ApplicationSettingsBase没有按预期序列化我的类
ApplicationSettingsBase没有按预期序列化我的类
提问于 2015-12-23 19:58:41
我试图使用ApplicationSettingsBase来持久化我的类。我这里有个例子。我也尝试过不使用ApplicationSettingsBase，这似乎很好。下面是这个例子。
有人能给我一些关于如何使用ApplicationSettingsBase来持久化我的整个类层次结构的指导吗？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。我不打算在最后的实现中这样做。我在这里可以看到，它将保存中间数据，但不保存嵌套数据。我只是不明白。

Properties.Settings.Default.prefs = new Prefs();
Test test = new Test();
test.steps.Add("Step1");
test.steps.Add("Step2");
Properties.Settings.Default.prefs.tests.Add(test);
test.Save();
Properties.Settings.Default.Save();
Properties.Settings.Default.prefs.Save();
Environment.Exit(0);

This answer很好地回答了我的问题：
特别是，
Properties.Settings.Default通常会返回一个名为Settings的设计器创建的类的实例。调用Properties.Settings.Default.Save();只会保存该对象中的值，而不会保存其他类中的值。 如果您有一个单独的类DeviceConfiguration，您需要保存它(就像在您发布的代码中显示的那样)，您需要显式地处理它。仅仅拥有一个ApplicationSettingsBase子类的实例是做不到的。您需要自己调用自定义子类上的Save()方法。
我没有意识到我的自定义结构不需要放在Properties.Settings中才能保存到user.config文件中。
