推荐答案

您不能直接在 XAML 中执行此操作(尽管您可以在代码中执行此操作，其方式与在 Windows 窗体中完全相同).您可以做的是使用数据绑定和 ItemsControl 为您创建按钮.您没有说明需要控件数组的用途，但假设您希望集合中的每个 Person 都有一个按钮:

You can't do it directly in XAML (though you can do it in code, in exactly the same way as in Windows Forms). What you can do instead is use data binding and ItemsControl to create the buttons for you. You don't say what you need the control array for, but suppose you want a button for each Person in a collection:

// Code behind
public Window1()
{
  var people = new ObservableCollection<Person>();
  // Populate people
  DataContext = people;
}

// XAML
<ItemsControl ItemsSource="{Binding}" BorderThickness="0">
  <ItemsControl.ItemTemplate>
    <DataTemplate>
      <Button Content="{Binding Name}"
              Click="PersonButton_Click"
              Margin="4"
              />
    </DataTemplate>
  </ItemsControl.ItemTemplate>
</ItemsControl>

您实际上可以使用 ObjectDataProvider 和 CollectionViewSource 在 XAML 中设置整个内容，但这应该足以让您入门.显然，源可以是业务数据以外的其他内容，具体取决于您需要数组"的用途.

You can actually set up the whole thing in XAML using the ObjectDataProvider and CollectionViewSource, but this should be enough to get you started. And obviously the source can be something other than business data depending on what you need the "array" for.
