Point4D.Inequality(Point4D, Point4D) 运算符

定义

命名空间:

System.Windows.Media.Media3D

程序集:

PresentationCore.dll

比较两个 Point4D 结构是否不相等。

public:
 static bool operator !=(System::Windows::Media::Media3D::Point4D point1, System::Windows::Media::Media3D::Point4D point2);

public static bool operator != (System.Windows.Media.Media3D.Point4D point1, System.Windows.Media.Media3D.Point4D point2);

static member op_Inequality : System.Windows.Media.Media3D.Point4D * System.Windows.Media.Media3D.Point4D -> bool

Public Shared Operator != (point1 As Point4D, point2 As Point4D) As Boolean

参数

point1

Point4D

要比较的第一个 Point4D 结构。

point2

Point4D

要比较的第二个 Point4D 结构。

返回

Boolean

如果 point4D1 和 point4D2 的 X、Y、Z 和 W 坐标不同，则为 true；否则为 false。

示例

下面的示例演示如何使用重载不相等运算符检查两 Point4D 个结构是否不相等。

// Checks if two Point4Ds are not equal using the overloaded inequality operator.

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

areNotEqual = (point1 != point2);
// areNotEqual is True

// Displaying Results
syntaxString = "areNotEqual = (point1 != point2);";
resultType = "Boolean";
operationString = "Checking if two 3D points are not equal";
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString);

' Checks if two Point4Ds are not equal using the overloaded inequality operator.

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

areNotEqual = (point1 <> point2)
' areNotEqual is True

' Displaying Results
syntaxString = "areNotEqual = (point1 != point2)"
resultType = "Boolean"
operationString = "Checking if two 3D points are not equal"
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString)

注解

Point4D如果两个结构的值不同，YZW则两X个结构不相等。

由于当对它们执行算术运算时，值 Double 可能会丢失精度，因此在逻辑上相等的两 Point4D 个值之间的比较可能会失败。
