Hi Ramesh, Please find the below code. using System; using System.Linq; public class Program { public static void Main() { varnumbers= new int []{3,5,1,5,4}; varresult=numbers.OrderByDescending(x=>x).Distinct().Skip(2).First(); Console.WriteLine(result); } } If the above solution is helpful then, accept the answer.

int[] myArray = new int[] { 0, 1, 2, 3, 13, 8, 5 }; int largest = int.MinValue; int second = int.MinValue; foreach (int i in myArray) { if (i > largest) { second = largest; largest = i; } else if (i > second) second = i; } System.Console.WriteLine(second); OR Try this (using LINQ): int secondHighest = (from number in test orderby number descending select number).Distinct().Skip(1).First()

Hi, Try this code : using System; using System.Collections; public class Program { public static void Main() { int []array={2,11,15,1,7,99,6,85,4}; Array.Sort(array); //sortingarray Array.Reverse(array); //ReverseSortingarrayvalue Console.WriteLine( "SecondHighestValueInArray" +array[1]); foreach (varresult in array) { Console.Write(result+ "" ); //Arrayvalues } } } Reference : https://dotnetfiddle.net/BTsflq

Hi, Write below method in your class, private string GetData(int[] data,int n) { data = data.Distinct().ToArray(); Array.Sort(data); Array.Reverse(data); var result = data.GetValue(n-1); return result.ToString(); } Now, If you want to second highest number in integer array then call this method like below int[] data = new int[10] { 0, 1, 2, 13, 4, 5, 9, 8, 11, 6 }; MessageBox.Show(GetData(data, 2)); If you want third number then you have to pass 3 in GetData method and so on..
