generating animated line

Question

(x,y) =(10,20),(50,30),(20,20),(40,22),(45,20),(50,35),.........

I want to create an animation with .Net.Normally I am using windows form. But if needed, i can use W

Answer 1

Here's a variation on Nico's great answer. I use PointAnimation to animate the EndPoint of a LineGeometry which serves as the Data for a Path.

using System;
using System.Collections.Generic;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace SoGeneratingAnimatedLine
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            var canvas = new Canvas();

            Content = canvas;

            var points =
                new List()
                {
                    new Point(10, 10),
                    new Point(90, 10),
                    new Point(90, 90),
                    new Point(10, 90),
                    new Point(10, 10)
                };

            var sb = new Storyboard();

            for (int i = 0; i < points.Count - 1; i++)
            {
                var lineGeometry = new LineGeometry(points[i], points[i]);

                var path =
                    new Path()
                    {
                        Stroke = Brushes.Black,
                        StrokeThickness = 2,
                        Data = lineGeometry
                    };

                canvas.Children.Add(path);

                var animation =
                    new PointAnimation(points[i], points[i + 1], new Duration(TimeSpan.FromMilliseconds(1000)))
                    {
                        BeginTime = TimeSpan.FromMilliseconds(i * 1010)
                    };

                sb.Children.Add(animation);

                RegisterName("geometry" + i, lineGeometry);
                Storyboard.SetTargetName(animation, "geometry" + i);
                Storyboard.SetTargetProperty(animation, new PropertyPath(LineGeometry.EndPointProperty));                
            }

            MouseDown += (s, e) => sb.Begin(this);
        }
    }
}
