WPF Path

在WPF中，自定义控件，经常用到Path.

Path可以绘制多边形、边框、线条、简单的图标等。

1、Xaml中用法：

<Path Stroke="DodgerBlue" StrokeThickness="1" Data="M50,50 L100,200 L200,50 L50,50"></Path>

2、后台中用法：

        Path path=new Path();
        path.Stroke = Brushes.DodgerBlue;
        path.StrokeThickness = 1;
        var aaa = new PathSegmentCollection();
        aaa.Add(new LineSegment(new Point(200,20),true));
        path.Data=new PathGeometry()
        {
            Figures = new PathFigureCollection()
            {
                new PathFigure()
                {
                    IsClosed = true,
                    StartPoint = new Point(10,10),
                    Segments = aaa
                }
            }
        };
