Serialize nullable fields from an object c#

Question

I am trying to serialize an object that has nullable fields. If the field doesn't have any data in it the field is dropped from the serialized output. Any suggests on how to work around this? Is there a way to specify that nullable empty fields still get carried over?

This occurs when "propertyname_specified = false"

If the field is null, what did you expect to see in the XML? — John Saunders

You must apply XmlElementAttribute:

[XmlElement(IsNullable = true)]
public string DummyField { get; set; }

This is how nulls are communicated in .NET XML serialization, the element doesn't exist.
