示例

下面的代码示例旨在与 Windows 窗体一起使用,它需要 PaintEventArgseOnPaint 事件对象。 该代码将创建一个路径,添加构成三角形的三行,然后将路径绘制到屏幕。

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

注解

此方法将指定点定义的线段添加到当前图的末尾。 如果 GraphicsPath中存在以前的线条或曲线,则绘制线条线段以将路径中的最后一个点连接到新线段中的第一个点。
