Cast LINQ result to ObservableCollection

Question

The fact that it is a LINQ result might perhaps not be relevant for the question, but I\'m mentioning it anyway - since this is the context which has resulted in this questi

Answer 1

Just use:

ObservableCollection x = new ObservableCollection(enumerable);

That will do the required copying. There's no way of observing changes to the live query - although the idea of an ObservableQuery is an interesting (though challenging) one.

If you want an extension method to do this, it's simple:

public static ObservableCollection ToObservableCollection
    (this IEnumerable source)
{
    if (source == null)
    {
        throw new ArgumentNullException("source");
    }
    return new ObservableCollection(source);
}
