我需要释放这些物品吗？

问题描述

我正在使用Delphi 1 16位学习Pascal（不要笑，它工作正常，加上我买不起更新版本）。我使用TList来容纳一个简单的通讯录的对象引用。每个对象都被添加到TList中：

  DataList.Add（TAddrBookData.Create（'Bob'，'1 Mill St '））; 
  

我需要自己释放TAddrBookData对象吗？或者当TList.Free运行时，它们是否释放？

解决方案

您需要自己释放它们。后来的版本带有一个TObjectList，它就像一个TList，除了它只接受对象，它可以选择拥有所有权，并在释放列表时自动释放它们。但是我不相信Delphi 1中存在TObjectList，所以你必须手动处理。

I'm using Delphi 1 16-bit to learn Pascal (don't laugh, it works fine, plus I can't afford a more recent version). I'm using a TList to hold object references for a simple address book. Each object is added to the TList like so:

DataList.Add(TAddrBookData.Create('Bob', '1 Mill St'));

Do I need to free the TAddrBookData objects myself? Or are they freed when TList.Free is run?

解决方案

You need to free them yourself. Later versions come with a TObjectList, which is like a TList except it will only accept objects and it has the option to take ownership and free them for you automatically when the list is freed. But I don't believe TObjectList existed in Delphi 1, so you'll have to take care of it manually.
