Tak už som na to prišiel.

Do XAML pridame canvas1

Window x:Class="WpfApplication3.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Canvas Height="214" HorizontalAlignment="Left" Margin="12,12,0,0" Name="canvas1" VerticalAlignment="Top" Width="479" >
            <Line
    X1="100" Y1="50"
    X2="300" Y2="50"
    Stroke="Black"
    StrokeThickness="1" />
        </Canvas>
        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="358,266,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
    </Grid>
   
</Window>

a XAML.cs môže vyzerať trebárs takto

    {
        public MainWindow()
        {
            InitializeComponent();
        }
        
        private void button1_Click(object sender, RoutedEventArgs e)
        {
            for (int i = 0; i < 6; i++)
            {
                Shape ciara = null;
                ciara = new Line() { X1 = 100, Y1 = 50 + 10 * i, X2 = 300, Y2 = 50 + 10 * i };

                ciara.Stroke = SystemColors.WindowTextBrush;
                canvas1.Children.Add(ciara);
                
            }          
         
        }
    }
}
