在Mono上使用X509Certificate2 – 使用公钥和私钥加载？

现在，我尝试像这样实例化X509Certificate2：

cert = new X509Certificate2(Resources.cred); 

其中Resources.cred是表示.pfx文件的byte[] 。
这在Windows / .NET上完全正常。

但是，在Mono JIT编译器版本3.2.8（Debian 3.2.8 + dfsg-4ubuntu1） （Ubuntu Server 14.04 LTS上的Mono ）下运行相同的代码，我得到以下exception：

 System.TypeInitializationException: An exception was thrown by the type initializer for  ---> System.Security.Cryptography.CryptographicException: Unable to decode certificate. ---> System.Security.Cryptography.CryptographicException: Input data cannot be coded as a valid certificate. ---> System.Security.Cryptography.CryptographicException: Input data cannot be coded as a valid certificate. at Mono.Security.X509.X509Certificate.Parse (System.Byte[] data) [0x00000] in :0 --- End of inner exception stack trace --- at Mono.Security.X509.X509Certificate.Parse (System.Byte[] data) [0x00000] in :0 at Mono.Security.X509.X509Certificate..ctor (System.Byte[] data) [0x00000] in :0 at System.Security.Cryptography.X509Certificates.X509Certificate2.Import (System.Byte[] rawData, System.String password, X509KeyStorageFlags keyStorageFlags) [0x00000] in :0 --- End of inner exception stack trace --- at System.Security.Cryptography.X509Certificates.X509Certificate2.Import (System.Byte[] rawData, System.String password, X509KeyStorageFlags keyStorageFlags) [0x00000] in :0 at System.Security.Cryptography.X509Certificates.X509Certificate2..ctor (System.Byte[] rawData) [0x00000] in :0 --- End of relevant stack trace --- 

如果重要，该认证是与我自己的CA签署的，并用于原始RSA。

我有.pfx ， .cer和.pvk文件可用于此证书。
如何使用Mono下的私钥继续加载此证书？

 byte[] pkcs12 = ...; X509Certificate2 cert = X509Certificate2(pkcs12); 

 byte[] pkcs12 = ...; X509Certificate2 cert = X509Certificate2(pkcs12, string.Empty);
