LINQ Empty Method

In LINQ, the Empty method or operator is used to return the empty sequence of the collection.

Syntax of LINQ Empty Method

Here is the syntax of the LINQ Empty method to generate the collection with an empty sequence.

In the above syntax, we defined the Empty() method to generate an empty sequence.

Example of LINQ Empty Method

Here is the example of the LINQ Empty Method to generate the collection, which contains the empty sequence.

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)
        {
/*here Enumerable.Empty<int>() method will generate the 
    zero elements. Here we do not want to return any value*/
            var result1 = Enumerable.Empty<int>();
            foreach (var item in result1)
            {
                Console.WriteLine(item);
            }
                Console.ReadLine();
        }
    }
}

In the above example, we defined the Empty method to generate an empty sequence. If we run the above example, we will get empty results. This is the way how we can use the LINQ Empty() method to generate the empty sequence of the collection.
