如何将 Python RSA 加密代码转换为 C# 代码？

from rsa import key, common, transform, core, pkcs1

def get_rsa_encrypt(rsa_key, txt):
    pub_key = key.publickey(int(rsa_key, 16), 65537)
    key_length = common.byte_size(pub_key.n)
    padded = pkcs1._pad_for_encryption(txt, key_length)
    payload = transform.bytes2int(padded)
    encrypted = core.encrypt_int(payload, pub_key.e, pub_key.n)
    encode_str = hex(encrypted)[2:-1]
    if len(encode_str) % 2 != 0:
        encode_str = '0{}'.format(encode_str)
    return encode_str

//公钥大素数
            BigInteger biE = BigInteger.Parse(rsa_key, System.Globalization.NumberStyles.HexNumber);
            //大整数N
            BigInteger biN = BigInteger.Parse("10001", System.Globalization.NumberStyles.HexNumber);


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

            using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider())
            {
                RSAParameters RSAKeyInfo = new RSAParameters();
                UTF8Encoding ByteConverter = new UTF8Encoding();
                RSAKeyInfo.Modulus = publicKeyByte2.Reverse().ToArray();
                RSAKeyInfo.Exponent = exponentByte2.Reverse().ToArray();
                RSA.ImportParameters(RSAKeyInfo);
                byte[] passwordByte = ByteConverter.GetBytes(txt);
                var encryptReuslt = RSA.Encrypt(passwordByte, RSAEncryptionPadding.Pkcs1);
                //var Ciphertext = Convert.ToBase64String(encryptReuslt);
                encrypted = BitConverter.ToString(encryptReuslt).Replace("-", "");
                //encrypted = GetHexFromChs(Ciphertext);
            }
