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：

/// <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); 
    } 
  }
