    class Program
    {
        static void printList(List<int> lst)
        {
            //printing elements
            foreach (int item in lst)
            {

            Console.WriteLine();
        }

        static void Main(string[] args)
        {
            //integer list
            List<int> a = new List<int>();

            //adding elements
            a.Add(10);
            a.Add(20);
            a.Add(30);
            a.Add(40);

            printList(a);

            //remove elements
            //will remove 2 elements from index 0 
            a.RemoveRange(0, 2);

            //list after removing the elements
            Console.WriteLine("list elements after removing elements...");
            printList(a);

            //hit ENTER to exit
            Console.ReadLine();
        }
    }
}

Output

list elements...
10 20 30 40 50
list elements after removing elements...
30 40 50
