当使用多个表时，如何从XAML ListView获取id？

<ListView x:Name="myListView" SelectionChanged="ListView_SelectionChanged">
    <ListView.ItemTemplate>
        <DataTemplate>
            <StackPanel>
                <TextBlock Text="{Binding Name}" />
                <TextBlock Text="{Binding Description}" />
            </StackPanel>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

private void ListView_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (myListView.SelectedItem != null)
    {
        // 获取选中项的数据模型对象
        var selectedItem = myListView.SelectedItem as YourDataModel;

        // 获取id字段的值
        var id = selectedItem.Id;

        // 在这里处理id的值
    }
}
