从ListBox中单击的项目获取数据

我是Windows Phone的新手，

我有一个带有文本块的列表框，我想从列表框中的选定项目中获取所有数据。

这是我的代码片段：

.xaml文件

.cs文件

  void listBox1_SelectionChanged(object sender, SelectionChangedEventArgs args) { Debug.WriteLine(" You selected " +listbox1.SelectedItem.ToString()); } 

我的控制台以这种方式显示输出： You selected Appname.Pagename.methodname

绑定到ListBox的类

  public class Attractions { [JsonProperty("AttractionName")] public string AttractionName { get; set; } [JsonProperty("IphoneImage")] public string IphoneImage { get; set; } [JsonProperty("price")] public string price { get; set; } } 

Answer 1

有几种方法可以做到：

 private void listBox1_SelectionChanged(object sender, SelectionChangedEventArgs args) { if (listBox1.SelectedIndex == -1) return; Attractions first = listbox1.SelectedItem as Attractions ; Attractions second = (Attractions)listBox1.Items[listBox1.SelectedIndex]; Attractions third = (sender as ListBox).SelectedItem as Attractions; Attractions fourth = args.AddedItems[0] as Attractions; Debug.WriteLine(" You selected " + first.AttractionName); } 

使用SelectedItem（索引），您将获得一个项目，即ItemsSource Collection的类型。 获得物品后，您可以随心所欲地完成任务。

Answer 2

在SelectionChange Event内部放置以下代码

 Attractions lbi = (sender as ListBox).SelectedItem as Attractions; 

您可以使用访问该类的属性

 lbi.price 

Answer 3

写下这段代码

这可以帮到你

 void listBox1_SelectionChanged(object sender, SelectionChangedEventArgs args) { Debug.WriteLine(" You selected " +listBox1.Items[listBox1.SelectedIndex].ToString ()); }
