C# equivalent to Java RSA/ECB/OAEPWithSHA-256AndMGF1Padding

我正在尝试在Java中加密字符串并在C#中解密。我首先尝试使用 RSA/ECB/PKCS1PADDING，它就像一个魅力，但现在我试图切换到 OAEP 填充，但我无法让它工作。加密工作正常，但解密不行。我唯一更改的是 Java 中的算法名称，在 C# 中我更改了 rsa。解密（数据，真）从假到真。是否需要更多更改？

我得到的异常是"解码 OAEP 填充时出错"。

我的 Java 加密方法：

public byte[] rsaEncrypt(byte[] data) {
    byte[] cipherData;
    try {
        RSAPublicKeySpec keySpec = new RSAPublicKeySpec(pubMod, pubExp);
        KeyFactory fact = KeyFactory.getInstance("RSA");
        PublicKey pubKey = fact.generatePublic(keySpec);
        Cipher cipher = Cipher.getInstance("RSA/ECB/OAEPWithSHA-256AndMGF1Padding");
        cipher.init(Cipher.ENCRYPT_MODE, pubKey);
        cipherData = cipher.doFinal(data);
        return cipherData;
    } catch (NoSuchAlgorithmException | IllegalBlockSizeException | InvalidKeyException | InvalidKeySpecException | NoSuchPaddingException | BadPaddingException e) {
        e.printStackTrace();
    }
    return null;
}

我的 C# 解密方法：

private string RSADecrypt(byte[] data)
    {
        const string PrivateKey = *the key*;
        const int PROVIDER_RSA_FULL = 1;
        const string CONTAINER_NAME = "Tracker";
        CspParameters cspParams;
        cspParams = new CspParameters(PROVIDER_RSA_FULL);
        cspParams.KeyContainerName = CONTAINER_NAME;
        RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(cspParams);
        rsa.FromXmlString(PrivateKey);
        byte[] decrypted = rsa.Decrypt(data, true);
        String decryptedString = System.Text.Encoding.UTF8.GetString(decrypted);
        return decryptedString;
    }

using (RSA rsa = new RSACng())
{
    rsa.FromXmlString(privateKeyXml);
    byte[] decrypted = rsa.Decrypt(data, RSAEncryptionPadding.OaepSHA256);
    return Encoding.UTF8.GetString(decrypted);
}
