Linq To XML把对象数组写入xml

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

 

打印出来是这样

 

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

 

这代码真是简单到夸张了
