推荐答案

最简单的方法是使用内置数据绑定来获取用户选择。

The simplest way is to use the built in data binding to get user selections.

// Example data binding class
public class MyData
{
  public int Id { get; set; }
  public string Name { get; set; }
}

XAML用于显示数据

XAML for displaying the data

<listview x:name="lst_Data" xmlns:x="#unknown">
 <listview.view>
  <gridview>
   <gridview.columns>
    <gridviewcolumn header="ID" displaymemberbinding="{Binding Id}" />
    <gridviewcolumn header="Name" displaymemberbinding="{Binding Name}" />
   </gridview.columns>
  </gridview>
 </listview.view>
</listview>

And在这里加载和绑定数据时沿着这些方向的东西

And something along these lines when loading and binding the data here

public void LoadMyData()
{
 MyData[] _myData = FetchMyData(); // All you really need is an IEnumerable to bind data to
 lst_Data.DataContext = typeof(MyData);
 lst_Data.ItemsSource = _myData;
}

然后获取最终用户选择的数据

And then to get which data is selected by the end user

public void UserSelectedSomething(object sender, EventArgs e)
{
 if (lst_Data.SelectedItem == null)
   return;
 
 MyData selectedData = lst_Data.SelectedItem as MyData;

 if (selectedData == null)
   // Oops!  Handle
 else
   // Do something with data
}
