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
Parameters
Returns
true
if the X, Y, Z, and W coordinates of point4D1
and point4D2
are different; otherwise, false
.
Examples
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)
Remarks
Two Point4D structures are not equal if the values of their X, Y, Z, and W properties are different.
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.
