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 v9.0.0-preview.5.24306.5

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

布爾值，指定新增路徑中的第一個圖是否為這個路徑中最後一個圖的一部分。 true 的值指定新增路徑中的第一個圖表是這個路徑中最後一個圖的一部分。 false 值指定新增路徑中的第一個圖與這個路徑的最後一個圖分開。

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。 程式代碼會執行下列動作：

• 建立兩個路徑，一個是右上三角形，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。
