Vector3D.Equality Operator

Compares two Vector3D structures for equality.

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

public static bool operator ==(
	Vector3D vector1,
	Vector3D vector2


Type: System.Windows.Media.Media3D.Vector3D
The first Vector3D structure to compare.
Type: System.Windows.Media.Media3D.Vector3D
The second Vector3D structure to compare.

Return Value

Type: System.Boolean
true if the X, Y, and Z components of vector1 and vector2 are equal; false otherwise.

Two Vector3D structures are equal if the values of their X, Y, and Z properties are the same.

Vector3D values are described using Double values. Because the value of a Double can lose precision when operated upon, a comparison between two Vector3D values that are logically equal might fail.

The following example shows how to use the overloaded equality operator to check if two Vector3D structures are equal.

// Checks if two Vector3D structures are equal using the overloaded equality operator.

Vector3D vector1 = new Vector3D(20, 30, 40);
Vector3D vector2 = new Vector3D(45, 70, 80);
Boolean areEqual;

areEqual = (vector1 == vector2);
// areEqual is False
