silverlight-4.0 - 从 Silverlight 中的代码后面定义路径数据

Question

我有以下 xaml 中的路径数据。我想从后面的代码中定义相同的路径数据。

<Path  Data="M 250,40 L200,20 L200,60 Z" />

Answer 1

从代码隐藏:

Path orangePath = new Path();

        PathFigure pathFigure = new PathFigure();

        pathFigure.StartPoint = new Point(250, 40);

        LineSegment lineSegment1 = new LineSegment();
        lineSegment1.Point = new Point(200, 20);
        pathFigure.Segments.Add(lineSegment1);

        LineSegment lineSegment2 = new LineSegment();
        lineSegment2.Point = new Point(200, 60);
        pathFigure.Segments.Add(lineSegment2);

        PathGeometry pathGeometry = new PathGeometry();
        pathGeometry.Figures = new PathFigureCollection();

        pathGeometry.Figures.Add(pathFigure);

        orangePath.Data = pathGeometry;

编辑:

//我们应该设置这个true来绘制从lineSegment2到起点的线

pathFigure.IsClosed = true;
