Serialize XmlNode in an ArrayList

[Jocelyn Kwok]

Hi all,

When I try to use XmlSerializer to serialize an ArrayList
object which contains XmlNode objects, I got
the "InvalidOperationException: The type
System.Xml.XmlElement may not be used in this context."

I can serialize an ArrayList object with string value and
also an XmlNode object individually without problem. I
have no idea why these two together can't work.
Any advice will be appreciated. Thanks.

Here is the sample code I am testing on:

------------------------------------------------
ArrayList oArr = new ArrayList();
XmlDocument oXML = new XmlDocument();

XmlNode oNode1 = oXML.CreateNode
(XmlNodeType.Element, "record", "");
oNode1.InnerText = "abc";

oArr.Add(oNode1);

XmlNode oNode2 = oXML.CreateNode
(XmlNodeType.Element, "record", "");
oNode2.InnerText = "xyz";
oArr.Add(oNode2);

MemoryStream oMem = new MemoryStream();

XmlSerializer xs = new XmlSerializer(typeof(ArrayList));

xs.Serialize(oMem, oArr);

oMem.Position = 0;
ArrayList oresult = (ArrayList)xs.Deserialize(oMem);
