AddLine(Int32, Int32, Int32, Int32)
- Source:
- GraphicsPath.cs
- Source:
- GraphicsPath.cs
Appends a line segment to the current figure.
public:
void AddLine(int x1, int y1, int x2, int y2);
public void AddLine (int x1, int y1, int x2, int y2);
member this.AddLine : int * int * int * int -> unit
Public Sub AddLine (x1 As Integer, y1 As Integer, x2 As Integer, y2 As Integer)
Parameters
- x1

The x-coordinate of the starting point of the line.
- y1
- Int32
The y-coordinate of the starting point of the line.
- x2
- Int32
The x-coordinate of the endpoint of the line.
- y2
- Int32

Examples
The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e
, 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 symmetrical 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 symmetrical 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.
