[SerializableAttribute]
[TypeConverterAttribute(typeof(SizeConverter))]
public struct Size : IFormattable
XAML Object Element Usage
Copy 
<Size .../>
XAML Attribute Usage
Copy 
<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.

The Size type exposes the following members.

  Name Description
Public method Size Initializes a new instance of the Size structure and assigns it an initial width and height.
Top
  Name Description
Public property Static member Empty Gets a value that represents a static empty Size.
Public property Height Gets or sets the Height of this instance of Size.
Public property IsEmpty Gets a value that indicates whether this instance of Size is Empty.
Public property Width Gets or sets the Width of this instance of Size.
Top
  Name Description
Public method Equals(Object) Compares an object to an instance of Size for equality. (Overrides ValueType.Equals(Object).)
Public method Equals(Size) Compares a value to an instance of Size for equality.
Public method Static member Equals(Size, Size) Compares two instances of Size for equality.
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Gets the hash code for this instance of Size. (Overrides ValueType.GetHashCode.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method Static member Parse Returns an instance of Size from a converted String.
Public method ToString Returns a String that represents this Size object. (Overrides ValueType.ToString.)
Public method ToString(IFormatProvider) Returns a String that represents this instance of Size.

  Name Description
Public operator Static member Equality Compares two instances of Size for equality.
Public operator Static member Narrowing(Size to Vector) Explicitly converts an instance of Size to an instance of Vector.
Public operator Static member Narrowing(Size to Point) Explicitly converts an instance of Size to an instance of Point.
Public operator Static member Inequality Compares two instances of Size for inequality.

  Name Description
Explicit interface implemetation Private method IFormattable.ToString This type or member supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code.

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.

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

C#
C++
VB
Copy 

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 ;
}
