This example shows you how to draw lines by using the Line element.

To draw a line, create a Line element. Use its X1 and Y1 properties to set its start point; and use its X2 and Y2 properties to set its end point. Finally, set its Stroke and StrokeThickness because a line without a stroke is invisible.

Setting the Fill element for a line has no effect, because a line has no interior.

The following example draws three lines inside a Canvas element.

<Canvas Height="300" Width="300">

  <!-- Draws a diagonal line from (10,10) to (50,50). -->
  <Line
    X1="10" Y1="10"
    X2="50" Y2="50"
    Stroke="Black"
    StrokeThickness="4" />

  <!-- Draws a diagonal line from (10,10) to (50,50)
       and moves it 100 pixels to the right. -->
  <Line
    X1="10" Y1="10"
    X2="50" Y2="50"
    StrokeThickness="4"
    Canvas.Left="100">
    <Line.Stroke>
      <RadialGradientBrush GradientOrigin="0.5,0.5" Center="0.5,0.5" RadiusX="0.5" RadiusY="0.5">
        <RadialGradientBrush.GradientStops>
          <GradientStop Color="Red" Offset="0" />
          <GradientStop Color="Blue" Offset="0.25" />
        </RadialGradientBrush.GradientStops>
      </RadialGradientBrush>
    </Line.Stroke>
  </Line>

  <!-- Draws a horizontal line from (10,60) to (150,60). -->
  <Line
     X1="10" Y1="60"
     X2="150" Y2="60"
     Stroke="Black"
     StrokeThickness="4"/>

</Canvas>
