如何在幻灯片放映的按钮中动态添加图像？

Question

我有一个场景，我必须制作一个幻灯片放映按钮，我已经尝试了很多但无法制作幻灯片。

Image img = new Image();
            string path = System.AppDomain.CurrentDomain.BaseDirectory + "chart2 - Copy.png";
            img.Source = new BitmapImage(new Uri(path));

            StackPanel stackPnl = new StackPanel();
            stackPnl.Orientation = Orientation.Horizontal;
            stackPnl.Margin = new Thickness(10);
            stackPnl.Children.Add(img);

            button1.Content = stackPnl;

尝试在MVVM中轻松实现。 我正在给出一个想法或模拟如何执行它。

XAML

  <Button Height="200" Width="200">
        <ControlTemplate>
            <Image>
               <Image.Source>
                   <BitmapImage UriSource="{Binding ImageURI}" />
               </Image.Source>
            </image>
        </ControlTemplate>
    </Button>

VM

private string _ImageURI = "";// add the path of your image in the quotes
        public string ImageURI { get { return _ImageURI; } set { _ImageURI = value; NotifyPropertyChanged(); } }

    public void SlideShow()
    {
        DispatcherTimer DT = new DispatcherTimer();
        DT.Tick += DT_Tick;
        DT.Interval = new TimeSpan(0, 0, 1);
        DT.Start();
    }

    private void DT_Tick(object sender, EventArgs e)
    {
        // Change your image uri here 'ImageURI'
    }

在SlideShow()或您想要的任何地方拨打VM constructor。
