不废话，直接贴代码

Windows的X509Certificate2 转BC的X509Certificate

<span style="white-space:pre">	</span>Org.BouncyCastle.X509.X509CertificateParser x509CertParser= new Org.BouncyCastle.X509.X509CertificateParser();
            
        X509ContentType x509Type =  X509ContentType.Cert;//到处cer格式的证书

            X509Certificate2 x509Cert2 = Key.GetCertificateFromStore("subjectname");
            

            Org.BouncyCastle.X509.X509Certificate x509bc;
            //System.Security.Cryptography.X509Certificates.X509Certificate2.Export();
            Org.BouncyCastle.X509.X509Certificate x509CertTest = x509CertParser.ReadCertificate(x509Cert2.Export(x509Type));

相反

<span style="white-space:pre">	</span>X509Certificate2 x509Cert3 = new X509Certificate2();
            
        x509Cert3.Import(x509CertTest.GetEncoded());//<span style="font-family: Arial, Helvetica, sans-serif;">x509CertTest 就是上面的bc中的</span><span style="font-family: Arial, Helvetica, sans-serif;">x509CertTest</span>

上面就完成了双方的互相转换
