Question

I have an object named game which has a property called channels (which is comma separated since a game can relate to more then one channel).

I also have a channel object, which contains a property called isActive.

What I need, is a way to get all the games that have active channels.

I started writing this:

var oGames = games.AllActive.Where(
    g => !g.StateProperties.Channels.Contains(
        channels.All.Where(c => c.StateProperties.IsActive).ToArray()
    );

but got blocked… anyone can help me ?

Answer 1

var oGames = games.AllActive
    .Where(g => g.StateProperties.Channels.Split(',')
                 .Intersect(channels.Where(c => c.StateProperties.IsActive)
                                    .Select(c => c.Name)).Any());

I’d strongly recommend moving away from a csv of channel names, and instead store a reference to them.

This would simplify the code quite a lot. Using a dictionary mapping strings to channels would also help.
