Parametrar

point1
Point3D

Strukturen Point3D som subtraktion ska utföras på.

point2
Point3D

Strukturen Point3D som ska subtraheras från point1.

Returer

Vector3D

En Vector3D struktur som representerar skillnaden mellan point1 och point2.

Exempel

I följande exempel visas hur du använder den överbelastade subtraktionsoperatorn för att subtrahera en Point3D struktur från en Point3D struktur.

// 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
