本文实例为大家分享了WPF实现画线动画的具体代码，供大家参考，具体内容如下
需求：一条直线（不是曲线），模范笔画一样在画布上逐渐画出来。但前提是，用后台代码实现，并非WPF标签
效果：
上代码：
/// <summary> /// Window2.xaml 的交互逻辑 /// </summary> public partial class Window2 : Window {
public Window2() {
InitializeComponent();
var canvas = new Canvas();
Content = canvas;
var points = new List<Point>() {
new Point(10, 10), new Point(90, 90), new Point(60, 10), new Point(250, 90), new Point(10, 10) }
;
var sb = new Storyboard();
for (int i = 0;
i < points.Count - 1;
i++) {
var lineGeometry = new LineGeometry(points[i], points[i]);
var path = new Path() {
Stroke = Brushes.Black, StrokeThickness = 2, Data = lineGeometry }
;
canvas.Children.Add(path);
var animation = new PointAnimation(points[i], points[i + 1], new Duration(TimeSpan.FromMilliseconds(1000))) {
BeginTime = TimeSpan.FromMilliseconds(i * 1010) }
;
sb.Children.Add(animation);
RegisterName("geometry" + i, lineGeometry);
Storyboard.SetTargetName(animation, "geometry" + i);
Storyboard.SetTargetProperty(animation, new PropertyPath(LineGeometry.EndPointProperty));
}
MouseDown += (s, e) => sb.Begin(this);
}
}
