StackOverflowException when serializing

[etienne.maitre@fr.michelin.com]

Hi,

I work against .NET 2.0 using C# 2.0. I am facing a problem trying to
serialize the class foo (given below). Basically, foo can contain
other foos in a list. When I try to create a serializer, using the
test() method below, I get a superb StackOverflowEx ception. I googled
for it but didn't found any answer to why I got this exception and how
to serialize foo.

Any help accepted :-)

Thanks,

public void test()
{
XmlSerializer serializer = new XmlSerializer(t ypeof(foo));
....
}

[Serializable]
public class foo : IEnumerable<foo >
{
// ... some members...
List<foog;

public foo()
{
g = new List<foo>();
}

public IEnumerator<foo GetEnumerator()
{
foreach (foo element in g)
{
yield return element;
}
}

System.Collecti ons.IEnumerator
System.Collecti ons.IEnumerable .GetEnumerator( )
{
return GetEnumerator() ;
}

public void Add(Object e)
{
g.Add(e as foo);
}
}

Re: StackOverflowEx ception when serializing

The problem here comes from the fact that you are implementing
IEnumerable<Ton T itself (in this case foo). You are better of creating a
container class which implements IEnumerable<foo and then serialize that.

Also, you don't need to the Serializable attribute when using XML
Serialization.

Re: StackOverflowEx ception when serializing

Your foo.g member is recursive. You need an object-reference type of
serialization. The easiest fix for you would be to upgrade to WCF
(.NET 3.0) and use the DataContractSer ializer with its support for
object references.
