Point3D.Equality(Point3D, Point3D) 演算子

public:
 static bool operator ==(System::Windows::Media::Media3D::Point3D point1, System::Windows::Media::Media3D::Point3D point2);

public static bool operator == (System.Windows.Media.Media3D.Point3D point1, System.Windows.Media.Media3D.Point3D point2);

static member ( = ) : System.Windows.Media.Media3D.Point3D * System.Windows.Media.Media3D.Point3D -> bool

Public Shared Operator == (point1 As Point3D, point2 As Point3D) As Boolean

パラメーター

戻り値

Boolean

point1 および point2 の X、Y、Z の各座標が等しい場合は true。それ以外の場合は false。

例

次の例は、オーバーロードされた等値演算子を使用して、2 つの Point3D 構造体が等しいかどうかを確認する方法を示しています。

// Checks if two Point3Ds are equal using the overloaded equality operator.

Point3D point1 = new Point3D(10, 5, 1);
Point3D point2 = new Point3D(15, 40, 60);
Boolean areEqual;

areEqual = (point1 == point2);
// areEqual is False

// Displaying Results
syntaxString = "areEqual = (point1 == point2);";
resultType = "Boolean";
operationString = "Checking if two 3D points are equal";
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString);

' Checks if two Point3Ds are equal using the overloaded equality operator.

Dim point1 As New Point3D(10, 5, 1)
Dim point2 As New Point3D(15, 40, 60)
Dim areEqual As Boolean

areEqual = (point1 = point2)
' areEqual is False

' Displaying Results
syntaxString = "areEqual = (point1 == point2)"
resultType = "Boolean"
operationString = "Checking if two 3D points are equal"
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString)

注釈

2 つの Point3D 構造体は、それらの X値、 Y および Z プロパティが同じ場合に等しくなります。

算術演算を実行すると、値の精度が失われる可能性があるため Double 、論理的に等しい 2 つの Point3D インスタンス間の比較が失敗する可能性があります。
