Size3D.Equals Method (Size3D, Size3D)

Compares two Size3D structures for equality. Two Size3D structures are equal if the values of their X, Y, and Z properties are the same.

Namespace:  System.Windows.Media.Media3D
Assembly:  PresentationCore (in PresentationCore.dll)
public static bool Equals(
	Size3D size1,
	Size3D size2
)

Parameters

size1
Type: System.Windows.Media.Media3D.Size3D

The first Size3D structure to compare.

size2
Type: System.Windows.Media.Media3D.Size3D

The second Size3D structure to compare.

Return Value

Type: System.Boolean
true if instances are equal; otherwise, false.
true if the X, Y, and Z components of size1 and size2 are equal; otherwise, false.

Because Double values can lose precision when arithmetic operations are performed on them, a comparison between two Size3D instances that are logically equal might fail.

The following example shows how to check if two Size3D structures are equal.

private bool size3DEqualityExample()
{

    // Checks if two Size3D structures are equal using the static Equals method.  
    // Returns a Boolean. 

    // Declaring Size3D structure without initializing x,y,z values
    Size3D size1 = new Size3D();

    // Delcaring Size3D structure and initializing x,y,z values
    Size3D size2 = new Size3D(5, 10, 15);
    Boolean areEqual;

    // Assigning values to size1
    size1.X = 2;
    size1.Y = 4;
    size1.Z = 6;

    // checking for equality
    areEqual = Size3D.Equals(size1, size2);

    // areEqual is False 
    return areEqual;

}
