I have a class with numerous Nullable
Implement the IXmlSerializable
interface on your class. You can then handle special cases such as nullables in the ReadXML
and WriteXML
methods. There's a good example in the MSDN documentation page..
class YourClass : IXmlSerializable
{
public int? Age
{
get { return this.age; }
set { this.age = value; }
}
//OTHER CLASS STUFF//
#region IXmlSerializable members
public void WriteXml (XmlWriter writer)
{
if( Age != null )
{
writer.WriteValue( Age )
}
}
public void ReadXml (XmlReader reader)
{
Age = reader.ReadValue();
}
public XmlSchema GetSchema()
{
return(null);
}
#endregion
}
I had a similar problem with some code I was working on, and I decided just to use a string for the property I was serializing and deserializing. I ended up with something like this:
[XmlAttribute("Age")]
public string Age
{
get
{
if (this.age.HasValue)
return this.age.Value.ToString();
else
return null;
}
set
{
if (value != null)
this.age = int.Parse(value);
else
this.age = null;
}
}
[XmlIgnore]
public int? age;
