Hi Ramesh,
Please find the below code.
usingSystem;
usingSystem.Linq;
publicclassProgram
{
publicstaticvoidMain()
{
varnumbers=newint[]{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 :
usingSystem;
usingSystem.Collections;
publicclassProgram
{
publicstaticvoidMain()
{
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(varresultinarray)
{
Console.Write(result+"");//Arrayvalues
}
}
}

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..
