Question

At the XmlSerializer constructor line the below causes an InvalidOperationException which also complains about not having a default accesor implemented for the generic type.

Queue<MyData> myDataQueue = new Queue<MyData>();  // Populate the queue here   XmlSerializer mySerializer =   new XmlSerializer(myDataQueue.GetType());      StreamWriter myWriter = new StreamWriter('myData.xml'); mySerializer.Serialize(myWriter, myDataQueue); myWriter.Close(); 

Answer 1

It would be easier (and more appropriate IMO) to serialize the data from the queue – perhaps in a flat array or List<T>. Since Queue<T> implements IEnumerable<T>, you should be able to use:

List<T> list = new List<T>(queue);
