例

次の例は、オーバーロードされた減算演算子を使用して、Point3D構造体からPoint3D構造体を減算する方法を示しています。

// Subtracts a Point3D from a Point3D using the overloaded - operator.
// Returns a Vector3D.

Point3D point1 = new Point3D(10, 5, 1);
Point3D point2 = new Point3D(15, 40, 60);
Vector3D vectorResult = new Vector3D();

vectorResult = point1 - point2;
// vectorResult is equal to (-5, -35, -59)

// Displaying Results
syntaxString = " vectorResult = point1 - point2;";
resultType = "Vector3D";
operationString = "Subtracting a Point3D from a Point3D";
ShowResults(vectorResult.ToString(), syntaxString, resultType, operationString);

' Subtracts a Point3D from a Point3D using the overloaded - operator.
' Returns a Vector3D.

Dim point1 As New Point3D(10, 5, 1)
Dim point2 As New Point3D(15, 40, 60)
Dim vectorResult As New Vector3D()

vectorResult = point1 - point2
' vectorResult is equal to (-5, -35, -59)

' Displaying Results
syntaxString = " vectorResult = point1 - point2"
resultType = "Vector3D"
operationString = "Subtracting a Point3D from a Point3D"
ShowResults(vectorResult.ToString(), syntaxString, resultType, operationString)
