Point4D.Inequality(Point4D, Point4D) 运算符

定义

比较两个 Point4D 结构是否不相等。Compares two Point4D structures for inequality.

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。The first Point4D structure to compare.

point2
Point4D

要比较的第二个 Point4D 结构。The second Point4D structure to compare.

返回

Boolean

如果 point4D1point4D2XYZW 坐标不同,则为 true;否则为 falsetrue if the X, Y, Z, and W coordinates of point4D1 and point4D2 are different; otherwise, false.

示例

下面的示例演示如何使用重载的不相等运算符来检查两个 Point4D 结构是否不相等。The following example shows how to use the overloaded inequality operator to check whether two Point4D structures are not equal.

// 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

如果两个 Point4D 结构的 X 、、 Y 和属性的值不同,则这两个结构不相等 Z WTwo Point4D structures are not equal if the values of their X, Y, Z, and W properties are different.

由于 Double 值在对其执行算术运算时可能会丢失精度,因此,逻辑上相等的两个值之间的比较 Point4D 可能会失败。Because a Double value can lose precision when arithmetic operations are performed on them, a comparison between two Point4D values that are logically equal might fail.
