GraphicsPath.CloseFigure 方法

定义

命名空间:

System.Drawing.Drawing2D

程序集:

System.Drawing.Common.dll

包:

System.Drawing.Common v9.0.0-preview.6.24327.6

Source:

GraphicsPath.cs

关闭当前图并启动新图。 如果当前图包含连接线和曲线序列，则该方法通过将一条线从终结点连接到起点来关闭循环。

public:
 void CloseFigure();

public void CloseFigure ();

member this.CloseFigure : unit -> unit

Public Sub CloseFigure ()

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。 该代码通过创建新路径、启动图、向图形添加两条相交线，然后关闭该图以形成三角形，从而创建三角形。 然后，路径将绘制到屏幕。

private:
   void CloseFigureExample( PaintEventArgs^ e )
   {
      // Create a path consisting of two, open-ended lines and close
      // the lines using CloseFigure.
      GraphicsPath^ myPath = gcnew GraphicsPath;
      myPath->StartFigure();
      myPath->AddLine( Point(10,10), Point(200,10) );
      myPath->AddLine( Point(200,10), Point(200,200) );
      myPath->CloseFigure();

      // Draw the path to the screen.
      e->Graphics->DrawPath( Pens::Black, myPath );
   }

private void CloseFigureExample(PaintEventArgs e)
{
             
    // Create a path consisting of two, open-ended lines and close
             
    // the lines using CloseFigure.
    GraphicsPath myPath = new GraphicsPath();
    myPath.StartFigure();
    myPath.AddLine(new Point(10, 10), new Point(200, 10));
    myPath.AddLine(new Point(200, 10), new Point(200, 200));
    myPath.CloseFigure();
             
    // Draw the path to the screen.
    e.Graphics.DrawPath(Pens.Black, myPath);
}

Public Sub CloseFigureExample(ByVal e As PaintEventArgs)

    ' Create a path consisting of two, open-ended lines and close

    ' the lines using CloseFigure.
    Dim myPath As New GraphicsPath
    myPath.StartFigure()
    myPath.AddLine(New Point(10, 10), New Point(200, 10))
    myPath.AddLine(New Point(200, 10), New Point(200, 200))
    myPath.CloseFigure()

    ' Draw the path to the screen.
    e.Graphics.DrawPath(Pens.Black, myPath)
End Sub
