LINQ LastOrDefault() Method

In LINQ, LastOrDfeault() method/operator is used to return the last element from the list/collection, and it is the same as LINQ Last() method, and the only difference is that it will return the default value when there is no element in the list/collection.

Syntax of LINQ LastOrDefault() Method

Here is the syntax of using the LINQ LastOrDefault() method to get the last element from the list or default value. In case, if lists returns no elements using the LINQ LastOrDefault() method.

From the above syntax, we are trying to get the last element from the "LastObj" list using LINQ LastOrDefault() method.

Example of LINQ LastOrDefault() Operator in Method Syntax

Here is the example of using the LINQ LastOrDefault() operator in method syntax to get the last element from the list.

using System;
using System. Collections;
using System.Collections.Generic;
using System. Linq;
using System. Text;
using System.Threading.Tasks;

namespace ConsoleApp1
{
    class Program1
    {
        static void Main(string[] args)
        {
//Create an array LISTOBJ having the values from 1 to 5
            int[] LISTOBJ = { 1, 2, 3, 4, 5 };
//Create another array ValObj having no values
            int[] ValObj = { };
/*LastOrDefault() method will fetch the last element 
from the LISTOBJ and store the output in the variable result*/
            int result = LISTOBJ.LastOrDefault();
/*Here LastOrDefault() method is applied on 
the ValObj array and return the result in the variable val*/
            int val = ValObj.LastOrDefault();
            Console.WriteLine("Element from the List1: {0}", result);
            Console.WriteLine("Element from the List2: {0}", val);
            Console.ReadLine();
        }
    }
}

From the above code, we are getting the last element from "LISTOBJ" and "ValObj" lists by using the LINQ LastOrDefault() method.

Example of LINQ LastOrDefault()operator in Query Syntax

Here is the example of using the LINQ LastOrDefault() operator in query syntax to get the last element from the list.

using System;
using System. Collections;
using System.Collections.Generic;
using System. Linq;
using System. Text;
using System.Threading.Tasks;

namespace ConsoleApp1
{
    class Program1
    {
        static void Main(string[] args)
        {
            int[] LISTOBJ = { 1, 2, 3, 4, 5 };
            int[] ValObj = { };
            int result = (from l in LISTOBJ select l).LastOrDefault();
            int val = (from x in ValObj select x).LastOrDefault();
            Console.WriteLine("Element from the List1: {0}", result);
            Console.WriteLine("Element from the List2: {0}", val);
            Console.ReadLine();
        }
    }
}
