 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

返品

true XとYのZ、point1、およびpoint2座標が等しい場合は 。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

Point3D、X、およびYプロパティの値が同じ場合、2 つのZ構造体が等しくなります。

Double値に対して算術演算を実行すると精度が失われる可能性があるため、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。
