Submitted by Nidhi, on August 29, 2020

Here we will create a list of employees and then sort a list of employees using the OrderBy() method based on salary.

Program:

The source code to sort a list of employees based on salary using Linq is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# program to sort the list of employees 
//based on salary.

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

public class Employee
{
    int ID;
    string Name;
    int Salary;

    public override string ToString()
    {
        return ID + " " + Name+" "+Salary;
    }

    static void Main(string[] args)
    {
        List<Employee> employees = new List<Employee>()
        {
             new Employee {ID=101,   Name="Amit  "    , Salary=4000},
             new Employee {ID=102,   Name="Gautam"    , Salary=6000},
             new Employee {ID=103,   Name="Salman"    , Salary=3000},
             new Employee {ID=104,   Name="Ram   "    , Salary=2000},
        };


        var result = employees.OrderBy(sal => sal.Salary);

        Console.WriteLine("ID  Name   Salary");
        Console.WriteLine("==================");
        foreach (Employee emp in result)
        {
            Console.WriteLine(emp.ToString());
        }
        Console.WriteLine("==================");
    }
}

Output:

ID  Name   Salary
==================
104 Ram    2000
103 Salman 3000
101 Amit   4000
102 Gautam 6000
==================
Press any key to continue . . .

Explanation:

In the above program, we created a class Demo that contains the Main() method. In the Main() method we created a list of employees with fields ID, Name, Salary.

var result = employees.OrderBy(sal => sal.Salary);

The above method call will return the sorted list of employees based on salary.

Console.WriteLine("ID  Name   Salary");
Console.WriteLine("==================");
foreach (Employee emp in result)
{
    Console.WriteLine(emp.ToString());
}
Console.WriteLine("==================");

In the above code, we accessed the employee detail one by one and print on the console screen.
