Inheriting from Classes and Implementing Interfaces

What is Inheritance or How to define Inheritance in C#

Inheritance is the most feature in the object oriented programming.

Inheritance helps not do the repetition of code the same code in the multiple places when dealing with

different classes  which have several features in common and are related to each other. Even they are

different subclasses of the same type, each with its own distinguishing feature

Declared and Define Inherited Class

Parent/Base Class

public Class Employee

{

protected int EmployeeNumber;

protected string EmployeeFirstName;

protected string EmployeeLastname;

protected float Salary;

Protected void WorkAssigned()

{

}

}

//Program Manager class inheriting from  Employee class

Public Class TechnicalManager:Employee

{

Public void ProgramManagerWorkAssigned()

{

}

}

//Program Technical Manager class inheriting from  Employee class

Public Class TechnicalManager:Employee

{

Public void TechnicalManagerWorkAssigned()

{

}

}

example, Program Manager and  Technical Manager ,Engineer are all employees of a Software Company .

When we are writing an application to simulate the Employee Management System, how would you specify that

Program Manager and Technical Manager and Engineer have several features that are the same, but also

other features that are different? For example, they all have an employee reference  employee number and a name and so on, also each one has different responsibilities. When we want to define class of Program Manager and Technical Manager and Engineer each has to be inheriting the employee. So we don’t need to define the common features in all the classes.

In C# inheritance is implemented by using “:”
