WinRT信息:無法在UWP中解析TargetProperty

[英]WinRT information: Cannot resolve TargetProperty in UWP

我是Storyboard動畫的新手,

Storyboard storyBoard = new Storyboard();
foreach (var segment in this.PieSegmentCollection) 
{
    DoubleAnimation angleAnimation = new DoubleAnimation() { From = StartAngle, To = EndAngle, Duration = new Duration(TimeSpan.FromSeconds(.8)) };
    storyBoard.Children.Add(angleAnimation);
    Storyboard.SetTargetProperty(angleAnimation, "PieSegment.EndAngleProperty");
    Storyboard.SetTarget(angleAnimation, segment);
}
storyboard.Begin();

我嘗試為PieSegmentCollection中的每個片段設置動畫,但出現此錯誤

WinRT信息:無法解析指定對象上的TargetProperty(PieSegment.ArcEndAngleProperty)。

誰能幫我解決這個問題?

屬性名稱肯定是EndAngle ,因此您應該這樣設置target屬性:

Storyboard.SetTargetProperty(angleAnimation, "EndAngle");
