定義

命名空間:

System.Windows.Media.Media3D

組件:

PresentationCore.dll

從 Point4D 結構減去 Point4D 結構，並傳回 Point4D 結構的結果。

public:
 static System::Windows::Media::Media3D::Point4D operator -(System::Windows::Media::Media3D::Point4D point1, System::Windows::Media::Media3D::Point4D point2);

public static System.Windows.Media.Media3D.Point4D operator - (System.Windows.Media.Media3D.Point4D point1, System.Windows.Media.Media3D.Point4D point2);

static member ( - ) : System.Windows.Media.Media3D.Point4D * System.Windows.Media.Media3D.Point4D -> System.Windows.Media.Media3D.Point4D

Public Shared Operator - (point1 As Point4D, point2 As Point4D) As Point4D

參數

point1

Point4D

要減去其中內容的 Point4D 結構。

point2

Point4D

要從 point1 中減去的 Point4D 結構。

傳回

Point4D

傳回 point1 與 point2 之間的差。

範例

下列範例示範如何使用多載減法運算子從 結構減去 Point4D 結構 Point4D 。

// Subtracts a Point4D from a Point4D using the overloaded - operator.
// Returns a Point4D.

Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D point2 = new Point4D(15, 40, 60, 75);
Point4D pointResult = new Point4D();

pointResult = point1 - point2;
// pointResult is equal to (-5, -35, -59, -71) 

// Displaying Results
syntaxString = "pointResult = point1 - point2;";
resultType = "Point4D";
operationString = "Subtracting a Vector3D from a Point4D";
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString);

' Subtracts a Point4D from a Point4D using the overloaded - operator.
' Returns a Point4D.

Dim point1 As New Point4D(10, 5, 1, 4)
Dim point2 As New Point4D(15, 40, 60, 75)
Dim pointResult As New Point4D()

pointResult = point1 - point2
' pointResult is equal to (-5, -35, -59, -71) 

' Displaying Results
syntaxString = "pointResult = point1 - point2"
resultType = "Point4D"
operationString = "Subtracting a Vector3D from a Point4D"
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString)
