我不知道我是否接近這個錯誤或者我的代碼中是否有錯誤。
正如我上面所說，我想通過 C# 代碼而不是 XAML 來解決問題。
我沒有收到任何編譯器錯誤，它什么也不做。
XAML：
<Button Content="Rotate" HorizontalAlignment="Left" Margin="1007,637,0,0" VerticalAlignment="Top" Click="Button_Click" Height="36" Width="51"/>
<Image x:Name="Brett" Margin="0,-563,0,187" Stretch="Fill" Source="/Monopoly_Brett_bib.png" RenderTransformOrigin="0.5, 0.5" OpacityMask="White"></Image>
C＃：
private void Button_Click(object sender, RoutedEventArgs e)
{
DoubleAnimation doubleAnimation = new DoubleAnimation();
doubleAnimation.Duration = new Duration(new TimeSpan(0, 0, 0, 3, 0));
Storyboard storyBoard = new Storyboard();
storyBoard.Children.Add(doubleAnimation);
Storyboard.SetTarget(doubleAnimation, Brett);
Storyboard.SetTargetProperty(doubleAnimation, new PropertyPath(RotateTransform.AngleProperty));
doubleAnimation.From = 0;
doubleAnimation.To = -90;
storyBoard.Begin();
storyBoard.Completed = StoryBoard_Completed;
}
uj5u.com熱心網友回復：
嘗試這個：
private void Button_Click(object sender, RoutedEventArgs e)
{
DoubleAnimation doubleAnimation = new DoubleAnimation
{
From =0,
To = -90,
Duration = new Duration(TimeSpan.FromSeconds(3))
};
Storyboard storyBoard = new Storyboard();
Brett.RenderTransform = new RotateTransform();
storyBoard.Children.Add(doubleAnimation);
Storyboard.SetTarget(doubleAnimation, Brett);
Storyboard.SetTargetProperty(doubleAnimation, new PropertyPath("RenderTransform.Angle"));
storyBoard.Begin();
}
