C# 类的序列化和反序列化_ly.mds.interface.service.basedata.icartype__system

System.Runtime.Serialization.SerializationException”类型的未经处理的异常在 mscorlib.dll 中发生 

序列化 (Serialization)将对象的状态信息转换为可以存储或传输的形式的过程。在序列化期间，对象将其当前状态写入到临时或持久性存储区。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。（摘自百度百科）

   在很多通讯或者数据存储的过程中，都需要序列化和反序列化的过程。

　　在C#中，如果想要进行自定义类的序列化，只需要简单地在定义类的时候添加Serializable标签即可。如：

　　经常用到的序列化方式有两种：二进制和XML，分为由System.Runtime.Serialization.Formatters.Binary.BinaryFormatter和System.Xml.Serialization.XmlSerializer实现。

　　BinaryFormatter进行序列化和反序列化的时候，不会关心实际类型。但是XmlSerializer需要。

　　自己写的一个简单的序列化辅助类
