看着头晕, 几句就搞定的事. 不知道你为什么写了这么多.        /// <summary>
        /// 对数据操作
        /// </summary>
        public enum Data_Operate {
            /// <summary>
            /// 加密
            /// </summary>
            Encryptor,
            /// <summary>
            /// 解密
            /// </summary>
            Decryptor
        }
        /// <summary>
        /// DEC 加密与解密
        /// </summary>
        /// <param name="QueryString">明文</param>
        /// <param name="dec_action">对数据操作</param>
        /// <returns>加密后密文(字节型)</returns>
        public byte[] DEC_Encrypt_Decrypt(byte[] QueryByte, Data_Operate data_operate) {
            using (DESCryptoServiceProvider des = new DESCryptoServiceProvider()) {
                des.Mode = CipherMode.CFB; //加密模式                //8个字节 加密对象的密钥
                des.Key = Encoding.ASCII.GetBytes("MyDESIV");
                //8个字节 初始化向量
                des.IV = Encoding.ASCII.GetBytes("MyDESIV");
                ICryptoTransform transform;                if (Data_Operate.Encryptor == data_operate)
                    transform = des.CreateEncryptor(); //加密
                else
                    transform = des.CreateDecryptor(); //解密                return transform.TransformFinalBlock(QueryByte, 0, QueryByte.Length);
            }
        }
