Trouble Implementing a Sliding Window in Rx

Question

I created a SlidingWindow operator for reactive extensions because I want to easily monitor things like rolling averages, etc. As a simple example, I want to s

Answer 1

Using your original test, with an argument of 3 for count, this gives the desired results:

public static IObservable> SlidingWindow(
    this IObservable source, int count)
{
    return source.Buffer(count, 1)
                 .Where(list => list.Count == count);
}

Testing like this:

var source = Observable.Range(1, 5);
var query = source.SlidingWindow(3);
using (query.Subscribe(i => Console.WriteLine(string.Join(",", i))))
{

}

Output:

1,2,3
2,3,4
3,4,5
