1st program is a List program, uses the FindIndex() method and it is executing well.
2nd program is an Array program also uses FindIndex() method and it is not executing. How to make it executing.
1st program
using System;
using System.Collections.Generic;
class Program
{
static void Main()
{
List<int> elements = new List<int>() { 10, 20, 31, 40 };
int oddIndex = elements.FindIndex(x => x % 2 != 0);
Console.WriteLine(oddIndex);//2
Console.ReadKey();
}
}
2nd program
using System;
class Program
{
static void Main()
{
int[] array = { 15, 6, 7, 16 };
int index = array.FindIndex(x => x == 6);
Console.WriteLine("{0}", index);
Console.ReadKey();
}
}
