ViewsC# Sort Array by multiple different conditions
I got an array which contains items of the object 'Person'
I need to have the special people on top (those sorted by Id) and the nonspecial people below (those sorted alphabetically). It should look like this:
Is there a way of sorting it like this without having to split the list, sort it individually and then merging it back together?

First you can OrderBy by Special (note that false < true) and then you can use condition within ThenBy like this:
var result = persons
.OrderBy(person => person.Special != "Yes")
.ThenBy(person => person.Special == "Yes" ? person.Id : 0)
.ThenBy(person => person.Special == "Yes" ? "" : person.Name);

A non-linq version:
list.Sort((a, b) =>
{
if (a.Special != b.Special)
{
return a.Special ? -1 : 1;
}
return a.Name.CompareTo(b.Name);
});
