GraphicsPath.AddPath(GraphicsPath, Boolean) 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

將指定的 GraphicsPath 附加至這個路徑。

public:
 void AddPath(System::Drawing::Drawing2D::GraphicsPath ^ addingPath, bool connect);

public void AddPath (System.Drawing.Drawing2D.GraphicsPath addingPath, bool connect);

member this.AddPath : System.Drawing.Drawing2D.GraphicsPath * bool -> unit

Public Sub AddPath (addingPath As GraphicsPath, connect As Boolean)

參數

addingPath

GraphicsPath

要加入的 GraphicsPath。

connect

Boolean

布林 (Boolean) 值，指定加入的路徑中第一個圖形是否為這個路徑中最後圖形的一部分。 true 值會指定 (如果可能) 加入的路徑中第一個圖形是這個路徑最後圖形的一部分。 false 值會指定加入的路徑中第一個圖形和這個路徑中最後一個圖形是分開的。

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：

• 建立兩個路徑，一個靠右三角形，另一個是向上三角形。

• 將第二個路徑新增至第一個路徑。

• 繪製畫面的結果路徑。
