xml and serilisation with queues??

[spike232]

is it possible to serilise a queue to xml??

i have the following code:

private void SaveToDisk(Queue ErrorList)
{
Stream s  = new FileStream("errors.xml", FileMode.Create);
XmlSerializer b = new XmlSerializer(typeof(Queue));

b.Serialize(s, ErrorList);
s.Close();
}

but it failes with:

An unhandled exception of type 'System.InvalidOperationException' occurred in system.xml.dll

Additional information: There was an error reflecting 'System.Collections.Queue'.

and it points to the line: XmlSerializer b = new XmlSerializer(typeof(Queue));

so can queues not be serlilised ?? I know hashtables cannot so does the same apply here??

Here's a quick example:

using System;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
using System.Collections;

public class SerializeEx
{
	public static void Main()
	{
		string myName = "Bill Gates";
		Queue myQueue = new Queue();
		myQueue.Enqueue(myName);

		FileStream serializeStream = new FileStream(@"c:\MyQueue.dat", FileMode.Create);
		BinaryFormatter bf = new BinaryFormatter();

		bf.Serialize(serializeStream, myQueue);
		serializeStream.Flush();
		serializeStream.Close();

		FileStream retrieveStream = new FileStream(@"c:\MyQueue.dat", FileMode.Open);
		Queue newQueue = (Queue) bf.Deserialize(retrieveStream);
		Console.Write(newQueue.Count);
	}

}
