c#AES解密希伯来字母显示为问号

Question

我有一个包含希伯来字母的字符串,
在我打算解密加密字符串后,所有希伯来字母都显示为问号(如 - > ??? ?? ??????)

这些是我用来加密和解密的两种方法

 public static string Encrypt(string dectypted)
    {
        byte[] textbytes = ASCIIEncoding.ASCII.GetBytes(dectypted);
        AesCryptoServiceProvider encdec = new AesCryptoServiceProvider();
        encdec.BlockSize = 128;
        encdec.KeySize = 256;
        encdec.Key = ASCIIEncoding.ASCII.GetBytes(Key);
        encdec.IV = ASCIIEncoding.ASCII.GetBytes(IV);
        encdec.Padding = PaddingMode.PKCS7;
        encdec.Mode = CipherMode.CBC;

        ICryptoTransform icrypt = encdec.CreateEncryptor(encdec.Key, encdec.IV);

        byte[] enc = icrypt.TransformFinalBlock(textbytes, 0, textbytes.Length);
        icrypt.Dispose();

        return Convert.ToBase64String(enc) + Key;
    }

    public static string Decrypt(string enctypted)
    {
        byte[] encbytes = Convert.FromBase64String(enctypted);
        AesCryptoServiceProvider encdec = new AesCryptoServiceProvider();
        encdec.BlockSize = 128;
        encdec.KeySize = 256;
        encdec.Key = ASCIIEncoding.ASCII.GetBytes(Key);
        encdec.IV = ASCIIEncoding.ASCII.GetBytes(IV);
        encdec.Padding = PaddingMode.PKCS7;
        encdec.Mode = CipherMode.CBC;

        ICryptoTransform icrypt = encdec.CreateDecryptor(encdec.Key, encdec.IV);

        byte[] dec = icrypt.TransformFinalBlock(encbytes, 0, encbytes.Length);
        icrypt.Dispose();

        return ASCIIEncoding.ASCII.GetString(dec);
    }

有人可以告诉我有什么问题,为什么我会收到希伯来字母的问号？
提前致谢

ASCII不能代表希伯来字符.它只能代表一组有限的拉丁字符和符号.UTF8可能是您要使用的编码.更换你的使用ASCIIEncoding.ASCII有Encoding.UTF8.
