How to get key alias in a certificate

[leonard520]

I am able to parse the key alias from a certificate by keytool. However I don't know how to get it from X509Certificate2. Any one can suggest? Thanks.

─ keytool -list -v -keystore abc.pfx -storetype PKCS12
Enter keystore password:

Use another library to achieve it.
