While you could use a serializer - and many times this is the right answer - I personally would use Linq to XML which would allow you to be more flexible on how your XML should look like, i.e. to create the following XML from a collection foos based on your class:

You could use:

var xml = new XElement("Foos", foos.Select( x=> new XElement("foo", 
                                                new XAttribute("Id", x.Id), 
                                                new XAttribute("property1", x.property1), 
                                                new XAttribute("property2", x.property2))));
