Chaining Observable Subscriptions

Question

Is there a shorthand version of this. I want to call one sequence and then when it is finished call another.

var seq1 = Observable.Range(1, 20);
var seq2 = Observable.Range(21, 20);

seq1.Subscribe(
    i  => Console.WriteLine(i), 
    () => seq2.Subscribe(i => Console.WriteLine(i)));

Answer 1

It's not entirely clear to me what you're trying to do (and I don't have the docs to hand) but is Observables.Concat what you're after?

var seq1 = Observable.Range(1, 20);
var seq2 = Observable.Range(21, 20);
var both = seq1.Concat(seq2);
both.Subscribe(i => Console.WriteLine(i));

(I'm just checking that this actually works :)
