WPF C#如何在两个集合之间进行选择以基于活动按钮在GridView中使用

private ObservableCollection<Item> allItems;
private ObservableCollection<Item> selectedItems;

<ListView ItemsSource="{Binding allItems}">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}" />
            <GridViewColumn Header="Description" DisplayMemberBinding="{Binding Description}" />
            <!-- 其他列 -->
        </GridView>
    </ListView.View>
</ListView>

<Button Content="Add" Command="{Binding AddCommand}" />
<Button Content="Remove" Command="{Binding RemoveCommand}" />

public ICommand AddCommand { get; private set; }
public ICommand RemoveCommand { get; private set; }

public ViewModel()
{
    AddCommand = new RelayCommand(Add, CanAdd);
    RemoveCommand = new RelayCommand(Remove, CanRemove);
}

private void Add()
{
    // 将选定的项从allItems集合中移除，并添加到selectedItems集合中
    Item selectedItem = allItems.FirstOrDefault(item => item.IsSelected);
    if (selectedItem != null)
    {
        allItems.Remove(selectedItem);
        selectedItems.Add(selectedItem);
    }
}

private bool CanAdd()
{
    // 检查是否有选定的项可供添加
    return allItems.Any(item => item.IsSelected);
}

private void Remove()
{
    // 将选定的项从selectedItems集合中移除，并添加到allItems集合中
    Item selectedItem = selectedItems.FirstOrDefault(item => item.IsSelected);
    if (selectedItem != null)
    {
        selectedItems.Remove(selectedItem);
        allItems.Add(selectedItem);
    }
}

private bool CanRemove()
{
    // 检查是否有选定的项可供移除
    return selectedItems.Any(item => item.IsSelected);
}

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        DataContext = new ViewModel();
    }
}
