RSA PHP 转C#

现在我知道PHP中RSA的公钥和私钥，但貌似C#的RSA中用公钥加密的结果不一致，求指导怎么转，还有就是私钥的话C#还需要很多个其他因子. PHP中公钥格式： $pubKey = '-----BEGIN PUBLIC KEY----- UFOfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCivaicGCwPqH4cyy7S9DoN

现在我知道PHP中RSA的公钥和私钥，但貌似C#的RSA中用公钥加密的结果不一致，求指导怎么转，还有就是私钥的话C#还需要很多个其他因子.

PHP中公钥格式：

$pubKey = '-----BEGIN PUBLIC KEY-----

-----END PUBLIC KEY-----';

PHP私钥格式：

$priKey = '-----BEGIN RSA PRIVATE KEY-----

请问只知道PHP的公钥和私钥的情况下如何转成C#版的。
