GraphicsPath.CloseFigure 方法

定義

命名空間:

System.Drawing.Drawing2D

組件:

System.Drawing.Common.dll

套件:

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

來源:

GraphicsPath.cs

關閉目前的圖形，並啟動新的圖形。 如果目前的圖表包含一連串連接線和曲線，則方法會藉由從端點連接到起點的線條來關閉迴圈。

public:
 void CloseFigure();

public void CloseFigure ();

member this.CloseFigure : unit -> unit

Public Sub CloseFigure ()

範例

下列程式代碼範例的設計目的是要與 Windows Forms 搭配使用，而且需要 PaintEventArgseOnPaint 事件物件。 程序代碼會建立三角形，方法是建立新的路徑、從圖形開始、將兩條交集線新增至圖形，然後關閉圖形以形成三角形。 然後，路徑會繪製到畫面。

private:
   void CloseFigureExample( PaintEventArgs^ e )

      // the lines using CloseFigure.
