namespace ConsoleApplication_C_Sharp
{
    class Employee
    {
        public int Salary { get; set; }
        public int age { get; set; }
    }

    class Program
    {
        static void Main(string[] args)
        {
            Employee[] array = new Employee[]
            {
                new Employee(){Salary = 13000, age = 28},

                new Employee(){Salary =  7000, age = 19},
            };

            var OrderedArray = from emp in array
                               orderby emp.Salary descending, emp.age ascending
                               select emp;

            foreach (var emp in OrderedArray)
                Console.WriteLine("Salary: {0}  age: {1}", emp.Salary, emp.age);
        }
    }
}
