c#序列化、反序列化实例

序列化就是将一个对象的状态持久化，把当前对象的信息保存到文件中，在需要时反序列化获取该对象的信息。

下面是序列化与反序列化的实例。

输入如图所示的信息，点击输出格式内的二进制格式按钮，将输入当前对象信息的二进制格式文件（默认保存在当前工程的bin目录下），在进行反序列化时，在反序列化框的TextBox内输入binar.dat也就是已经输出的文件，点击二进制格式的反序列化按钮即可获得以上序列化后保存的对象的信息。

其他两种格式的也类似。至于这三种序列化方式的区别及优缺点在下一篇日志中会用实例来描述的，现在先来了解如何将对象序列化吧。

下面是上图对应得后台代码：
