Example

[Visual Basic, C#] The following example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a black pen.
  • Creates the coordinates of the endpoints of the line.
  • Draws the line to the screen.
[Visual Basic, C#] Note   This example shows how to use one of the overloaded versions of DrawLine. For other examples that might be available, see the individual overload topics.
[Visual Basic] 
Public Sub DrawLineFloat(e As PaintEventArgs)
' Create pen.
Dim blackPen As New Pen(Color.Black, 3)
' Create coordinates of points that define line.
Dim x1 As Single = 100F
Dim y1 As Single = 100F
Dim x2 As Single = 500F
Dim y2 As Single = 100F
' Draw line to screen.
e.Graphics.DrawLine(blackPen, x1, y1, x2, y2)
End Sub
        
[C#] 
public void DrawLineFloat(PaintEventArgs e)
{
// Create pen.
Pen blackPen = new Pen(Color.Black, 3);
// Create coordinates of points that define line.
float x1 = 100.0F;
float y1 = 100.0F;
float x2 = 500.0F;
float y2 = 100.0F;
// Draw line to screen.
e.Graphics.DrawLine(blackPen, x1, y1, x2, y2);
}
