パラメーター

戻り値

3 番目の RectangleF 構造体のサイズは、指定した 2 つの四角形の重複領域を表します。

例

この例は Windows フォームで使用するように設計されており、OnPaint イベント オブジェクトである PaintEventArgseが必要です。 このコードでは、2 つの RectangleF オブジェクトを作成し、黒と赤で画面に描画します。 描画目的で Rectangle オブジェクトに変換する必要があることに注意してください。 次に、Intersect メソッドを使用して 3 つ目の RectangleF を作成し、Rectangleに変換して、青で画面に描画します。 3 番目の (青い) 四角形は、他の 2 つの四角形の重なりの領域であることに注意してください。

      // screen.
