Public propertyHeightGets or sets the Height of this instance of Size.
Public propertyIsEmptyGets a value that indicates whether this instance of Size is Empty.
Public propertyWidthGets or sets the Width of this instance of Size.

Public methodEquals(Size)Compares a value to an instance of Size for equality.
Public methodStatic memberEquals(Size, Size)Compares two instances of Size for equality.
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeGets the hash code for this instance of Size. (Overrides ValueType.GetHashCode().)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)

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.


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 ;
}
