Question

I have a list:

List<User> users = getUsers();

The User object has 2 properties I want to sort by:

IsActive
Name

Sort first sort by IsActive, and then sort by name.

So the Active Users will be on the top of the list, sorted by name. Then all the in-active users will be listed (sorted alphabetically).

Is this possible or do I have to break the list up and then merge them?

There are less than 100 items in this List, so performance isn’t really an issue.

Answer 1

Simply use OrderBy and ThenBy. Thanks to Tim Schmelter for his remark. If you use OrderBy, you will get the user with IsActive == false at the top of your list.

var users = getUsers().
    OrderByDescending(u => u.IsActive).
    ThenBy(u => u.Name).
    ToList();

Remember to add to your using directives:

using System.Linq;
