Point3D.Inequality Operator

Compares two Point3D structures for inequality.

Namespace:  System.Windows.Media.Media3D
Assembly:  PresentationCore (in PresentationCore.dll)

public static bool operator !=(
	Point3D point1,
	Point3D point2


Type: System.Windows.Media.Media3D.Point3D

The first Point3D structure to compare.

Type: System.Windows.Media.Media3D.Point3D

The second Point3D structure to compare.

Return Value

Type: System.Boolean
true if the X, Y, and Z coordinates of point1 and point2 are different; otherwise, false.

Two Point3D structures are not equal if the values of their X, Y, and Z properties are different.

Because Double values can lose precision when arithmetic operations are performed on them, a comparison between two Point3D instances that are logically equal might fail.

The following example shows how to use the overloaded inequality operator to check whether two Point3D structures are not equal.

// 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);
