Intersect(GraphicsPath)

來源:

將此 Region 更新為本身與指定之 GraphicsPath交集。

public:
 void Intersect(System::Drawing::Drawing2D::GraphicsPath ^ path);

public void Intersect (System.Drawing.Drawing2D.GraphicsPath path);

member this.Intersect : System.Drawing.Drawing2D.GraphicsPath -> unit

Public Sub Intersect (path As GraphicsPath)

參數

path

GraphicsPath

要與這個 Region交集的 GraphicsPath。

範例

如需程式代碼範例，請參閱 RectangleF.Intersect(RectangleF) 和 Complement(GraphicsPath) 方法。

Intersect(Rectangle)

來源:

Region.cs

將此 Region 更新為本身與指定之 Rectangle 結構的交集。

public:
 void Intersect(System::Drawing::Rectangle rect);

public void Intersect (System.Drawing.Rectangle rect);

member this.Intersect : System.Drawing.Rectangle -> unit

Public Sub Intersect (rect As Rectangle)

參數

rect

Rectangle

要與這個 Region相交的 Rectangle 結構。

範例

如需程式代碼範例，請參閱 Intersect(RectangleF) 方法。

Intersect(RectangleF)

來源:

Region.cs

將此 Region 更新為本身與指定之 RectangleF 結構的交集。

public:
 void Intersect(System::Drawing::RectangleF rect);

public void Intersect (System.Drawing.RectangleF rect);

member this.Intersect : System.Drawing.RectangleF -> unit

Public Sub Intersect (rect As RectangleF)

參數

rect

RectangleF

要與這個 Region相交的 RectangleF 結構。

範例

下列程式代碼範例是專為搭配 Windows Forms 使用而設計，而且需要 PaintEventArgse，這是 Paint 事件處理程式的參數。 程式代碼會執行下列動作：

• 建立第一個矩形，並將它繪製到黑色的畫面。

• 建立第二個矩形，並以紅色將它繪製到畫面。

• 從第一個矩形建立區域。

• 當與第二個矩形結合時，取得區域的交集區域。

• 以藍色填滿交集的區域，並將其繪製到螢幕。

請注意，只有區域和矩形的重疊區域是藍色。
