Point4D.Inequality(Point4D, Point4D) 運算子

定義

比較兩個 Point4D 結構是否相等。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

參數

point1
Point4D

要比較的第一個 Point4D 結構。The first Point4D structure to compare.

point2
Point4D

要比較的第二個 Point4D 結構。The second Point4D structure to compare.

傳回

Boolean

如果 point4D1point4D2XYZW 座標不同則為 true,否則為 falsetrue if the X, Y, Z, and W coordinates of point4D1 and point4D2 are different; otherwise, false.

範例

下列範例顯示如何使用多載的不等比較運算子來檢查兩個 Point4D 結構是否不相等。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)

備註

Point4D如果其 XYZ 和屬性的值不同,則兩個結構不相等 WTwo Point4D structures are not equal if the values of their X, Y, Z, and W properties are different.

因為在對 Double 其執行算數運算時,值可能會遺失精確度,所以在邏輯上相等的兩個值之間的比較 Point4D 可能會失敗。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.
