在动画里面改变Graphic所使用SimpleMarkerSymbol的颜色

Storyboard sd = new Storyboard();

sd.AutoReverse = true;

ColorAnimation c = new ColorAnimation();

c.From = Color.FromArgb(255, 255, 0, 0);

c.To = Color.FromArgb(255, 255, 255, 255);

c.Duration = new Duration(new TimeSpan(0, 0, 0, 1, 500));

c.RepeatBehavior = RepeatBehavior.Forever;                

Storyboard.SetTarget(c, m_markerSymbol);

Storyboard.SetTargetProperty(c,  new PropertyPath("XXXX.XXX"));

sd.Children.Add(c);

sd.Begin();  



其中：

m_markerSymbol = this.Resources["DefaultMarkerSymbol"] as SimpleMarkerSymbol;



<esri:SimpleMarkerSymbol x:Key="DefaultMarkerSymbol" Color="Blue" Size="20" Style="Circle"/>
