Question

I need to build a sorter class for a List.

I would like the sort rule or priority to be:

SFC = 1 SSG = 2 SGT = 3 CPL = 4 SPC = 5 ETC…

So when I sort I will get these in the correct order by rank first then by lastname.

List<Person> person = new List<Person>(); 
person.Rank
person.LastName
person.FirstName

ETC…

Please lead me to an article or instruction. Thanks

public enum Rank
{
    SFC = 1, SSG, SGT
}

public class Person
{
    public Rank Rank { get; set; }
    public string Name { get; set; }
}

static void Main(string[] args)
{
    var persons = new List<Person>
    {
        new Person{ Name = "Aaaa", Rank = Rank.SFC },
        new Person{ Name = "Bbbb", Rank = Rank.SFC },
        new Person{ Name = "Aaaa", Rank = Rank.SSG }
    };

    foreach (var person in persons.OrderBy(p => p.Rank).ThenBy(p => p.Name))
    {
        Console.WriteLine("{0} {1}", person.Rank, person.Name);
    }
}

Output:

SFC Aaaa
SFC Bbbb
SSG Aaaa
