C# Program to Sort a List of Employees Based on Salary using LINQ

• Last Updated : 06 Dec, 2021

Given a list of employees, now we sort the list of employees according to their salary using LINQ. So to this task, we use the OrderBy() method. This method is used to sort the elements of the specified sequence in ascending order.

Example:

Input:
{id = 101, Name = Rohit, Salary = 50000, Department = HR}
{id = 104, Name = Rohit, Salary = 10000, Department = Development}
{id = 106, Name = Rohit, Salary = 80000, Department = HR}
{id = 108, Name = Rohit, Salary = 20000, Department = Development}
Output:
{id = 104, Name = Rohit, Salary = 10000, Department = Development}
{id = 108, Name = Rohit, Salary = 20000, Department = Development}
{id = 101, Name = Rohit, Salary = 50000, Department = HR}
{id = 106, Name = Rohit, Salary = 80000, Department = HR}

Approach:

1. Create a list of employees along with their id, name, salary, and department.

2. Now sort the employee’s list according to their salary using the OrderBy() method.

var result_set = Geeks.OrderBy(sal => sal.Emp_Salary);

Or we can also sort the list using the order OrderBy clause of LINQ

var result_set = from emp in Geeks orderby emp.Emp_Salary select emp;

3. Display the sorted list using foreach loop.

Example 1:

C#

 // C# program to sort a list of employees// based on salary. Using OrderBy() methodusing System;using System.Linq;using System.Collections.Generic;  class Geek{      int emp_id;string Emp_Name;int Emp_Salary;string Emp_Department;  static void Main(string[] args){          // Geeks data    List Geeks = new List()    {        new Geek{emp_id = 101, Emp_Name = "arjun",                  Emp_Salary = 50000, Emp_Department = "ABC"},        new Geek{emp_id = 102, Emp_Name = "bheem",                  Emp_Salary = 65000, Emp_Department = "DEF"},        new Geek{emp_id = 103, Emp_Name = "krishna",                  Emp_Salary = 45000, Emp_Department = "ABC"},        new Geek{emp_id = 104, Emp_Name = "Ram",                  Emp_Salary = 20000, Emp_Department = "DEF"},        new Geek{emp_id = 105, Emp_Name = "kiran",                  Emp_Salary = 70000, Emp_Department = "DEF"},        new Geek{emp_id = 106, Emp_Name = "karna",                  Emp_Salary = 50000, Emp_Department = "ABC"},    };        // We have sorted the data using OrderBy() command    var result_set = Geeks.OrderBy(sal => sal.Emp_Salary);          // Display the sorted result    foreach (Geek emp in result_set)    {        Console.WriteLine(emp.emp_id + " " +                           emp.Emp_Name + " " +                           emp.Emp_Salary + " " +                           emp.Emp_Department);    }}}
Output
104 Ram    20000 DEF
103 krishna 45000 ABC
101 arjun   50000 ABC
106 karna 50000 ABC
102 bheem 65000 DEF
105 kiran  70000 DEF

Example 2:

C#

 // C# program to sort a list of employees// based on salary. Using OrderBy() methodusing System;using System.Linq;using System.Collections.Generic;  class Geek{      int emp_id;string Emp_Name;int Emp_Salary;string Emp_Department;  static void Main(string[] args){          // Geeks data    List Geeks = new List()    {        new Geek{emp_id = 201, Emp_Name = "Sumit",                  Emp_Salary = 50000, Emp_Department = "ABC"},        new Geek{emp_id = 202, Emp_Name = "Rohan",                  Emp_Salary = 65000, Emp_Department = "DEF"},        new Geek{emp_id = 203, Emp_Name = "Mohit",                  Emp_Salary = 45000, Emp_Department = "ABC"},        new Geek{emp_id = 204, Emp_Name = "Sonam",                  Emp_Salary = 20000, Emp_Department = "DEF"},        new Geek{emp_id = 205, Emp_Name = "Shive",                  Emp_Salary = 70000, Emp_Department = "DEF"},    };        // We have sorted the data using OrderBy linq clause    var result_set = from emp in Geeks orderby emp.Emp_Salary select emp;          // Display the sorted result    foreach (Geek emp in result_set)    {        Console.WriteLine(emp.emp_id + " " +                           emp.Emp_Name + " " +                           emp.Emp_Salary + " " +                           emp.Emp_Department);    }}}

Output

204 Sonam 20000 DEF
203 Mohit 45000 ABC
201 Sumit 50000 ABC
202 Rohan 65000 DEF
205 Shive 70000 DEF
