List.Reverse(int index, int count) method with example in C#

C# List.Reverse(int list, int check) technique: Here, we will find out about the Reverse(int record, int tally) strategy for List with example.

C# List.Reverse(int list, int check) Method

List.Reverse(int list, int check) technique is utilized to switch the predetermined components in the rundown.

Syntax:

    void List<T>.Reverse(int index, int count);

Parameter: It acknowledges two parameters 1) file – a beginning situation from where we need to turn around the components and 2) tally – all outnumber of components from the file.

Return value: It returns nothing – it’s profits type is void

Example:

    int list declaration:
    List<int> a = new List<int>();

    adding elements:
    a.Add(10);
    a.Add(20);
    a.Add(30);
    a.Add(40);
    a.Add(50);
    
    reversing elements:
    //reverse 3 list elements from index 1
    a.Reverse(1,3);
    
    Output:
    10 40 30 20 50

C# Example to invert indicated list components utilizing List.Reverse(int file, int check) Method

namespace Test
{
    class Program
    {
        static void printList(List<int> lst)
        {
            //printing elements
            foreach (int item in lst)
            {
                Console.Write(item + " ");
            }
            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);
            a.Add(50);

            if (a.Count > 0)
            {
                //print the list
                Console.WriteLine("list elements...");
                printList(a);
            }
            else
            {
                Console.WriteLine("list is empty");
            }

            //reverse 3 list elements from index 1
            a.Reverse(1,3);

            //list after reversing the elements
            if (a.Count > 0)
            {
                Console.WriteLine("list elements after reversing elements...");
                printList(a);
            }
            else
            {
                Console.WriteLine("list is empty");
            }

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

Output

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