RectangleF.Equality(RectangleF, RectangleF) 演算子

定義

2 つの RectangleF 構造体の位置およびサイズが同じかどうかをテストします。Tests whether two RectangleF structures have equal location and size.

public:
 static bool operator ==(System::Drawing::RectangleF left, System::Drawing::RectangleF right);
public static bool operator == (System.Drawing.RectangleF left, System.Drawing.RectangleF right);
static member ( = ) : System.Drawing.RectangleF * System.Drawing.RectangleF -> bool
Public Shared Operator == (left As RectangleF, right As RectangleF) As Boolean

パラメーター

left
RectangleF

等値演算子の左側に表示される RectangleF 構造体。The RectangleF structure that is to the left of the equality operator.

right
RectangleF

等値演算子の右側に表示される RectangleF 構造体。The RectangleF structure that is to the right of the equality operator.

戻り値

指定された 2 つの RectangleF 構造体の XYWidthHeight の各プロパティが等しい場合は true。それ以外の場合は falsetrue if the two specified RectangleF structures have equal X, Y, Width, and Height properties; otherwise, false.

、、 Implicit RectangleFおよびの各メンバーを使用する方法を次のコード例に示します。EqualityThe following code example demonstrates how to use the Implicit, RectangleF and Equality members. この例は、Windows フォームで使用するように設計されています。This example is designed for use with a Windows Form. このコードをフォームに貼り付け、フォームConvertRectangleToRectangleFPaintイベントを処理するときにメソッドをe呼び出しPaintEventArgsて、として渡します。Paste this code into a form and call the ConvertRectangleToRectangleF method when handling the form's Paint event, passing e as PaintEventArgs.
