enum ParticipantTypes<br /> {<br /> Author = 0,<br /> Editor<br /> } </p> <p>class BookParticipant<br /> {<br /> public string FirstName;<br /> public string LastName;<br /> public ParticipantTypes ParticipantType;<br /> } </p> <p>BookParticipant[] bookParticipants = new[] {<br /> new BookParticipant {FirstName = "Joe", LastName = "Rattz",<br /> ParticipantType = ParticipantTypes.Author},<br /> new BookParticipant {FirstName = "Ewan", LastName = "Buckingham",<br /> ParticipantType = ParticipantTypes.Editor}<br /> }; </p> <p>XElement xBookParticipants =<br /> new XElement("BookParticipants",<br /> bookParticipants.Select(p =><br /> new XElement("BookParticipant",<br /> new XAttribute("type", p.ParticipantType),<br /> new XElement("FirstName", p.FirstName),<br /> new XElement("LastName", p.LastName)))); </p> <p>Console.WriteLine(xBookParticipants);  

打印出来是这样

<BookParticipants><br /> <BookParticipant type="Author"><br /> <FirstName>Joe</FirstName><br /> <LastName>Rattz</LastName><br /> </BookParticipant><br /> <BookParticipant type="Editor"><br /> <FirstName>Ewan</FirstName><br /> <LastName>Buckingham</LastName><br /> </BookParticipant><br /> </BookParticipants>  

这代码真是简单到夸张了
