Python RSA 加密如何转换为 C# 代码？

public static string GetRsaEncrypt(string rsaKey, string txt)
{
    // 公钥大素数
    BigInteger biE = BigInteger.Parse(rsaKey, NumberStyles.HexNumber);

    // 大整数 N
    BigInteger biN = BigInteger.Parse("10001", NumberStyles.HexNumber);

    byte[] publicKeyByte2 = biE.ToByteArray().Reverse().ToArray();
    byte[] exponentByte2 = biN.ToByteArray().Reverse().ToArray();

    using (var RSA = new RSACryptoServiceProvider())
    {
        var RSAKeyInfo = new RSAParameters
        {
            Modulus = publicKeyByte2,
            Exponent = exponentByte2
        };

        RSA.ImportParameters(RSAKeyInfo);
        byte[] passwordByte = Encoding.UTF8.GetBytes(txt);
        var encryptResult = RSA.Encrypt(passwordByte, RSAEncryptionPadding.Pkcs1);
        string encrypted = BitConverter.ToString(encryptResult).Replace("-", "");
        return encrypted;
    }
}
