Select random numbers items from list in asp.net c#

In this post I will explain about how to Select random numbers items from list in asp.net c# with example.

Description:

In my previous posts I have explained various topics like Sql Server Coalesce,Method Overloading, Abstract Class in C#

Now in this post, I will explain about how to Select random numbers items from list in asp.net c# with appropriate example.In one of my project I got the requirement to get n random numbers items from list. I was able to get this requirement fulfilled very easily using LINQ. I have made use of LINQ to fulfill this requirement.

Now open Visual Studio , create Console Application and write below line of C#.Net in it.

 class Program
    {
        static void Main(string[] args)
        {
            List<int> ListOfNumber = new List<int>() { 101, 201, 301, 401, 501, 601, 701, 801, 901, 1001, 1101, 1201 };
            List<int> randomNumberList = new List<int>();
            randomNumberList = GetRandomElements(ListOfNumber, 5);

            foreach (var item in randomNumberList)
            {
                Console.WriteLine(item);
            }

            Console.ReadLine();            
        }

        public static List<t> GetRandomElements<t>(IEnumerable<t> list, int elementsCount)
        {
            return list.OrderBy(x => Guid.NewGuid()).Take(elementsCount).ToList();
        }
    }

Now as a output you will get any random 5 integer number(list item) from defined Integer List.
