How to: Draw a Line
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.
Example
<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>
