public:
 static System::Windows::Media::Media3D::Vector3D operator -(System::Windows::Media::Media3D::Point3D point1, System::Windows::Media::Media3D::Point3D point2);

public static System.Windows.Media.Media3D.Vector3D 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 -> System.Windows.Media.Media3D.Vector3D

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

Parâmetros

point1

Point3D

A estrutura Point3D na qual a subtração será executada.

point2

Point3D

A estrutura Point3D para subtrair de point1.

Retornos

Vector3D

Uma estrutura Vector3D que representa a diferença entre point1 e point2.

Exemplos

O exemplo a seguir mostra como usar o operador de subtração sobrecarregado para subtrair uma Point3D estrutura de uma Point3D estrutura.

// 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)
