新的Org.BouncyCastle.openssl.PemReader对象的ReadObject方法返回null

Question

我正在尝试创建X509Certificate2实例。代码如下：

public X509Certificate2 Get509Certificate()
    {   
        string certkey = "some cert key";
        string privatekey = "some private key";
        var cert = new X509Certificate2(Convert.FromBase64String(certkey));
        AsymmetricCipherKeyPair keyPair;
        using (TextReader reader = new StringReader(privatekey)) {
            keyPair = (AsymmetricCipherKeyPair)new PemReader(reader).ReadObject();
        }
        cert.PrivateKey = DotNetUtilities.ToRSA(keyPair.Private as RsaPrivateCrtKeyParameters);
        return cert;
    }

当我在线下面打电话

new PemReader(reader).ReadObject()

我得到null值。我无法弄清楚为什么它返回null。 我正在使用DotNetOpenAuth＆amp; BouncyCastle插件执行Oauth 1.0a。 我还在https://www.sslshopper.com/certificate-key-matcher.html验证了我的证书和私钥，并且它与
