Size3D.X Property

Definition

Gets or sets the X value of this Size3D structure.

``````public:
property double X { double get(); void set(double value); };``````
``public double X { get; set; }``
``member this.X : double with get, set``
``Public Property X As Double``

Property Value

The X value of this Size3D structure. The default value is `0`.

Examples

The following example shows how to check if two Size3D structures are equal. It also shows how to assign values to a Size3D structure when the structure is being declared and after the structure has been declared.

``````// 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();

// Declaring 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

// Displaying Results
syntaxString = "areEqual = Size3D.Equals(size1, size2);";
resultType = "Boolean";
operationString = "Checking if two Size3D structures are equal";
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString);
``````
``````' Checks if two Size3D structures are equal using the static Equals method.
' Returns a Boolean.

' Declaring Size3D structure without initializing x,y,z values
Dim size1 As New Size3D()

' Declaring Size3D structure and initializing x,y,z values
Dim size2 As New Size3D(5, 10, 15)
Dim areEqual As Boolean

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

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

' areEqual is False

' Displaying Results
syntaxString = "areEqual = Size3D.Equals(size1, size2)"
resultType = "Boolean"
operationString = "Checking if two Size3D structures are equal"
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString)
``````

Remarks

The X, Y, and Z values must be non-negative.

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