不同于TList类，TObjectList类的Add, Remove, IndexOf, Insert等方法都需要传递TObject对象作为参数，由于有了编译期的强类型检查，使得TObjectList比TList更适合保存对象。此外TObjectList对象有OwnsObjects属性。当设定为True (默认值)，同TList类不同，TObjectList对象将销毁任何从列表中删除的对象。无论是调用Delete, Remove, Clear 方法，还是释放TObjectList对象，都将销毁列表中的对象。有了TObjectList类，我们就再也不用使用循环来释放了对象。这就避免了释放链... 阅读全文
