How to Sort a List (C#)

Take this class as example.

public class Player
{
    public string Name { get; set; }
    public int Total { get; set; }

    public Player(string name, int total)
    {
        Name = name;
        Total = total;
    }
}

Creating the list.

List<Player> lst = new List<player>();
lst.Add(new Player("John", 100));
lst.Add(new Player("Smith", 120));
lst.Add(new Player("Cait", 97));
lst.Add(new Player("Irene", 100));
lst.Add(new Player("Ben", 100)); 
lst.Add(new Player("Deniel", 88));

Sort By Using List<t>.Sort() Method

Sort by single element "Total" in ascending order:

lst.Sort(delegate(Player x, Player y)
{
    return x.Total.CompareTo(y.Total);
});

Sort by single element "Total" in descending order:

lst.Sort(delegate(Player x, Player y)
{
    return y.Total.CompareTo(x.Total);
});

Sort by multiple elements:

lst.Sort(delegate(Player x, Player y)
{
    // Sort by total in descending order
    int a = y.Total.CompareTo(x.Total);

    // Both player has the same total.
    // Sort by name in ascending order
    if (a == 0)
        a = x.Name.CompareTo(y.Name);

    return a;
});

Sort By Using Linq

Sorting by using Linq requires less syntax.

var result1 = lst.OrderBy(a => a.Total);

var result3 = lst.OrderBy(a => a.Total).ThenBy(a => a.Name);

var result2 = lst.OrderByDescending(a => a.Total).ThenByDescending(a => a.Name);
