WP如何通过代码给ListBox的Item添加事件？
ListBox的xaml代码如下：

<ListBox Margin="0,170,0,0" Name="UnreadList" Foreground="#FF019B9B" Background="Transparent"></ListBox>

后台处理的cs代码如下：

foreach (Unread data in _unreadEntries)
            {
                UnreadList.Items.Add(
                    new TextBlock
                    {                        
                        Text=data.nickname,
                        FontSize=20,
                        Margin=new Thickness(110,-100,256,60),
                        Width=100,
                        Height=30,
                        Name = "Nickname" + data.uid,
                    }
                );
                UnreadList.Items.Add(
                    new TextBlock
                    {
                        Text = data.type,
                        FontSize = 20,
                        Margin = new Thickness(210,-100, 0, 60),
                        Width = 256,
                        Height = 30,
                        Name = "Type" + data.uid,
                    }
                );
            }

想在foreach中为对应的Item定义一个带参数的事件，该如何实现呢？

[解决办法]

UnreadList.SelectionChanged += UnreadList_SelectionChanged;
foreach (Unread data in _unreadEntries)
{
    UnreadList.Items.Add(
        new TextBlock
        {                        
            Text=data.nickname,
            FontSize=20,
            Margin=new Thickness(110,-100,256,60),
            Width=100,
            Height=30,
            Name = "Nickname" + data.uid,
            Tag=data.uid,
         }
      );
            UnreadList.Items.Add(
                new TextBlock
                {
                    Text = data.type,
                    FontSize = 20,
                    Margin = new Thickness(210,-100, 0, 60),
                    Width = 256,
                    Height = 30,
                    Name = "Type" + data.uid,
                    Tag=data.uid,
                }
            );
}

        void UnreadList_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            var obj = ((ListBox)sender).SelectedItem;
            string label=String.Empty;
            if (obj==null) return;
            if ((obj as Image) != null)
            {
                Image temp = (Image)obj;
                label = temp.Tag.ToString(); 
 
            }
            else if ((obj as TextBlock) != null)
            {
                TextBlock temp = (TextBlock)obj;
                label = temp.Tag.ToString();
            }
            else
            {
                Deployment.Current.Dispatcher.BeginInvoke(() =>
                {
                    MessageBox.Show("Error type:"+obj.GetType().ToString());
                });
            }
            Deployment.Current.Dispatcher.BeginInvoke(() =>
            {
                MessageBox.Show(label);
            });
        }
