C#对象序列化和反序列化

网上找了一个关于序列化和压缩相关的方法,记录下来,以便日后用!

        #region 可序列化对象到byte数组的相互转换

        public static byte[] ObjectToByteArray(object o)
        {
            MemoryStream ms = new MemoryStream();
            BinaryFormatter bf = new BinaryFormatter();
            bf.Serialize(ms, o);
            ms.Close();
            return ms.ToArray();
        }

        /// <summary>

            BinaryFormatter bf = new BinaryFormatter();
            return bf.Deserialize(ms);
        }
