you can do it by using extension method

public static ObservableCollection ToObservableCollection(this IEnumerable coll)
{
    var c = new ObservableCollection();
    foreach (var e in coll) c.Add(e);
    return c;
}

or you can use this constructor The elements are copied onto the ObservableCollection in the same order they are read by the enumerator of the list.

ObservableCollection collection = new ObservableCollection(yourList);
