In this example, we will learn how to implement multilevel inheritance using C# program?
Submitted by Nidhi, on August 20, 2020 [Last updated : March 21, 2023]

Here we will create a C# program to demonstrate the multi-level inheritance. Here we will create Human, Man, and Employee classes to implement multilevel inheritance.

C# program to demonstrate the example of multilevel inheritance

The source code to demonstrate the multi-level inheritance in C# is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

// program to demonstrate the multi-level inheritance in C#

using System;

class Human
{
    public string name;
    public Human(string na)
    {
        name = na;
    }
}

class Man : Human
{
    public int age;
    public Man(int age, string name):base(name)
    {
        this.age = age;
    }
}

class Employee: Man
{
    public int emp_id;
    public int emp_salary;

    public Employee(int id, int salary,string name,int age):base(age,name)
    {
        emp_id = id;
        emp_salary = salary;
    }
    public void Print()
    {
        Console.WriteLine("Emp ID:      " + emp_id      );
        Console.WriteLine("Emp Name:    " + name        );
        Console.WriteLine("Emp Salary:  " + emp_salary  );
        Console.WriteLine("Emp Age:     " + age         );
    }
    static void Main(string[] args)
    {
        Employee emp = new Employee(101, 1000, "Rahul", 31);
        emp.Print();
    }
}

Output

Emp ID:      101
Emp Name:    Rahul
Emp Salary:  1000
Emp Age:     31
Press any key to continue . . .

Explanation

In the above program, we created three classes Human, Man, and Employee. Here we inherited Human class into Man class and then Man class into Employee class.  Every class contains a constructor to initialize data members. Here we also created one more method Main() in the Employee class. Here we created an object of Employee class and print the Employee detail on the console screen.
