The easiest way to serialize an attribute with an object is to decorate the property with [XmlAttribute]. Here is a simple example of a class representing your <event> element:

[XmlType(TypeName="event")]
public class Event
{
    [XmlAttribute("id")]
    public int ID { get; set; }
}

You might get some mileage out of the Xsd.exe command line tool. In some cases, the tool can save you a lot of hand-decorating classes for serialization. It can be used in a two-step fashion to:

  1. Generate a XSD validation schema for a sample XML file.
  2. Generate serializable .NET classes based on the XSD schema.
