Subtraction(Point3D, Vector3D)	从一个 Vector3D 结构中减去另一个 Point3D 结构并以 Point3D 结构返回结果。

Subtraction(Point3D, Point3D)

从一个 Point3D 结构中减去另一个 Point3D 结构并以 Vector3D 结构返回结果。

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

参数

point1

Point3D

要执行减法的 Point3D 结构。

point2

Point3D

要从 point1 中减去的 Point3D 结构。

返回

Vector3D

Vector3D 结构，它表示 point1 与 point2 之间的差值。

示例

下面的示例演示如何使用重载减法运算符从 Point3D 结构中减去 Point3D 结构。

// 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)

Public Shared Operator - (point As Point3D, vector As Vector3D) As Point3D

参数

point

Point3D

要从中减去 vector 的 Point3D 结构。

vector

Vector3D

要从 point 中减去的 Vector3D 结构。

返回

Point3D

已更改的 Point3D 结构，它是从 vector 中减去 point 所得的结果。

示例

下面的示例演示如何使用重载减法运算符从 Point3D 结构中减去 Vector3D 结构。

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