You can do the following using LINQ:

class Program
{
    static void Main(string[] args)
    {
        List<MyObject> list = new List<MyObject>();

        list.Add(new MyObject() { Age = 12, Name = "ABC" });
        list.Add(new MyObject() { Age = 11, Name = "ABC" });
        list.Add(new MyObject() { Age = 14, Name = "BBC" });

        var sorted = list.OrderBy(mo => mo.Name).ThenBy(mo => mo.Age);

        foreach (var myObject in sorted)
        {
            Console.WriteLine(string.Format("{0} - {1}",
                              myObject.Name, myObject.Age));
        }
    }
}
