如何将ItemsControl中的ComboBox与Caliburn.Micro绑定？

private BindableCollection<string> _items;
public BindableCollection<string> Items
{
    get { return _items; }
    set
    {
        _items = value;
        NotifyOfPropertyChange(() => Items);
    }
}

<ItemsControl ItemsSource="{Binding Items}">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <ComboBox SelectedItem="{Binding SelectedItem, Mode=TwoWay}">
                <!-- ComboBox的其他设置 -->
            </ComboBox>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

private string _selectedItem;
public string SelectedItem
{
    get { return _selectedItem; }
    set
    {
        _selectedItem = value;
        NotifyOfPropertyChange(() => SelectedItem);
    }
}

public YourViewModel()
{
    Items = new BindableCollection<string>();
    Items.Add("Option 1");
    Items.Add("Option 2");
    // 添加其他选项
}
