public:
 void AddLine(System::Drawing::Point pt1, System::Drawing::Point pt2);

member this.AddLine : System.Drawing.Point * System.Drawing.Point -> unit
Public Sub AddLine (pt1 As Point, pt2 As Point)

Parameters

pt1
Point Point Point Point

A Point that represents the starting point of the line.

pt2

A Point that represents the endpoint of the line.

Examples

For an example, see AddLine(Int32, Int32, Int32, Int32).

Remarks

This method adds the line segment defined by the specified points to the end of this GraphicsPath. If there are previous lines or curves in the GraphicsPath, a line segment is drawn to connect the last point in the path to the first point in the new line segment.

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, an OnPaint event object. The code creates a path, adds three lines that form a triangle, and then draws the path to the screen.

private:
   void AddLineExample( PaintEventArgs^ e )
   {
      //Create a path and add a symetrical triangle using AddLine.
      GraphicsPath^ myPath = gcnew GraphicsPath;
      myPath->AddLine( 30, 30, 60, 60 );
      myPath->AddLine( 60, 60, 0, 60 );
      myPath->AddLine( 0, 60, 30, 30 );

      // Draw the path to the screen.
      Pen^ myPen = gcnew Pen( Color::Black,2.0f );
      e->Graphics->DrawPath( myPen, myPath );
   }
private void AddLineExample(PaintEventArgs e)
{
             
    //Create a path and add a symetrical triangle using AddLine.
    GraphicsPath myPath = new GraphicsPath();
    myPath.AddLine(30, 30, 60, 60);
    myPath.AddLine(60, 60, 0, 60);
    myPath.AddLine(0, 60, 30, 30);
             
    // Draw the path to the screen.
    Pen myPen = new Pen(Color.Black, 2);
    e.Graphics.DrawPath(myPen, myPath);
}
Public Sub AddLineExample(ByVal e As PaintEventArgs)

    ' Create a path and add a symetrical triangle using AddLine.
    Dim myPath As New GraphicsPath
    myPath.AddLine(30, 30, 60, 60)
    myPath.AddLine(60, 60, 0, 60)
    myPath.AddLine(0, 60, 30, 30)

    ' Draw the path to the screen.
    Dim myPen As New Pen(Color.Black, 2)
    e.Graphics.DrawPath(myPen, myPath)
End Sub

Remarks

This method adds the line segment defined by the specified points to the end of the current figure. If there are previous lines or curves in the GraphicsPath, a line segment is drawn to connect the last point in the path to the first point in the new line segment.
