I am trying to make a class in C# on the basis of the following XML code:
<?xml version="1.0" encoding="ISO-8859-1"?> <Catalog> <Book> <Title><TitleA>ORK</TitleA></Title> <Author>J.D. Salinger</Author> <Publisher>Little Brown and Company</Publisher> <Pub_Date>1951</Pub_Date> </Book> <Book> <Title><TitleA>NAA</TitleA></Title> <Author>Jan</Author> <Publisher>Jans forlag</Publisher> <Pub_Date>2011</Pub_Date> </Book> </Catalog> I have looked on this thread XML to c# Question, but I have not been able to solve the problem. My c# code looks like this:
public class Catalog { public BookClass Book { get { return Book; } set { Book = value; } } } public class BookClass { public TitleClass Title { get { return Title; } set { Title = value; } } public string Author { get { return Author; } set { Author = value; } } public string Publisher { get { return Publisher; } set { Publisher = value; } } public string Pub_Date { get { return Pub_Date; } set { Pub_Date = value; } } } public class TitleClass { public string TitleA { get { return TitleA; } set { TitleA = value; } } } I get the following error message:
An unhandled exception of type 'System.StackOverflowException' occurred in CADtoXML.exe
I have tried to use the XML serializer with no luck; I think it has something to do with the fact that there is at sub sub element in the XML code. Book -> Title -> TitleA. Any help will be greatly appreciated.
Update 1:
I have tried this solution before, but then i get this error: Object reference not set to an instance of an object. The code i am running in the main class is the following
Catalog book1 = new Catalog(); book1.Book.Author = "A"; book1.Book.Publisher = "A"; book1.Book.Pub_Date = "A"; And after this I import them to a list and use the Serializer to make a new XML file.
Don't know if this can help.
Update 2:
Like this:
BookClass book1 = new BookClass(); book1.Author = "A"; book1.Publisher = "A"; book1.Pub_Date = "A"; book1.Title.TitleA = "A"; I still have the same problem. I can't make the book1.Title.TitleA, then I have to do this:
TitleClass book2 = new TitleClass(); book2.TitleA = "A"; But now they are two different objects, book1 and book2.... And they are based on two different classes, and therefore I cannot use this (list the object and afterwards make it an XML code:
List<BookClass, TitleClass> books = new List<BookClass, TitleClass>() { book1, book2 }; XmlSerializer x = new XmlSerializer(typeof(List<BookClass, TitleClass>), new XmlRootAttribute("TEST")); x.Serialize(Console.Out, books); I want to do that, so I get my XML code, with the sub sub element, like presented in my first post.
Thanks for the help so far ;)
