Point3D.Inequality(Point3D, Point3D) 运算符

定义

命名空间:

System.Windows.Media.Media3D

程序集:

PresentationCore.dll

比较两个 Point3D 结构是否不相等。

public:
 static bool operator !=(System::Windows::Media::Media3D::Point3D point1, System::Windows::Media::Media3D::Point3D point2);

public static bool operator != (System.Windows.Media.Media3D.Point3D point1, System.Windows.Media.Media3D.Point3D point2);

static member op_Inequality : System.Windows.Media.Media3D.Point3D * System.Windows.Media.Media3D.Point3D -> bool

Public Shared Operator != (point1 As Point3D, point2 As Point3D) As Boolean

参数

point1

Point3D

要比较的第一个 Point3D 结构。

point2

Point3D

要比较的第二个 Point3D 结构。

返回

Boolean

如果 point1 和 point2 的 X、Y 和 Z 坐标不相等，则为 true；否则为 false。

示例

以下示例演示如何使用重载的不相等运算符检查两个 Point3D 结构是否不相等。

// Checks if two Point3Ds are not equal using the overloaded inequality operator.

Point3D point1 = new Point3D(10, 5, 1);
Point3D point2 = new Point3D(15, 40, 60);
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 Point3Ds are not equal using the overloaded inequality operator.

Dim point1 As New Point3D(10, 5, 1)
Dim point2 As New Point3D(15, 40, 60)
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

如果两X个结构的值不同，Y并且属性不同，则Z两Point3D个结构不相等。

由于 Double 当对它们执行算术运算时，值可能会丢失精度，因此在逻辑上相等的两 Point3D 个实例之间的比较可能会失败。
