GraphicsPath.CloseAllFigures 方法

定義

命名空間:

System.Drawing.Drawing2D

組件:

System.Drawing.Common.dll

套件:

System.Drawing.Common v8.0.0

來源:

GraphicsPath.cs

關閉在這個路徑中的所有開放的圖形，並開始新的圖形。 它會藉由連接從其開始點至其結束點的直線來關閉每個開放的圖形。

public:
 void CloseAllFigures();

public void CloseAllFigures ();

member this.CloseAllFigures : unit -> unit

Public Sub CloseAllFigures ()

範例

下列程式代碼範例是設計來搭配 Windows Forms 使用，而且需要 PaintEventArgse事件OnPaint物件。 此程式碼會執行下列動作：

• 建立路徑。

• 將數個開啟的圖形新增至路徑。

• 關閉路徑中的所有圖表。

• 繪製畫面的路徑。
