加密PHP->；C#

我想将php代码转换为c代码：

PHP代码：

$key = "xxxxxxxxxxxx";
$message = "MY MESSAGE";

$iv_length = mcrypt_get_iv_size( MCRYPT_RIJNDAEL_256, MCRYPT_MODE_CFB );
$iv = mcrypt_create_iv( $iv_length, MCRYPT_RAND );
$encrypted = mcrypt_encrypt( MCRYPT_RIJNDAEL_256, $key, $message, MCRYPT_MODE_CFB, $iv );
$result = base64_encode( $iv . $encrypted );

C#代码：

但它不起作用。 php代码不接受来自C#的编码字符串

你能帮我吗

谢谢

Define“但它不起作用”。发生了什么。php不接受uncryptDefine的结果“但它不起作用”。发生了什么。php不接受uncrypt的结果

public static string Encrypt(string message, string key)
{
    var text = Encoding.Default.GetBytes(message);
    using (var aes = new RijndaelManaged())
    {
        aes.BlockSize = 256;
        aes.KeySize = 256;
        aes.Padding = PaddingMode.Zeros;
        aes.Mode = CipherMode.CFB;
        aes.GenerateIV();
        var encryptor = aes.CreateEncryptor(Encoding.Default.GetBytes(key), aes.IV);
        using (var ms = new MemoryStream())
        {
            using (var cs = new CryptoStream(ms, encryptor, CryptoStreamMode.Write))
            {
                cs.Write(text, 0, text.Length);
                cs.FlushFinalBlock();
            }
                var byteResult = new byte[aes.IV.Length + ms.ToArray().Length];
                Buffer.BlockCopy(aes.IV, 0, byteResult, 0, aes.IV.Length);
                Buffer.BlockCopy(ms.ToArray(), 0, byteResult, aes.IV.Length, ms.ToArray().Length);
                return Convert.ToBase64String(byteResult);
        }

    }
}
