在.NET编程中，经常面向对象处理完以后要转换成另一种格式传输或存储，这种将对象转向其他数据格式的过程，即序列化(Serialization)。
当两个进程在进行远程通信时，彼此可以发送各种类型的数据。无论是何种类型的数据，都会以二进制序列的形式在网络上传送。发送方需要把这个对象转换为字节序列，才能在网络上传送；接收方则需要把字节序列再恢复为对象。把对象转换为字节序列的过程称为对象的序列化。把字节序列恢复为对象的过程称为对象的反序列化。说的再直接点，序列化的目的就是为了跨进程传递格式化数据1. 什么是序列化和反序列化？
序列化（Serialization）：序列化是将对象状态转换为可保持或传输的格式的过程。
反序列化(Deserialization) ：与序列化相对的是反序列化，它将流转换为对象。这两个过程结合起来，可以轻松地存储和传输数据。
在序列化期间，对象将其当前状态写入到临时或永久性存储区（存入文件中）。以后，可以通过从存储区中读取或反序列化对象的状态，重新创建该对象。以此达到面向对象中的永续生存。(这句话的意思也就是，用二进制的序列化的形式，将"资源"保存到磁盘文件里，磁盘不损坏，则资源就存在)
注意一下：[Serializable]标识
Serializable属性用来明确表示该类可以被序列化。
同样的，我们可以用NonSerializable属性用来明确表示类不能被序列化。
