c＃使用指定的公钥验证证书的签名

Question

我有1x X509Certificate2和一个Publickey（x509certificate_1） 现在我创建了一个新的X509Certificate2并尝试验证它。

Org.BouncyCastle.X509.X509Certificate x509certificate_11 = DotNetUtilities.FromX509Certificate(x509certificate_1);
Org.BouncyCastle.X509.X509Certificate x509certificate_22 = DotNetUtilities.FromX509Certificate(x509certificate_2);
x509certificate_22.Verify(x509certificate_11.GetPublicKey());

错误：提供的公钥不是证书签名

有人可以解释一下，如何验证我的x509certificate_2到x509certificate_1？
