This might sound like a silly question, because if you Google "OOPS"
or "OOPS in C#"
you get tons of results. But.
I am aware of concepts of OOP
like abstraction
, inheritance
and what not... But what I want to see is some "practical usable example" of it in programming. Like for polymorphism
you know a practical example is Object.GetType
etc.
Some times if not many, I find myself doing something like at a button click open a connection and do some stuff, this is not OOP
oriented from what I know, I should have a particular entity/class, and it should have a method for the stuff I am doing at button click, and then I should call that method, instead of doing all the stuff at button click.
Another example is that I just found myself loading all the projects that a employee works on, at the txtEmployeeName.Leave
event and then fill the combo for the projects. This is not OOP oriented either, I should have class Employee
, and a method in that which loads all the projects this employee works on, and then I should call that method at txtEmployeeName.Leave
.
When I find or read somewhere (online or whatever) I see things like, Vehicle
is a abstract class, and Car
is a Vehicle
, so it inhered from Vehicle
, and this is Inheritance
. We all understand that, but that's not a practical thing. Another example I found, that if we have a method MakeSound
, and we call it an object Cat
, it will Purr
, but if we call the same method on Dog
, it will Bark
, this is Polymorphism
.
Its good for understanding, but its not "practical" or you should rather say "real programming example". So what I need to know is that are there any good resources (online, books or whatever) where I can read about OOP but not like in exaples I gave in previous paragraph, but some "real world programming example" that would actually have me make my code more OO?
here are some
