Answer 1

You can use this for sorting list

namespace GenaricClass
{
    class Employee :IComparable
    {
        public string Name { get; set; }
        public double Salary { get; set; }

        public int CompareTo(Employee other)
        {
            if (this.Salary < other.Salary) return 1;
            else if (this.Salary > other.Salary) return -1;
            else return 0;
        }

        public static void Main()
        {
            List empList = new List()
            {
                new Employee{Name="a",Salary=140000},
                new Employee{Name="b",Salary=120000},
                new Employee{Name="c",Salary=160000},
                new Employee{Name="d",Salary=10000}
            };
            empList.Sort();
            foreach (Employee emp in empList)
            {
                System.Console.Write(emp.Salary +",");
            }
            System.Console.ReadKey();
        }
    }
}
