推荐答案

为此使用CollectionSource.
实例化CollectionSource作为MVVM模型的一部分，并将getCountries分配给collectionsource的source属性.
另一种方法是在xaml中为collectionsource创建资源并为其命名.这样，将使用窗口或用户控件或任何您拥有的东西自动创建集合源.然后，您可以通过其名称访问collectionsource并再次分配source属性.
另一种更简单的方法是简单地枚举getCountries并填充组合框.但这实际上不是WPF的处理方式.

Use a CollectionSource to that.
Instantiate the CollectionSource as part of a MVVM model, and assign getCountries to the source property of the collectionsource.
Another way is to create a resource in your xaml for a collectionsource and give it a name. That way the collectionsource is automatically created with the window or user control or whatever you have. You can then get to the collectionsource via its name and assign the source property again.
Another even more simple way is to simply enumerate getCountries and fill the combobox. But this is not really the WPF way of doing things.
