XmlRootAttribute ignored when serializing class from array

[Dave]

Hello,

I'm trying to solve an XML serialization problem that
appears to me to be be a bug with the XmlSerializer.
Let's say I have a class that looks like this:

[XmlRootAttibute(ElementName="x"]
public class y
{
[XmlAttribute("a")] public string a;
[XmlAttribute("b")] public string b;
}

And I create an array of y using standard syntax:

y [] yArray = new y[2];

If I pass yArray directly to an XmlSerializer object for
serialization, the serializer ignores the
XmlRootAttribute setting on the class and serializes it
as "y" instead of x. Somehting like this:

<yArray>
<y a="1" b="2"/>
<y a="3" b="4"/>
<yArray>

However, if I encapsulate that array into another class,
and then serialize the containing class, it works
properly.

[XmlRootAttribute(ElementName="x_list")]
public class z
{
z()
{
y = new y[2];
}
[XmlElement("x")] public y[] yArray;
}

This serializes y to x the way I want it to:

<x_list>
<x a="1" b="2"/>
<x a="3" b="4"/>
<x_list>

I've tried overriding the XmlSerializer to no avail. Why
doesn't it pick up the XmlRootAttribute from the
declaration of the class y when it is placed into an
array and serialized directly? I'd like to not have to
encapsulate the array into another class.

A slight fix:

[XmlRootAttribute(ElementName="x_list")]
public class z
{
z()
{
yArray = new y[2]; //<<<fixed to yArray.
}
[XmlElement("x")] public y[] yArray;
}
