I am running this code so accordingly it should result in the unmatched items between the 2 arrays

The arr3 is returning me 5.



var arr1 = new int[] { 3, 4, 5 }; // Declare int array
            var arr2 = new int[] { 3, 4};
            var arr3=arr1.Except(arr2);

            Console.WriteLine(arr3.ToString());
            Console.ReadLine();


For arr1 can i first define it as empty...like below and then add a list to this since the items are generated dynamically..but its giving me an error on compile time

var arr1 = new int[] {};

Hi,

You can use generics here-

List<int> myInts = new List<int>();
myInts.Add(5);
myInts.Add(10);
myInts.Add(11);
myInts.Count // = 3

Open in new window


And you can get the difference by list1 = list1.Except(list2).ToList(); code.
