DESCryptoServiceProvider des = new DESCryptoServiceProvider();
des.Mode = CipherMode.ECB;
des.Padding = PaddingMode.Zeros;
byte[] inputByteArray = Encoding.Default.GetBytes(pToEncrypt);

MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(), CryptoStreamMode.Write);

//byte[] aa = ms.ToArray();
foreach (byte b in ms.ToArray())

ret.AppendFormat("{0:X2}", b);
}
ret.ToString();
ms.Close();
return ret.ToString();
}
数据为：string data = "49121205566404565800000000000000";加密密钥为： string key = "1472583690123456";
程序加密后为:"8A4173F15E02F37F7B51DDDD81E2C581”，第三方软件为："D9932D9DA4021B68EC91C730291EC88C"
问题是，加密之后的数据与第三方正式软件加密的数据不一样，这是为什么呢？
琢磨两天没找出问题，求大神赐教！
