Optional elements/attributes in LINQ to XML

[NewsBot]

I'm generating an XML file based on a bunch of properties in my class, and I'm wondering what's the best way to deal with optional elements or attributes.

 

Say I need an XML file like this:

 

 

*

*** Bas

*

 

 

Let's say that the age attribute is optional. Now, suppose I have a class that defines a Name and an Age property. You could generate the XML as follows:

 

Person person = new Person();

 

[...]

 

XDocument document = new XDocument(

***new XElement("persons",

******new XElement("person",

*********new XAttribute("age", person.Age),

*********new XElement("name", person.Name)

******** )

***** )

** );

 

This works fine if Age returns an actual value, but what if it's undefined, or a nullable type, for instance? Is there a way of making sure it only renders the age attribute if Age has an actual value without breaking up that single, smooth block into a mess of multiple if() statements?
