Using Overriding and Hiding Methods in C#

Overriding in C#

Extend or replace functionality in the base class

It is required to provide an implementation that has the same meaning as the original method, but has an implementation that is specific to the class. Virtual methods typically provide a default implementation that

inheriting classes are expected to replace with their own code.

To override a method in a subclass, you use the override keyword, as the following

code example shows

public Class Employee

{

protected int EmployeeNumber;

protected string EmployeeFirstName;

protected string EmployeeLastname;

protected float Salary;

Protected virtual void WorkAssigned()

{

}

}

//Program Manager class inheriting from  Employee class

Public Class TechnicalManager:Employee

{

Protected  Override void WorkAssigned()

{

}

}

Hiding Methods in C#

You can define methods in an inherited class that have the same name as methods

in a base class, even if they are not marked as virtual, abstract, or override.

However, this means that there is no relationship between your method and the

original method, and new method hides the original method.

Code

Public Class Employee

{

protected void  ActOn()

{

...

}

}

class Manager : Employee

{

public new void  ActOn()

{

// Hiding he ActOn method in the base class

//Code goes here

}

}
