# Point.Equality(Point, Point) 演算子

## 定義

2 つの Point オブジェクトを比較します。Compares two Point objects. この結果は、2 つの X オブジェクトの Y プロパティと Point プロパティの値が等しいかどうかを示します。The result specifies whether the values of the X and Y properties of the two Point objects are equal.

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

left
Point

right
Point

#### 戻り値

`true` および XY 値と `left` 値が等しい場合は `right`。それ以外の場合は `false``true` if the X and Y values of `left` and `right` are equal; otherwise, `false`.

## 例

Equality 演算子の使用方法と、Size または2つの整数から Point を構築する方法を次のコード例に示します。The following code example demonstrates how to use the Equality operator and how to construct a Point from a Size or two integers. また、X プロパティと Y プロパティの使用方法も示します。It also demonstrates how to use the X and Y properties. この例は、Windows フォームと共に使用するように設計されています。This example is designed to be used with Windows Forms. `Button1`という名前のボタンを含むフォームにコードを貼り付け、`Button1_Click` メソッドをボタンの Click イベントに関連付けます。Paste the code into a form that contains a button named `Button1`, and associate the `Button1_Click` method with the button's Click event.

``````private:
void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
// Construct a new Point with integers.
Point Point1 = Point(100,100);

// Create a Graphics object.
Graphics^ formGraphics = this->CreateGraphics();

// Construct another Point, this time using a Size.
Point Point2 = Point(System::Drawing::Size( 100, 100 ));

// Call the equality operator to see if the points are equal,
// and if so print out their x and y values.
if ( Point1 == Point2 )
{
array<Object^>^temp0 = {Point1.X,Point2.X,Point1.Y,Point2.Y};
formGraphics->DrawString( String::Format( "Point1.X: "
"{0},Point2.X: {1}, Point1.Y: {2}, Point2.Y {3}", temp0 ), this->Font, Brushes::Black, PointF(10,70) );
}
}
``````
``````private void Button1_Click(System.Object sender, System.EventArgs e)
{

// Construct a new Point with integers.
Point Point1 = new Point(100, 100);

// Create a Graphics object.
Graphics formGraphics = this.CreateGraphics();

// Construct another Point, this time using a Size.
Point Point2 = new Point(new Size(100, 100));

// Call the equality operator to see if the points are equal,
// and if so print out their x and y values.
if (Point1 == Point2)
{
formGraphics.DrawString(String.Format("Point1.X: " +
"{0},Point2.X: {1}, Point1.Y: {2}, Point2.Y {3}",
new object[]{Point1.X, Point2.X, Point1.Y, Point2.Y}),
this.Font, Brushes.Black, new PointF(10, 70));
}

}
