RSA加解密相关问题

[cswdcswd]

目前正在做RSA加解密,有JAVA的例子,但是c#里面有很多东西都没有,请问C#里面对应的是什么.
JAVA中:
JCERSAPublicKey
RsaPublicKey

X509CertificateObject obj = (X509CertificateObject) o;
JCERSAPublicKey key = (JCERSAPublicKey)obj.getPublicKey();
RsaKeyParameters parameters = new RsaKeyParameters(false,key.getModulus(),getPublicExponent());


c#中对应的是什么?

我想要得到红字的那部分的参数,java是如上代码可以得到,c#如何得到.
RsaKeyParameters parameters = new RsaKeyParameters(false,key.getModulus(),getPublicExponent());
