LINQ Except Method

In LINQ, the Except method or operator is used to return only the elements from the first collection, which are not present in the second collection.

Here is the pictorial representation of the LINQ Except method.

As we see in the above figure, it will return the element from the first collection, which does not exist in the second collection.

Syntax of LINQ Except Method

The syntax of using the LINQ Except method to get the elements from the first list which does not exist in the second list.

From the above syntax, we are comparing two lists "arr1","arr2" and getting elements using the Except() method.

Example of LINQ Except Method

Here is the example of the LINQ Except method to get the element from the first collection.

using System;
using System. Collections;
using System.Collections.Generic;
using System. Linq;
using System. Text;
using System.Threading.Tasks;
namespace ConsoleApp1
{
    class Programme2
    {
        static void Main(string[] args)
        {
//create an array 'a' and 'b' type of string having the values
            string[] a = { "Rohini", "Suresh", "Sateesh", "Praveen" };
            string[] b = { "Madhav", "Sushmitha", "Sateesh", "Praveen" };
//Except method is used to return the value which does not exist in the second list 
            var result = a.Except(b);
            foreach (var item in result)
            {
                Console.WriteLine(item);
            }
                Console.ReadLine();
        }
    }
}
