C#实现序列化和反序列化

       从我们面试准备上面，我知道了一个知识点，就是我们vs提供的序列化方法有两个，一个叫二进制序列化，一个叫做xml序列化，下面我们说一下二进制序列化的C#实现：

反序列化：        

public static T Desrialize<T>(T obj, string str)
        {
            try
            {
                obj = default(T);
                IFormatter formatter = new BinaryFormatter();
                byte[] buffer = Convert.FromBase64String(str);
                MemoryStream stream = new MemoryStream(buffer);
                obj = (T)formatter.Deserialize(stream);
                stream.Flush();
                stream.Close();
            }
            catch (Exception ex)
            {
                //throw new Exception("反序列化失败,原因:" + ex.Message);
                return obj;
            }
            return obj;
        }

序列化：       

 public static string Serialize<T>(T obj)
        {
            try
            {
                IFormatter formatter = new BinaryFormatter();
                MemoryStream stream = new MemoryStream();
                formatter.Serialize(stream, obj);
                stream.Position = 0;
                byte[] buffer = new byte[stream.Length];
                stream.Read(buffer, 0, buffer.Length);
                stream.Flush();
                stream.Close();
                return Convert.ToBase64String(buffer);
            }
            catch (Exception ex)
            {
                throw new Exception("序列化失败,原因:" + ex.Message);
            }
        }

反序列化：

        public static T Desrialize<T>(T obj, string str)

        {

            try

            {

                obj = default(T);

                IFormatter formatter = new BinaryFormatter();

                byte[] buffer = Convert.FromBase64String(str);

                MemoryStream stream = new MemoryStream(buffer);

                obj = (T)formatter.Deserialize(stream);

                stream.Flush();

                stream.Close();

            }

            catch (Exception ex)

            {

                //throw new Exception("反序列化失败,原因:" + ex.Message);

                return obj;

            }

            return obj;

        }

序列化：

        public static string Serialize<T>(T obj)

        {

            try

            {

                IFormatter formatter = new BinaryFormatter();

                MemoryStream stream = new MemoryStream();

                formatter.Serialize(stream, obj);

                stream.Position = 0;

                byte[] buffer = new byte[stream.Length];

                stream.Read(buffer, 0, buffer.Length);

                stream.Flush();

                stream.Close();

                return Convert.ToBase64String(buffer);

            }

            catch (Exception ex)

            {

                throw new Exception("序列化失败,原因:" + ex.Message);

            }

        }
