        // Load the certificate into an X509Certificate object.
        X509Certificate cert = X509Certificate.CreateFromCertFile(Certificate);

        // Load the certificate into an X509Certificate object.
        X509Certificate certTwo = X509Certificate.CreateFromCertFile(OtherCertificate);

        // Get the value. 
        bool result = cert.Equals(certTwo);
