C# Program to Print the Employees Whose Last Character of Name is ‘n’ Using LINQ

  • Last Updated : 16 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 study how to print the list of employee’s names whose last character of the name is ‘n’ using LINQ. 

Example:

Input : List of Employees:
       {{id = 101, name = "Sravan", age = 12},
        {id = 102, name = "deepu",  age = 15},
        {id = 103, name = "manoja", age = 13},
        {id = 104, name = "Sathwik", age = 12},
        {id = 105, name = "Saran",  age = 15}}
Output: {{id = 105, name = "sravan", age = 15},
        {id = 105, name = "Saran",  age = 15}}
   
Input: List of Employees:
      {{id = 102, name = "deepu",  age = 15},
       {id = 103, name = "manoja", age = 13}}
Output: No Output

Approach:

To find the list of employees whose name ends with ‘n’ character follow the following steps:

  • Create a list of employees with four variables(Id, name, department, and team).
  • Iterate through the employee details and get the employee details by choosing employee name ends with ‘n’ using the following queries:
IEnumerable<Employee> Query = from emp in employees
                              where emp.name[emp.name.Length - 1] == 'n'
                              select emp;
  • Now call the ToString() method.
  • Display the employee details.

Example:

C#




// C# program to display the list of employees
// whose last character of the name is 'n' 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
  
// Create a class with four variables
// employee id, name, and department
class Employee{
      
int id;
string name;
string department;
  
// To string method
public override string ToString()
{
    return id + " " + name + " " + department;
}
  
// Driver code
static void Main(string[] args)
{
      
    // Create list of employees with 5 data
    List<Employee> emp = new List<Employee>()
    {
        new Employee{ id = 101, name = "Sravan"
                      department = "Development" },
        new Employee{ id = 102, name = "deepu",  
                      department = "HR" },
        new Employee{ id = 103, name = "manoja"
                      department = "Development" },
        new Employee{ id = 104, name = "Sathwik"
                      department = "Development" },
        new Employee{ id = 105, name = "Saran"
                      department = "HR" }
    };
      
    // Condition to get employee name ends with 'n'
    IEnumerable<Employee> result = from e in emp
                                   where e.name[e.name.Length - 1] == 'n'
                                   select e;
  
    Console.WriteLine("ID  Name  Department");
    Console.WriteLine("++++++++++++++++++++");
      
    // Iterating the employee data to display 
    // By calling the to string method
    foreach (Employee x in result)
    {
        Console.WriteLine(x.ToString());
    }
}
}

Output:

ID  Name  Department
++++++++++++++++++++
101 Sravan Development
105 Saran HR
