Sort a list by an int property in the list differing per entry

Question

I am currently working on a little program for myself, connected to LastFM. Here I can fetch a whole list artists, played in the current week. This is how I first fetch the artists played and store them into a list:

WeeklyArtistChart WeeklyArtists = user.GetWeeklyArtistChart();
//WeeklyArtistChart is a list

Now, let's say each entry in WeeklyArtists[i].Artist has a property named 'Playcount'. I want to sort my list based on that property in descending order, only problem is, I have no idea how!

Your help would be greatly appreciated!

You can use LINQ and Enumerable.OrderByDescending:

var sortedArtists = WeeklyArtists.OrderByDescending(a => a.Artist.Playcount);

If you need a copy of the list with this order, you need to call ToList:

WeeklyArtists = sortedArtists.ToList();

For what it's worth, it's not clear whether it should be `a.Playcount` or `a.Artist.Playcount`. – Kirk Woll Jun 04 '12 at 15:15
@KirkWoll: You're right, it seems that `Artist` is a property, edited my answer. – Tim Schmelter Jun 04 '12 at 15:19
This worked, apologies for being a bit unclear. a.PlayCount was good and worked, and I had to wait before I could mark your post as answer. Thanks! – Infernus Jun 04 '12 at 15:40
