我正在使用循环选择器来可视化标志，这些标志以经典方式加载到列表中，如图所示：

public MainPage()
{
    InitializeComponent();

    List<DataContinent> data = new List<DataContinent>(); 
    data.Add(new DataContinent() { Flag = new Uri("/Images/Albania.png", UriKind.Relative).ToString() });
    data.Add(new DataContinent() { Flag = new Uri("/Images/Andorra.png", UriKind.Relative).ToString() });
    ...
    ...
    this.loopingSelectorContinent.DataSource = new ListLoopingDataSource<DataContinent>() {Items = data, SelectedItem = data[0]};
}

是否可以在运行时根据所选大陆在循环选择器中加载不同的图像，或者作为替代方案，防止某些项目的循环？

我找到了一种解决我将要描述的问题的简单方法，因为它可能对其他人有用。基本上，与其在 Main 内部初始化循环选择器，不如在外部完成，然后在必要时调用适当的函数。这里有一个例子：

public MainPage()
{
    InitializeComponent();
    Europe(); //standard visualization
}

public void Europe()
{
    List<DataContinent> data = new List<DataContinent>(); 
    data.Add(new DataContinent() { Flag = new Uri("/Images/Albania.png", UriKind.Relative).ToString() });
    data.Add(new DataContinent() { Flag = new Uri("/Images/Andorra.png", UriKind.Relative).ToString() });
    ...
    ...
    this.loopingSelectorContinent.DataSource = new ListLoopingDataSource<DataContinent>() {Items = data, SelectedItem = data[0]};
}
public void Africa()
{
    List<DataContinent> data = new List<DataContinent>(); 
    data.Add(new DataContinent() { Flag = new Uri("/Images/Algeria.png", UriKind.Relative).ToString() });
    data.Add(new DataContinent() { Flag = new Uri("/Images/Angola.png", UriKind.Relative).ToString() });
    ...
    ...
    this.loopingSelectorContinent.DataSource = new ListLoopingDataSource<DataContinent>() {Items = data, SelectedItem = data[0]};
}

private void button1_Click(object sender, RoutedEventArgs e) //loopingselector populated with European flags
{
Europe();
}

private void button2_Click(object sender, RoutedEventArgs e) //loopingselector populated with African flags
{
Africa();
}
