效果图

可以自己绘制成圆形等任意形状到Canvas

核心代码部分

绘制部分

//Value：当前进度值 _streamGeometry=GetSinGeometry(this.Width, -5,1/30.0,-this.Width+ this.Width * Value /100, this.Height - this.Height * Value /100);GeometryGroup group=new GeometryGroup();group.Children.Add(_streamGeometry);Path myPath=new Path{Fill=Brushes.DarkGreen, Data=group};//绘制 this.Canvas.Children.Add(myPath);

正弦曲线计算波纹
