Examples

The following code 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 an array of points of segments of the line.

• Draws the connected line segments to the screen.

public:
   void DrawLinesPoint( PaintEventArgs^ e )
   {
      // Create pen.
      Pen^ pen = gcnew Pen( Color::Black,3.0f );

      // Create array of points that define lines to draw.
      array<Point>^ points = {Point(10,10),Point(10,100),Point(200,50),Point(250,300)};

      //Draw lines to screen.
      e->Graphics->DrawLines( pen, points );
   }

public void DrawLinesPoint(PaintEventArgs e)
{
             
    // Create pen.
    Pen pen = new Pen(Color.Black, 3);
             
    // Create array of points that define lines to draw.
    Point[] points =
             {
                 new Point(10,  10),
                 new Point(10, 100),
                 new Point(200,  50),
                 new Point(250, 300)
             };
             
    //Draw lines to screen.
    e.Graphics.DrawLines(pen, points);
}

Public Sub DrawLinesPoint(ByVal e As PaintEventArgs)

    ' Create pen.
    Dim blackPen As New Pen(Color.Black, 3)

    ' Create array of points that define lines to draw.
    Dim points As Point() = {New Point(10, 10), New Point(10, 100), _
    New Point(200, 50), New Point(250, 300)}

    'Draw lines to screen.
    e.Graphics.DrawLines(blackPen, points)
End Sub

Remarks

This method draws a series of lines connecting an array of ending points. The first two points in the array specify the first line. Each additional point specifies the end of a line segment whose starting point is the ending point of the previous line segment.
