static member ( - ) : System.Windows.Media.Media3D.Point3D * System.Windows.Media.Media3D.Point3D -> System.Windows.Media.Media3D.Vector3D

Public Shared Operator - (point1 As Point3D, point2 As Point3D) As Vector3D

Parametry

point1

Point3D

Struktura, na której ma być wykonywana Point3D odejmowanie.

point2

Point3D

Struktura Point3D do odejmowania od .point1

Zwraca

Vector3D

Struktura Vector3D reprezentująca różnicę między point1 i point2.

Przykłady

W poniższym przykładzie pokazano, jak odjąć Point3D strukturę od Point3D struktury za pomocą przeciążonego operatora odejmowania.

// 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"

operationString = "Subtracting a Point3D from a Point3D"
ShowResults(vectorResult.ToString(), syntaxString, resultType, operationString)
