Question

I have an IEnumerable collection and want to pump items into another collection at one second itervals. How do I achieve this? There are so many new extension methods. I don’t what to use where yet.

Answer 1

list1.ToObservable() // Convert list1 to Observable
    .Zip(
        Observable.Interval(TimeSpan.FromSeconds(1)), // Zip it with an observable that ticks every second
        (list, timerList) => list // select list1 only
    ).
Subscribe((item) =>
{
    list2.Add(item); // on each tick, add an item to list2
});
