ApplicationSettingsBase 没有按预期序列化我的 类
ApplicationSettingsBase is not serializing my classes as expected
我正在尝试使用 ApplicationSettingsBase 来保存我的 classes。我这里有一个例子。我也尝试过不使用 ApplicationSettingsBase 并且似乎工作正常。该示例在下面。
有人可以指导我使用 ApplicationSettingsBase 来保存完整的 class 层次结构吗？谢谢，谢谢。
我在第一个示例中保存了一些中间实例以尝试解决这个问题。我不打算在最终实施中这样做。我可以在这里看到它会保存中间数据而不是嵌套数据。就是不明白。

几乎回答了我的问题：
In particular, Properties.Settings.Default would normally return an
instance of a Designer-created class named Settings. Calling
Properties.Settings.Default.Save(); will save only the values in that
object, not those in some other class.
If you have a separate class DeviceConfiguration that you want saved
(as you seem to in the code you posted), you need to handle that
explicitly. Simply having an instance of a subclass of
ApplicationSettingsBase won't do it. You need to call the Save()
method on that custom subclass yourself.
我没有意识到我的自定义结构不必放在 Properties.Settings 中就可以保存到 user.config 文件中。
我正在尝试使用 ApplicationSettingsBase 来保存我的 classes。我这里有一个例子。我也尝试过不使用 ApplicationSettingsBase 并且似乎工作正常。该示例在下面。
有人可以指导我使用 ApplicationSettingsBase 来保存完整的 class 层次结构吗？谢谢，谢谢。
我在第一个示例中保存了一些中间实例以尝试解决这个问题。我不打算在最终实施中这样做。我可以在这里看到它会保存中间数据而不是嵌套数据。就是不明白。
