Custom sort logic in OrderBy using LINQ

Question

What would be the right way to sort a list of strings where I want items starting with an underscore \'_\', to be at the bottom of the list, otherwise everything is alphabet

Answer 1

If you want custom ordering, but don't want to supply a comparer, you can have it - sql style:

autoList
.OrderBy(a => a.StartsWith("_") ? 2 : 1 )
.ThenBy(a => a);
