LINQ to Lists/Collection

LINQ to Lists/collection means writing the LINQ queries on list or collection. By using LINQ queries on the collection or list, we can filter or sort or remove the duplicates elements with minimal coding.

Syntax of LINQ to Lists or Collections

Here is the syntax of writing the LINQ queries on the list or collection to get the required elements.

var result = from e in objEmp

select new

{

   Name = e.Name,

  Location = e.Location

};

In the above syntax, we have written the LINQ query to get the required data from the "objEmp" collection/list object.

Example of LINQ to Lists/Collections

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

namespace ConsoleApp1
{
    class Programme2
    {
        static void Main(string[] args)
        {
//create object objEmp of class Employee and create a list of the Employee information
           List<Employee> objEmp = new List<Employee>
    ()
    {
    new Employee { EmpId=1,Name = "Akshay", Location="Chennai" },
    new Employee { EmpId=2,Name = "Vaishali", Location="Chennai" },
    new Employee { EmpId=3,Name = "Priyanka", Location="Guntur" },
    new Employee { EmpId=4,Name = "Preeti", Location ="Vizag"},
    };
    //here use the LINQ query to sort or select the element from the collection of data
    var result = from e in objEmp
    where e.Location.Equals("Chennai")
    select new
    {
    Name = e.Name,
    Location = e.Location
    };
    //foreach loop is used to print the value of the 'result' having the output of the LINQ query
    foreach (var item in result)
    {
    Console.WriteLine(item.Name + "\t | " + item.Location);
    }
    Console.ReadLine();
    }

    }
    //create class employee
    class Employee
    {
    public int EmpId { get; set; }
    public string Name { get; set; }
    public string Location { get; set; }
    }
    }

In the above code, we used the LINQ query on the list "objEmp" to get the required elements based on the requirements.
