    1. If you're working with non-generic IEnumerable you can do it this way:

      public ObservableCollection Convert(IEnumerable original)
{
    return new ObservableCollection(original.Cast());
}


    2. If you're working with generic IEnumerable you can do it this way:
      


      public ObservableCollection Convert(IEnumerable original)
{
    return new ObservableCollection(original);
}

      3. 

    3. If you're working with non-generic IEnumerable but know the type of elements, you can do it this way:
      


      public ObservableCollection Convert(IEnumerable original)
{
    return new ObservableCollection(original.Cast());
}

      4.
