람다

heros.Sort((Hero a, Hero b) => {
    if (a.LIKE && !b.LIKE)
    {
        return -1;
    }
    else if (!a.LIKE && b.LIKE)
    {
        return 1;
    }

    return a.ID.ToString().CompareTo(b.ID.ToString());
});

대리자

heros.Sort(delegate (Hero a, Hero b) {
	if (a.LIKE && !b.LIKE)
    {
        return -1;
    }
    else if (!a.LIKE && b.LIKE)
    {
        return 1;
    }

    return a.ID.ToString().CompareTo(b.ID.ToString());
});

출력

0 - id : 2 / name : Spider Man / like : True
1 - id : 3 / name : Hawk Eye / like : True
2 - id : 5 / name : Ant Man / like : True
3 - id : 1 / name : Iron Man / like : False
4 - id : 4 / name : Doctor Strange / like : False
5 - id : 6 / name : Black Widow / like : False
