LINQ result to ObservableCollection

By samjayander thiagarajan

How to select the result of a ObservableCollection from Linq back to Generic ObservableCollection instead of Generic List.

Consider you are using a LINQ over a ObservableCollection<Entity> and you want to get the Result Items as a list.

using .ToList(), you will end up in a List<Enity> and not ObservableCollection<Entity>

To solve this, you can have a Extension method like this  and just use .ToObservableCollection<Entity>.

    public static class ExtensionMethods
    {
        public static ObservableCollection<T> ToObservableList<T>(this IEnumerable<T> data)
        {
            ObservableCollection<T> dataToReturn = new ObservableCollection<T>();

            foreach (T t in data)
                dataToReturn.Add(t);

            return dataToReturn;
        }
  }

A bit Handy. Thats it!!!
