推荐答案

看起来像有点像CSV列表。 CSV @ Wikipedia [ ^ ]



这简单易行。



2版本：



在应用的生命周期内将列表保存在存储中。你可以简单地在列表上工作，快速响应。

另一方面，列表需要在应用程序结束时/之前写入文件。



存储到文件。您需要将存储中的列表与文件中的列表相同。

Looks a bit like a CSV-Listing. CSV @ Wikipedia[^]

That makes it a simple thing.

2 Versions:

Keep the list in storage during lifetime of your app. You can simply work on the list, have it fast in respons.
On the other hand the list needs to be written to file when/before the app is ended.

Store to file. You will need to make soure your list in store is same as in file.
