WPF实现画线动画效果

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：

/// 
 
  /// Window2.xaml 的交互逻辑 
  /// 
 
  public partial class Window2 : Window 
  { 
    public Window2() 
    { 
      InitializeComponent(); 
      var canvas = new Canvas(); 
      Content = canvas; 
      var points = 
 new List() 
 { 
   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); 
    } 
  }
