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

範例
以下程式碼範例是為 Windows Forms 設計的,並需要 PaintEventArgse,這是 Paint 事件處理程序的參數。 此程式碼會執行下列動作:
建立第一個矩形,並以黑色繪製到螢幕上。
建立第二個矩形,並以紅色畫到螢幕上。
從第一個矩形建立一個區域。
與第二個矩形結合後,得到該區域的交集面積。
用藍色填滿交叉點區域並畫到螢幕上。
注意只有區域和矩形重疊的區域是藍色的。

void Intersect_RectF_Example( PaintEventArgs^ e )

Rectangle regionRect = Rectangle(20,20,100,100);

// create the second rectangle and draw it to the screen in red.
RectangleF complementRect = RectangleF(90,30,100,100);
e->Graphics->DrawRectangle( Pens::Red, Rectangle::Round( complementRect ) );
// Create a region using the first rectangle.
System::Drawing::Region^ myRegion = gcnew System::Drawing::Region( regionRect );
// Get the area of intersection for myRegion when combined with
// complementRect.
myRegion->Intersect( complementRect );
// Fill the intersection area of myRegion with blue.
