GraphicsPath.CloseAllFigures 方法

定义

命名空间:

System.Drawing.Drawing2D

程序集:

System.Drawing.Common.dll

包:

System.Drawing.Common v8.0.0

Source:

GraphicsPath.cs

闭合此路径中所有开放的图形并开始一个新图形。 它通过连接一条从图形的终结点到起始点的直线，闭合每一开放的图形。

public:
 void CloseAllFigures();

public void CloseAllFigures ();

member this.CloseAllFigures : unit -> unit

Public Sub CloseAllFigures ()

示例

下面的代码示例设计用于 Windows 窗体，它需要 PaintEventArgse事件OnPaint对象。 此代码执行以下操作：

• 创建路径。

• 将几个打开的图形添加到路径。

• 关闭路径中的所有数字。

• 绘制到屏幕的路径。
