回答by Rang
if you want to draw it with Line, write a method, or you can use Polyline
如果你想用 绘制它Line，写一个方法，或者你可以使用Polyline
public MainWindow()
{
InitializeComponent();
canvas.Children.Clear();
Point[] points = new Point[4]
{
new Point(0, 0),
new Point(300 , 300),
new Point(400, 500),
new Point(700, 100 )
};
DrawLine(points);
//DrawLine2(points);
}
private void DrawLine(Point[] points)
{
int i;
int count = points.Length;
for (i = 0; i < count - 1; i++)
{
Line myline = new Line();
myline.Stroke = Brushes.Red;
myline.X1 = points[i].X;
myline.Y1 = points[i].Y;
myline.X2 = points[i + 1].X;
myline.Y2 = points[i + 1].Y;
canvas.Children.Add(myline);
}
}
private void DrawLine2(Point[] points)
{
Polyline line = new Polyline();
PointCollection collection = new PointCollection();
foreach(Point p in points)
{
collection.Add(p);
}
line.Points = collection;
line.Stroke = new SolidColorBrush(Colors.Black);
line.StrokeThickness = 1;
canvas.Children.Add(line);
}
