如何使用WPF中的动态URL绑定到图像？

public string ImageUrl
{
    get { return (string)GetValue(ImageUrlProperty); }
    set { SetValue(ImageUrlProperty, value); }
}

public static readonly DependencyProperty ImageUrlProperty =
    DependencyProperty.Register("ImageUrl", typeof(string), typeof(MainWindow), new PropertyMetadata(string.Empty, OnImageUrlChanged));

private static void OnImageUrlChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
    var mainWindow = d as MainWindow;
    mainWindow.UpdateImage();
}

private void UpdateImage()
{
    if (!string.IsNullOrEmpty(ImageUrl))
    {
        var uri = new Uri(ImageUrl, UriKind.Absolute);
        var bitmap = new BitmapImage(uri);
        myImage.Source = bitmap;
    }
    else
    {
        myImage.Source = null;
    }
}

ImageUrl = "https://example.com/image.jpg";
