c# - linq group by contiguous blocks

Question

Let's say I have following data:

Time Status
10:00 On
11:00 Off
12:00 Off
13:00 Off
14:00 Off
15:00 On
16:00 On

How could I group that using Linq into something like

[On, [10:00]], [Off, [11:00, 12:00, 13:00, 14:00]], [On, [15:00, 16:00]]

Answer 1

Create a GroupAdjacent extension, such as the one listed here.

And then it's as simple as:

var groups = myData.GroupAdjacent(data => data.OnOffStatus);
