如何以2秒的时间间隔播放图像的幻灯片。我从stackoverflow中引用了下面的代码,但是在运行iam时显示任何图像..请在哪里发生错误...
的Xaml:
<image Name=myImg Source={Binding bi}/>
代码:
private DispatcherTimer tmr = new DispatcherTimer();
private List<string> images = new List<string>();
private int imageIndex = 0;
public MainPage()
{
InitializeComponent();
Loaded += new RoutedEventHandler(MainPage_Loaded);
}
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
tmr.Interval = TimeSpan.FromSeconds(5);
tmr.Tick += new EventHandler(tmr_Tick);
LoadImages();
ShowNextImage();
}
private void LoadImages()
{
// list the files (includede in the XAP file) here
images.Add("/images/filename1.jpg");
images.Add("/images/filename2.jpg");
images.Add("/images/filename3.jpg");
images.Add("/images/filename4.jpg");
}
private void ShowNextImage()
{
Imagesource bi = new BitmapImage(new Uri(images[imageIndex], UriKind.Relative));
myImg.Source = bi;
imageIndex = (imageIndex + 1) % images.Count;
}
void tmr_Tick(object sender, EventArgs e)
{
ShowNextImage();
}
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
if (!tmr.IsEnabled)
{
tmr.Start();
}
base.OnNavigatedTo(e);
}
protected override void OnNavigatedFrom(System.Windows.Navigation.NavigationEventArgs e)
{
tmr.Stop();
base.OnNavigatedFrom(e);
}
先谢谢
答案 0 :(得分:0)
将Name=myImg
更改为x:Name="myImg"
并完全删除Source
属性。否则它看起来应该有效。
