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); }
