C# interfaces 🐟

C# interfaces tutorial example explained

#C# #interfaces #interface

using System;

// interface = defines a "contract" that all the classes inheriting from should follow

// An interface declares "what a class should have"
// An inheriting class defines "how it should do it"

// benefits = security + multiple inheritance + "plug-and-play"

Interface declares: "What a class should have"

An inheriting class defines: "How it should do it"
Chef's kiss of an explanation, thanks sir

[BlueHat]

Your explanations are one of the clearest and easiest to remember ones I've ever come across. Great job!

[Obalanserad]

My teacher has spent hours confusing this for me. This was so clear

[jacobsonokoro]

I have seen other videos, and this is the best explanation i've seen so far. Thanks a lot. I've subscribed.

[rhr-pw]

Zero BS, straight to the point. After watching your video I inmediately understood how to refactor my existing programs using Interfaces. Thank you very much!

[sgn]

getting into programing for game development as I have always been fascinated by it and your vids are the best I have found. You explain it in such a way that actually helps me learn. Most coding videos on YouTube are so hard to listen to as they don't know how to communicate their skills properly. But I thank you for doing such a good job with it as your videos help me a lot.

[liorlior]

Your ability to explain such complicated things so simply is simply amazing to me.
Thank you for a great channel and quality content!

[Cherry-jcbo]

in just 5 min whole concept is clear...thanks a lot..

[dzulanimashau]

I have spent YEARS trying to understand this. today, i fully understood this in 5 minutes . WOW

[mojzi]

In an hour i'm writing an exam based on this. 10 minutes ago I knew shit about interfaces, now I know all I need. Huge thanks goes to this man! 🙏🏿

[gaminggoddessaria]

This helped me so much I was so confused having to do this at my internship and I got the hang of it in 5 minutes because you explained this so well! Thank thank you

[Delmas.]

After days of studying and going through lecture material on this topic, I was still clueless until your 5' tutorial came to the rescue. 🙏

[jayanders]

2:16 Rabbit... rabbit... equals new... Rabbit. Made me lol. Excellent video.

[mysteryultragames]

My guy just made an intermediate programming concept seem look like a beginner programming concept. Thank you Mr.Chad.

[despahotaru]

Most simple explanation I have seen on interfaces. Thank you!

[blasterxt]

Dude this is one of the best explanations of the interface of c#

[xejdikmiecik]

After years, your tutorials still the best

IPrey for you 🙏

Spent a couple of years learning C# online through YouTube videos, I learned alot to the point where I created a console program to make pizzas from scratch. The program I wrote allowed me to input keys to the console that allowed option selection. I learned that through Michael Hadley's Intro to Programming tutorials.

However I struggled like a muddabucka with a few things to this day. Interfaces being one them. Today I am on Unity exploring real game design, and their lesson courses are amazing. All the C# know-how I learned proved worth it, because I am flying through the courses - because Unity's documentation doe alot of work for you. But there was a course that used IEnumerators in Unity.

Sure I understood what the IEnumerator as for - but I still never understood Interfaces themselves. Now I do thanks to your video. And i's such a clear and easy concept i feel so dumb tonot have grasped them before.

But thanks man! ... I mean... Bro.

God bless people like you who distill this information down to what is necessary without waffling on.
