Element specified

[Daniel Lidström]

Hi,

it is possible to have a variable of the same name as an element, with the
word `Specified' appended, to control whether the element is serialized or
not. I'm using XmlSerializer, and a class with `Specified' elements may
look like this (in CS):

public class Units
{
public Units() { }
public Units(Metric m) { Metric = m; m_MetricSpecified = true;}
public Units(Imperial i) { Imperial = i; m_ImperialSpecified = true; }

[XmlIgnore] public bool m_MetricSpecified = false;
private Metric m_Metric;
[XmlElement(Type=typeof(Metric),ElementName="Metric ",IsNullable=false)]
public Metric Metric
{
get { return m_Metric; }
set {m_Metric = value; m_MetricSpecified = true; m_ImperialSpecified
= false; }
}

[XmlIgnore] public bool m_ImperialSpecified = false;
private Imperial m_Imperial;

[XmlElement(Type=typeof(Imperial),ElementName="Impe rial",IsNullable=false)]
public Imperial Imperial
{
get { return m_Imperial; }
set { m_Imperial = value; m_MetricSpecified = false;
m_ImperialSpecified = true; }
}
}

I'm not sure the `m_' is allowed on the `Specified' variables. Where can I
find information about this way of specifying elements? I want to do it on
a MC++ class but I can't find any information.
Thanks!
