一个把java翻译成C#的解码语句

[qwa]

public String encode(String pv, String uu)
throws SecurityException
{
MessageDigest digester = MessageDigest.getInstance("SHA-1");
byte value[];

digester.reset();
value = digester.digest(uu.getBytes());
digester.update(pv.getBytes());
value = digester.digest(value);

return new String(Base64.encodeBase64(value));
}
以上是java语句，想翻译成c#语句，不知道哪位能帮忙搞一个，谢谢了

public static string Encode(string pv, string uu)
{
    using (SHA1 sha1 = SHA1.Create())
    {
        byte[] bytes = Encoding.UTF8.GetBytes(pv + uu);
        return Convert.ToBase64String(sha1.ComputeHash(bytes));
    }
}

java中uu的摘要又被摘要了一次。换这个看看：

public static string Encode(string pv, string uu)
{
    using (SHA1 sha1 = SHA1.Create())
    {
        List<byte> bytes = new List<byte>();
        bytes.AddRange(Encoding.UTF8.GetBytes(pv));
        bytes.AddRange(sha1.ComputeHash(Encoding.UTF8.GetBytes(uu)));

        return Convert.ToBase64String(sha1.ComputeHash(bytes.ToArray()));
    }
}

very thanks 第二个是对的，谢谢
