Introduction

Going to introduce Sorting for Arrays,List.

Objective

As we know if we have multiple fields for sorting in array or list then we have lot of difficulties.
Just using  Lambda expression we can solve this issue very easily.

Using the code

using System;

```using System.Collections.Generic;
using System.Linq;

namespace Sort_Multiple_Fields
{
public class Emplyoee
{
public string fName { get; set; }
public string lName { get; set; }
public DateTime jDate { get; set; }

public Emplyoee(DateTime date, string fname, string lname)
{
this.fName = fname;
this.lName = lname;
this.jDate = date;
}
}

class Program
{

static void Main(string[] args)
{
List<Emplyoee> person = new List<Emplyoee>();
person.Add(new Emplyoee(new DateTime(2007, 1, 1), "Lalit", "Khanna"));
person.Add(new Emplyoee(new DateTime(2008, 2, 2), "Amit", "Singh"));
person.Add(new Emplyoee(new DateTime(2008, 2, 2), "Amit", "Chauhan"));
person.Add(new Emplyoee(new DateTime(2009, 1, 1), "Dot", "Net"));

person = person.OrderBy(sortFname => sortFname.fName).ThenBy(sortLastName => sortLastName.lName).ThenBy(sortJdate => sortJdate.jDate).ToList();

foreach (Emplyoee e in person)
{
Console.WriteLine(e.fName +" "+e.lName);
}
