序列化简言之是这样一种能力：能够把复杂的对象(Object)变成某种格式的字符串(常见的格式有xml,string,二进制文件等)，这样可以方便的在各种系统中传输或交换(比喻socket编程中的数据包只能用byte[]传输)，接收方得到该字符串后，通过反序列化可以还原为复杂对象,进而调用对象的方法或属性 -- 跟反射有点沾边：）
这里先给出一个WinForm的序列化例子，功能为通过打开文件对话框选择一个文件后，构造一个复杂对象，然后序列化为二进制格式，得到该格式后，再反序列化(还原)为复杂对象

不过在Silverlight中，传统的序列化方式有很多被精减掉了（比如BinaryFormatter之类），唯一得以保存的只剩下System.Xml.Serialization，所以SL中只能通过xml来序列化对象(虽然xml序列化后的字节数相对Binary有点大，不过我们也别无选择)，另外有一点很让人不习惯的是，需要序列化的自定义类中，居然不需要加[Serializable],[DataMember]这类标记！（这一点让我郁闷了好久，还为此在网上疯狂的百度，google为啥sl中不识别Serializable）
1.先定义一个需要序列化的类
namespace
SerializeDemo
{
/// <summary>
聊天室消息对象
</summary>
public class ChatMessage
{
string SenderName { set ; get ; }
ReceiverName { MessageType Type { byte [] Body { enum MessageType {
txt,img,file,unkNown
}
}
}
{
/// <summary>
聊天室消息对象
</summary>
public class ChatMessage
{
string SenderName { set ; get ; }
ReceiverName { MessageType Type { byte [] Body { enum MessageType {
txt,img,file,unkNown
}
}
}
