Point4D.Equals Method (Object)

Determines whether the specified Object is a Point4D structure and if the X, Y, Z, and W properties of the specified Object are equal to the X, Y, Z, and W properties of this Point4D structure.

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

public override bool Equals (
	Object o
public boolean Equals (
	Object o
public override function Equals (
	o : Object
) : boolean
You cannot use methods in XAML.



The Object to compare.

Return Value

true if instances are equal; otherwise, false. true if o (the passed Object) is a Point4D structure and is identical with this Point4D structure; false otherwise.

If o (the passed object) is not a Point4D structure, this method returns false.

Because the value of Doubles can lose precision when arithmetic operations are performed on them, a comparison between two Doubles that are logically equal might fail.

The following example shows how to check whether an Object and a Point4D structure are equal.

// Compares an Object and a Point4D for equality using the non-static Equals method.

Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D point2 = new Point4D(15, 40, 60, 75);
Boolean areEqual;

areEqual = point1.Equals(point2);
// areEqual is False.  point2 is a Point4D structure, but it is not equal to point1.    

// Displaying Results
syntaxString = "areEqual = point1.Equals(point2);";
resultType = "Boolean";
operationString = "Checking if two 3D points are equal";
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString);
