Compares two Point3D structures for equality.

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

public static bool Equals(
	Point3D point1,
	Point3D point2
)

Parameters

point1
Type: System.Windows.Media.Media3D.Point3D

The first Point3D structure to compare.

point2
Type: System.Windows.Media.Media3D.Point3D

The second Point3D structure to compare.

Return Value

Type: System.Boolean

true if the X, Y, and Z values for point1 and point2 are equal; otherwise, false.

Two Point3D structures are equal if the values of their X, Y, and Z properties are the same.

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 check whether two Point3D structures are equal.

// Checks if two Point3D structures are equal using the static Equals method.

Point3D point1 = new Point3D(10, 5, 1);
Point3D point2 = new Point3D(15, 40, 60);
Boolean areEqual;

areEqual = Point3D.Equals(point1, point2);
// areEqual is False	

//Displaying Results
syntaxString = "areEqual = Point3D.Equals(point1, point2);";
resultType = "Boolean";
operationString = "Checking if 3D two points are equal";
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString);
