パラメーター

返品

true XとYのZ、point4D1、およびpoint4D2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 Point4D 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 Point4D structures are equal using the overloaded equality operator.

Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D point2 = new Point4D(15, 40, 60, 75);
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 Point4D structures are equal using the overloaded equality operator.

Dim point1 As New Point4D(10, 5, 1, 4)
Dim point2 As New Point4D(15, 40, 60, 75)
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

Point4D、X、Y、およびZのプロパティの値が同じ場合、2 つのW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Point4D値の比較が失敗する可能性があります。
