WPF使用Path在C#后台使用代码画线,动态添加至canvas

本文主要是介绍WPF使用Path在C#后台使用代码画线,动态添加至canvas，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

PathFigure myPathFigure = new PathFigure();//画第一条直线
myPathFigure.StartPoint = new Point(0, 0);
LineSegment myLineSegment = new LineSegment();
myLineSegment.Point = new Point(50, 50);
PathSegmentCollection myPathSegmentCollection = new PathSegmentCollection();
myPathSegmentCollection.Add(myLineSegment);
myPathFigure.Segments = myPathSegmentCollection;

PathFigure myPathFigure2 = new PathFigure();//画第二条直线
myPathFigure2.StartPoint = new Point(0, 0);
LineSegment myLineSegment2 = new LineSegment();
myLineSegment2.Point = new Point(50, 100);
PathSegmentCollection myPathSegmentCollection2 = new PathSegmentCollection();
myPathSegmentCollection2.Add(myLineSegment2);
myPathFigure2.Segments = myPathSegmentCollection2;

PathFigureCollection myPathFigureCollection = new PathFigureCollection();
myPathFigureCollection.Add(myPathFigure);//添加画的线段
myPathFigureCollection.Add(myPathFigure2);

PathGeometry myPathGeometry = new PathGeometry();
myPathGeometry.Figures = myPathFigureCollection;

Path myPath = new Path();
myPath.Stroke = Brushes.Green;//设置Path基础属性
myPath.StrokeThickness = 3;
myPath.Data = myPathGeometry;
canvas.Children.Add(myPath);
