Tnq so much Bangaraju sir
you are explaination is Execellent

[<modifiers>] interface <Name>
{
- Abstract Member Declarations here
}

Generally a class inherits from another class to consume the members of its parent, where as if a class is inheriting from an interface it is to implement the members of its parent.

Every abstract method of an interface should be implemented by the child class of he interface.

Interface : contains only Abstract Methods ( Methods with out method body).

Fantastic explanation, Sir.


Regards

Your explanation is of next level Sir !!!!!!

"Abstract class can contain both abstract and non-abstract methods. But the Interface contain only Abstract methods"👏👏Excellentt!! None of the websites have given this much of clarity about interfaces and abstract classes. Simply amazing👏👏👏👏

Perfect Teaching 👌

THANK YOU SIR .

very nicely each and every ponint cover. 😀

There is a mistake. The default access specifier for the class is internal not private.

multiple inheritance.

Which template should we select to create an interface in visual studio

abay typest kiya perha raha hai. aik hi baat ko khud hi flasekahta hai. phir wo ho repaeat kerta hai.

Beginning with C# 8.0, an interface may define a default implementation for members. It can also contain static fields and so on. So what then is the essential difference between abstract classes and interfaces? Maybe inheritance, because a class can inherit only one class but multiple interfaces?

Good explain

Bangar Raju great banda hai yar

Mr bangar raju, you told that what is interface, very nice. Can you please explain why is interface? Why we need it?

Update: C# 8.1 onwards Interfaces also has Method body to give a common implementation for the classes deriving that interface.

sir your explanation is so good by heart thanks also want more teaching can it possible? kindly pls reply

in c# 2008 I get an error when I use void Interface1.Add(int x, int y) Class so and so does not contain a definition for "Add" and no extension method.......ect Are you missing a using directive...... But public void Add(int x, int y) is working fine. I like your videos, I have learned a lot ..Thanks again

Actually i am from Sri Lanka and i fall in love with this play list

thank you for ur beautiful video

One of the best explanations I have ever watched. Thanks 1000 times.

Very interesting demo Sir , thank you.

Thanks a lot sir 🙏🇮🇳

Dear Sir, Please make a video on very important interview questions.
1. An Interface does not contain any implementation, only declarations. so what is the benefit of interface?
2. Use of delegate.
3. Use of abstract class.

Really appreciated 👍

Awesome sir. You comparing every other concepts too. So that is more understandable.

Thank you so much . it help me lot

You are a good teacher but I can only understand %80 of what you say, we need captions. Even automatic captions would work, as it did for me in the abstract video.

Sir, do u provide hard copy of these tutorial?? I need it ... Hope you will reply..😊😊

Awesome quality of teaching, guys if you have time ever then visit once and try to grab live knowledge. Thank you Naresh Team to make such a wonderful session available for us. and specially thanks to Bangar Raju Sir. :)

Default scope for class is internal,Not private.!

for me ty is not enough to say

Sir Very good Explanations, your examples are very good for making the concepts understated-able... Keep Posting the Videos. it is really helping us...

very very gooooooooooooooooooooood

Sir please upload more vedio of c# series

The default scope for the class is INTERNAL or otherwise to be declared public. Private, protected and protected internal can be applied only to nested classes.

i liked your all videos..the explanation with examples is superb...

Sir please tell me which software you use for s screen recording and sound recording

Hii

is there needs to mention scope in interface??

Nice explination it helps a lot thanks..

Sir I was asked what is explicit interface. I got confused and could not answer it. Can you explain the same sir?
