C# Program to Print the Employees Whose Salary is Between 6000 and 8000 Using LINQ

  • Last Updated : 18 Oct, 2021

LINQ is known as Language Integrated Query and it is introduced in .NET 3.5. It gives the ability to .NET languages to generate queries to retrieve data from the data source. It removes the mismatch between programming languages and databases and the syntax used to create a query is the same no matter which type of data source is used. In this article, we will get the employee details whose salary is between 6000 and 8000 using LINQ.

Example:

Input:
List of employees:
      {{emp_id = 101, emp_name = "bobby", emp_age = 12, emp_salary = 2000}}
Output:
No Output
      
Input:
List of employees:
     {{emp_id = 101, emp_name = "bobby",  emp_age = 12, emp_salary = 8900},
      {emp_id = 102, emp_name = "deepu",  emp_age = 15, emp_salary = 7000},
      {emp_id = 103, emp_name = "manoja", emp_age = 13, emp_salary = 6700}}
Output:
      {{emp_id = 102, emp_name = "deepu",  emp_age = 15, emp_salary = 7000},
       {emp_id = 103, emp_name = "manoja", emp_age = 13, emp_salary = 6700}}

Approach:

To display the employee details whose salary is between 6000 and 8000 follow the following approach:

  1. Create a list of employees with four variables (Id, name, department, and salary)
  2. Iterate through the employee details by using where function and get the employee details by choosing employee salary between 6000 and 8000.
  3. Select the details which are between 6000 and 8000
  4. Call the ToString method
  5. Display the employee details

Example:

C#




// C# program to display the details of the employee's
// whose salary is between 6000 and 8000 
// using LINQ.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
  
class Employee{
      
// Declare 4 variables - id,age, name and salary
int emp_id; 
string emp_dept;
string emp_name;
int emp_salary;
  
// Get the to string method that returns id,
// name, age and salary
public override string ToString()
{
    return emp_id + " " + emp_name + " "
           emp_dept + " " + emp_salary;
}
  
// Driver code
static void Main(string[] args)
{
      
    // Declare a list variable 
    List<Employee> emp = new List<Employee>()
    {
          
        // Create 3 employee details
        new Employee{ emp_id = 101, emp_name = "bobby"
                      emp_dept = "HR", emp_salary = 8900  },
        new Employee{ emp_id = 102, emp_name = "deepu"
                      emp_dept = "Development", emp_salary = 7000 },
        new Employee{ emp_id = 103, emp_name = "manoja"
                      emp_dept = "HR", emp_salary = 6700 }};
                        
    // Iterate the Employee by selecting Employee id
    // greater than 101 using where function
    IEnumerable<Employee> Query = 
    from employee in emp where employee.emp_salary >= 6000 &&
    employee.emp_salary <= 8000 select employee;
  
    // Display employee details
    Console.WriteLine("ID  Name  Department Salary");
    Console.WriteLine("+++++++++++++++++++++++++++");
    foreach (Employee e in Query)
    {
          
        // Call the to string method
        Console.WriteLine(e.ToString());
    }
}
}

Output:

ID  Name  Department Salary
+++++++++++++++++++++++++++
102 deepu Development 7000
103 manoja HR 6700
