c#序列化、反序列化執行個體

序列化就是将一個對象的狀态持久化，把目前對象的資訊儲存到檔案中，在需要時反序列化擷取該對象的資訊。

下面是序列化與反序列化的執行個體。

輸入如圖所示的資訊，點選輸出格式内的二進制格式按鈕，将輸入目前對象資訊的二進制格式檔案（預設儲存在目前工程的bin目錄下），在進行反序列化時，在反序列化框的TextBox内輸入binar.dat也就是已經輸出的檔案，點選二進制格式的反序列化按鈕即可獲得以上序列化後儲存的對象的資訊。

其他兩種格式的也類似。至于這三種序列化方式的差別及優缺點在下一篇日志中會用執行個體來描述的，現在先來了解如何将對象序列化吧。

下面是上圖對應得背景代碼：
