如何将一个列表框中的多个选定项目添加/移动到另一个列表框？

Question

我有一个小原型，允许从一个列表框添加选定的项目到另一个。我需要能够从列表框中选择多个项目并将它们移动到另一个项目并向后移动 - 从第二个列表框到第一个列表框。我想知道如果有人有好的样本或可以修改我已经有的代码。先谢谢你。

两个列表框和按钮XAML：

<Grid x:Name="LayoutRoot"> 
    <Grid.ColumnDefinitions> 
     <ColumnDefinition/> 
    </Grid.ColumnDefinitions>  
    <Border Margin="0,40,225,20"> 
     <ListBox x:Name="LeftListBox" SelectionMode="Multiple"/> 
    </Border> 
    <Border Margin="0,40,20,20" BorderThickness="1" BorderBrush="#FFCECECE" HorizontalAlignment="Right" Width="169" Padding="5" > 
     <ListBox x:Name="RightListBox" BorderThickness="0" /> 
    </Border> 
    <Button x:Name="AddButton" Height="40" Margin="0,3,198,0" VerticalAlignment="Center" Click="AddButton_Click" HorizontalAlignment="Right" Width="15" Content="▶" /> 
    <Button x:Name="RemoveButton" Height="40" Margin="0,94,198,0" VerticalAlignment="Center" Click="RemoveButton_Click" HorizontalAlignment="Right" Width="15" Content="R" /> 
</Grid> 

后面的代码：

public partial class SelectServersUC : UserControl 
{ 

    private ArrayList myDataList = null; 
    string currentItemText ; 
    int currentItemIndex ; 

    public SelectServersUC() 
    { 
     this.InitializeComponent(); 
     myDataList = LoadListBoxData(); 
     LeftListBox.ItemsSource = myDataList; 
    } 
    private void UserControl_Loaded(object sender, RoutedEventArgs e) 
    { 
     myDataList = LoadListBoxData(); 
     LeftListBox.ItemsSource = myDataList; 
    } 
    private ArrayList LoadListBoxData() 
    { 
     ArrayList itemsList = new ArrayList(); 
     itemsList.Add("Item1"); 
     itemsList.Add("Item2"); 
     itemsList.Add("Item3"); 
     itemsList.Add("Item4"); 
     itemsList.Add("Item5"); 
     itemsList.Add("Item6"); 
     itemsList.Add("Item7"); 
     itemsList.Add("Item8"); 
     itemsList.Add("Item9"); 
     itemsList.Add("Item10"); 
     return itemsList; 
    } 

    private void AddButton_Click(object sender, RoutedEventArgs e) 
    { 
     // Find the right item and it's value and index 
     currentItemText = LeftListBox.SelectedValue.ToString(); 
     currentItemIndex = LeftListBox.SelectedIndex; 

     RightListBox.Items.Add(currentItemText); 
     if (myDataList != null) 
     { 
      myDataList.RemoveAt(currentItemIndex); 
     } 

     // Refresh data binding 
     ApplyDataBinding(); 
    } 

    private void RemoveButton_Click(object sender, RoutedEventArgs e) 
    { 
     // Find the right item and it's value and index 
     currentItemText = RightListBox.SelectedValue.ToString(); 
     currentItemIndex = RightListBox.SelectedIndex; 
     // Add RightListBox item to the ArrayList 
     myDataList.Add(currentItemText); 

     // LeftListBox.Items.Add(RightListBox.SelectedItem); 
     RightListBox.Items.RemoveAt(RightListBox.Items.IndexOf(RightListBox.SelectedItem)); 

     // Refresh data binding 
     ApplyDataBinding(); 
    } 

    /// <summary> 
    /// Refreshes data binding 
    /// </summary> 
    private void ApplyDataBinding() 
    { 
     LeftListBox.ItemsSource = null; 
     // Bind ArrayList with the ListBox 
     LeftListBox.ItemsSource = myDataList; 
    }

public partial class listtolist : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 

    } 
    protected void Button1_Click(object sender, EventArgs e) 
    { 
     for (int i = ListBox1.Items.Count - 1; i >= 0; i--) 
     { 
      if (ListBox1.Items[i].Selected) 
      { 
       ListBox2.Items.Add(ListBox1.Items[i]); 
       ListBox1.Items.Remove(ListBox1.Items[i]); 
      } 
     } 
    } 
    protected void Button2_Click(object sender, EventArgs e) 
    { 
     for (int i = ListBox2.Items.Count - 1; i >= 0; i--) 
     { 
      if (ListBox2.Items[i].Selected) 
      { 
       ListBox1.Items.Add(ListBox2.Items[i]); 
       ListBox2.Items.Remove(ListBox2.Items[i]); 
      } 
     } 
    } 
}
