Definition

Namespace:

System.Windows

Assembly:

Implements a structure that is used to describe the Size of an object.

public value class Size : IFormattable

[System.ComponentModel.TypeConverter(typeof(System.Windows.SizeConverter))]
public struct Size : IFormattable

[<System.ComponentModel.TypeConverter(typeof(System.Windows.SizeConverter))>]
type Size = struct
    interface IFormattable

Public Structure Size
Implements IFormattable

Examples

The following example demonstrates how to use a Size structure in code.

virtual Size MeasureOverride(Size availableSize) override
{
    Size^ panelDesiredSize = gcnew Size();

    // In our example, we just have one child. 
    // Report that our panel requires just the size of its only child.
    for each (UIElement^ child in InternalChildren)
    {
        child->Measure(availableSize);
        panelDesiredSize = child->DesiredSize;
    }
    return *panelDesiredSize ;
}

protected override Size MeasureOverride(Size availableSize)
{
    Size panelDesiredSize = new Size();

    // In our example, we just have one child. 
    // Report that our panel requires just the size of its only child.
    foreach (UIElement child in InternalChildren)
    {
        child.Measure(availableSize);
        panelDesiredSize = child.DesiredSize;
    }

    return panelDesiredSize ;
}

Protected Overrides Function MeasureOverride(ByVal availableSize As System.Windows.Size) As System.Windows.Size
    Dim panelDesiredSize As Size = New Size()
    ' In our example, we just have one child. 
    ' Report that our panel requires just the size of its only child.
    For Each child As UIElement In InternalChildren
        child.Measure(availableSize)
        panelDesiredSize = child.DesiredSize
    Next
    Return panelDesiredSize
End Function

Remarks

Size is particularly useful because it describes both the Height and Width of an object. Size is used extensively by the layout system to arrange and measure elements.

XAML Attribute Usage

<object property="width,height"/>  

XAML Values

width
A value greater than or equal to 0 that specifies the Width of the Size structure.

height
A value greater than or equal to 0 that specifies the Height of the Size structure.

Constructors

Size(Double, Double)

Initializes a new instance of the Size structure and assigns it an initial width and height.

Properties

Empty	Gets a value that represents a static empty Size.
Height	Gets or sets the Height of this instance of Size.
IsEmpty	Gets a value that indicates whether this instance of Size is Empty.
Width	Gets or sets the Width of this instance of Size.

Methods

Equals(Object)	Compares an object to an instance of Size for equality.
Equals(Size)	Compares a value to an instance of Size for equality.
Equals(Size, Size)	Compares two instances of Size for equality.
GetHashCode()	Gets the hash code for this instance of Size.
Parse(String)	Returns an instance of Size from a converted String.
ToString()	Returns a String that represents this Size object.
ToString(IFormatProvider)	Returns a String that represents this instance of Size.

Operators

Equality(Size, Size)	Compares two instances of Size for equality.
Explicit(Size to Point)	Explicitly converts an instance of Size to an instance of Point.
Explicit(Size to Vector)	Explicitly converts an instance of Size to an instance of Vector.
Inequality(Size, Size)	Compares two instances of Size for inequality.

Explicit Interface Implementations

IFormattable.ToString(String, IFormatProvider)

This type or member supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code.
