#.

here is my code:

using System;
using System.IO;
using System.Net;
using System.Security .Cryptography.X 509Certificates ;

public class CertPolicy : ICertificatePol icy
{
public bool CheckValidation Result(ServiceP oint sp, X509Certificate cert,
WebRequest request, int problem)
{
return true;
}
}

public class CertTest
{

public static void Main()
{
try
{
HttpWebRequest objRequest =
(HttpWebRequest )WebRequest.Cre ate("https://myweb/");
objRequest.Meth od = "POST";
X509Certificate myCert =
X509Certificate .CreateFromCert File(@"d:\a\cer t.der");
X509Certificate Collection x509 = objRequest.Clie ntCertificates;
x509.Add (myCert);
objRequest.Clie ntCertificates. Add(myCert);
ServicePointMan ager.Certificat ePolicy = new CertPolicy();

HttpWebResponse objResponse = (HttpWebRespons e)objRequest.Ge tResponse();
}
catch( Exception e )
{
Console.WriteLi ne( e.ToString() );
}
}
}
Thanks for any help

}
}
Problem was trivial :-)

solution:
objRequest.Cont entLength = 0;
