从silverlight中的代码定义路径数据

Question

我在xaml中有以下路径数据.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

来自Codebehind:

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:

//我们必须将此设置为true以将lineSegment2中的行绘制到起始点

pathFigure.IsClosed = true;

Answer 2

你需要使用TypeConverter:

Path path = new Path();
string sData = "M 250,40 L200,20 L200,60 Z";
var converter = TypeDescriptor.GetConverter(typeof(Geometry));
path.Data = (Geometry)converter.ConvertFrom(sData);
