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 }
