问:我面临以下大问题:

从时间到另一个我发现以下异常:

Base-64 char数组的长度无效

我使用加密和解密:

public static string Encrypt(string text)
        {

            try
            {
                key = Encoding.UTF8.GetBytes(stringKey.Substring(0, 8));
                DESCryptoServiceProvider des = new DESCryptoServiceProvider();
                Byte[] byteArray = Encoding.UTF8.GetBytes(text);
                MemoryStream memoryStream = new MemoryStream();
                CryptoStream cryptoStream = new CryptoStream(memoryStream,des.CreateEncryptor(key, IV), CryptoStreamMode.Write);
                cryptoStream.Write(byteArray, 0, byteArray.Length);
                cryptoStream.FlushFinalBlock();
                return Convert.ToBase64String(memoryStream.ToArray());
            }

            catch (Exception ex)
            {
              string message =  ex.Message;
            }

            return string.Empty;
        }



        public static string Decrypt(string text)
        {
            try
            {
                key = Encoding.UTF8.GetBytes(stringKey.Substring(0, 8));
                DESCryptoServiceProvider des = new DESCryptoServiceProvider();
                text = text.Replace(" ", "+")
                Byte[] …
