Why my ObservableCollection serialization doesn't work?

Question

I\'m trying to serialize and deserialize this ObservableCollection:

public class DataCollection : ObservableCollection
{
}

public class Data : I

1. Your Data class must have a parameter less constructor, otherwise XmlSerializer will never be able to create instance of Data.
2. Instead of storing DataCoollection, you should store and retrieve Data[], it's easier without having to do anything else.
3. While storing, you can call ToArray method to get Data[] and use typeof(Data[]) for serializer.
4. While reading you can read the array and add items into your collection.
