Point3D.Inequality(Point3D, Point3D) 運算子

定義

比較兩個 Point3D 結構是否相等。

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

參數

point1
Point3D

要比較的第一個 Point3D 結構。

point2
Point3D

要比較的第二個 Point3D 結構。

傳回

如果 point1point2XYZ 座標不同則為 true,否則為 false

範例

下列範例示範如何使用多載不等比較運算子來檢查兩 Point3D 個 結構是否不相等。

// 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)

備註

如果 、 XYZ 屬性的值不同,則兩 Point3D 個 結構不相等。

由於 Double 在算數運算上執行算數運算時,值可能會失去精確度,因此邏輯上相等的兩 Point3D 個實例之間的比較可能會失敗。
