# Size3D Struct

## Definition

Data structure that describes the size of a three-dimensional object.

``public value class Size3D : IFormattable``
``````[System.ComponentModel.TypeConverter(typeof(System.Windows.Media.Media3D.Size3DConverter))]
public struct Size3D : IFormattable``````
``````[System.ComponentModel.TypeConverter(typeof(System.Windows.Media.Media3D.Size3DConverter))]
[System.Serializable]
public struct Size3D : IFormattable``````
``````[<System.ComponentModel.TypeConverter(typeof(System.Windows.Media.Media3D.Size3DConverter))>]
type Size3D = struct
interface IFormattable``````
``````[<System.ComponentModel.TypeConverter(typeof(System.Windows.Media.Media3D.Size3DConverter))>]
[<System.Serializable>]
type Size3D = struct
interface IFormattable``````

## Examples

This example shows how to determine if two Size3D structures are equal using the Size3D static Equals method.

The following code illustrates how to check Size3D structures for equality. The Size3D structures are declared and assigned values. The Equals method is then used to determine if the two 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;
}
``````

## Remarks

Size3D and Rect3D are not typically used in XAML, because no settable properties exist in the WPF 3D object model that use those types.

## Constructors

 Initializes a new instance of the Size3D structure.

## Properties

 Gets a value that represents an empty Size3D structure. Gets a value that indicates whether this Size3D structure is empty. Gets or sets the X value of this Size3D structure. Gets or sets the Y value of this Size3D structure. Gets or sets the Z value of this Size3D structure.

## Methods

 Determines whether the specified object is a Size3D structure and whether the X, Y and Z properties of the specified Object are equal to the X, Y and Z properties of this Size3D structure. Compares two Size3D structures for equality. Compares two Size3D structures for equality. Two Size3D structures are equal if the values of their X, Y, and Z properties are the same. Returns a hash code for this Size3D structure. Converts a String representation of a three-dimensional size structure into the equivalent Size3D structure. Creates a String representation of this Size3D structure. Creates a String representation of this Size3D structure.

## Operators

 Compares two Size3D structures for equality. Two Size3D structures are equal if the values of their X, Y, and Z properties are the same. Converts this Size3D structure into a Point3D structure. Converts this Size3D structure into a Vector3D structure. Compares two Size3D structures for inequality. Two Size3D structures are not equal if the values of their X, Y and Z properties are different.
