推荐答案
要使它成为真正的MFC，你需要进行listcontrol 可序列化的 [ ^ ]。
什么根据微软的意思是：
To make it truly MFC you would need to make your listcontrol serializable[^].
What it means according to Microsoft is:
序列化是写入或读取对象的过程持久存储介质，例如磁盘文件。序列化非常适用于在程序执行期间或之后需要维护结构化数据（如C ++类或结构）状态的情况。使用MFC提供的序列化对象允许以标准和一致的方式进行此操作，从而使用户无需手动执行文件操作。
Serialization is the process of writing or reading an object to or from a persistent storage medium such as a disk file. Serialization is ideal for situations where it is desired to maintain the state of structured data (such as C++ classes or structures) during or after execution of a program. Using the serialization objects provided by MFC allows this to occur in a standard and consistent manner, relieving the user from the need to perform file operations by hand.
使对象可序列化是一个非常简单的过程（参见上面的链接）。但是，您必须定义<<和>>操作员来往往读取CArchive。在这里，您必须定义文档结构。
首先想到的是使用以逗号分隔的文件 CSV [ ^ ]。通过这种方式，您还可以让用户通过Excel打开和查看文件。
但是，如果您的listcontrol中的值包含逗号或换行符时，必须引用这些值。请参见此处 [ ^ ]了解更多详情
Making the object serializable is a very simple process (see the link above). However, you would have to define << and >> operators to read to/fro CArchive. Here, where you will have to define the document structure.
First thing that comes to mind is to use a comma-separated file CSV[^]. By doing it this way you also provide an ability to the users to open and view the files via Excel.
However, if you have values in your listcontrol with commas or line breaks, the values would have to be quoted. See here[^] for more details
