Delegates & Events in C# Explained for Beginners (a little of Event-Driven Development)🔔

[@PatrickGod]

Hey friends! 👋 Patrick here. I wanted to add a quick note to this tutorial. I missed mentioning something important: the built-in generic delegates Func and Action. These are really handy for common scenarios - Func is used for methods that return a value, and Action for those that don't return anything. They often simplify the code compared to custom delegates. I'll make sure to cover these in more detail in a future video. Stay tuned, and happy coding! 😊👨‍💻 Patrick

what sit u explain do u know how explain beginner pig

[@charliehager5458]

You make a very good point that delegates and events are very easy to create and use. Probably under utilized these days. Possibilities for use are endless. Thanks!

[@PatrickGod]

Glad I could help! Thanks for your feedback!

[@Kla-pn4kt]

as a blazor beginner, your explanation is really helpful. Thanks.

[@PatrickGod]

Thanks a lot for your feedback! Glad I could help. 😊

[@horizon6309]

Thank you for the high quality tutorial Patrick, I finally understand the concepts of delegates and events 🙂

[@dasfahrer8187]

I think a much deeper dive is needed for these concepts (why they exist, what problems do they solve, why use them over something simpler and more direct, etc...) as you're getting into more advanced programming and complexity by implementing them. You typically don't use them willy-nilly.

[@agusstiinbt]

Great answer. I also think that delegates and events are only useful in certain situations. In this case in was only useful to learn about them. But not a great example of when you consider using them

[@weamhaleemi4984]

Try learning rabbitMq without them.. it wont work

[@ard-janverhage3577]

Thank you very much, this is the first video I found that explains it this simple.

[@3k1p5]

I really like your way to describe the principles in clear understandable ways. Keep going it's great, thanks.

[@elbadrey]

Much deeper needed, but all of all, thank you

[@Ayymoss]

Question; why should we use explicit delegate over Action for example? I think this has the same functionality, but in one line rather than 2?

[@PatrickGod]

Good point! In the given example, using Action instead of a custom delegate like AchievementUnlockedHandler would indeed simplify the code. The choice here was mainly to demonstrate how custom delegates work and how they can be used to create events. In practical applications, opting for Action is a great idea for its simplicity and brevity, especially for straightforward cases like this. Custom delegates become more useful when you need more descriptive names or complex method signatures. Thanks for pointing this out!

[@Ayymoss]

@@PatrickGod Ah, thank you for clarifying. :)

[@vukasin97]

Very nice explanation 👍 Also that bright light in your background gives a nice fresh look to the video

[@PatrickGod]

Thank you! Funny you're mentioning the bright light. It was actually just the sun shining through the window and I thought it was too bright. 😅

[@philippemaze4562]

One of the clearer tuto I follow about event & delegates...Thank you so much Patrick !

[@shehan.akalanka]

I tried learning events from so many places but they do not explain the basics like you. Really good tutorial. Hope you could create a video about dive into events and delegates.

[@SatyaketuSanjay]

I was searching for this easy explaination! Thank you Patrick!!

[@fryser007]

I'm taking a class on Coursera and the teacher sucks, I have to look up on the youtube some key concepts they explain badly and you sir knock it out of the park. Thank you :)

[@anasabubakar4125]

Aren't Func and Action a built-in delegates ? I think they are easier to understand than creating custom delegates

[@PatrickGod]

Yes, you're absolutely right! Func and Action are indeed built-in generic delegates provided by .NET. They are often more convenient and easier to understand, especially for common scenarios. Func is used for methods that return a value, while Action is for those that don't. Custom delegates are more about understanding the underlying concept and are useful in certain specialized cases. Great observation! 👍

[@shahnawazk]

Very helpful and informative. Thanks and keep it up!

[@PatrickGod]

Thank you so much!

[@maacpiash]

Excellent video. Concise, clear, to the point.

[@KatSanok]

Patrick you do a great job ! Thanks for another nice explaining video.

[@MEGAFOXTERRIER]

Loving these videos! Could you also please make a Blazor Auto Render Mode CRUD Full Course video?

[@38911bytefree]

Thanks man, Im a bit rusted on these concepts .. LOL

[@PatrickGod]

Anytime! Glad I could help! 😊

[@tidianediallo6199]

That's great master Patrick, as a blazor beginer I'm excited? Thank you of lot. The explanations are clear and I hate the next video. also a tutorial on the connection of webApi, signalR and Chatgpt🙂

[@salilphadnis4147]

Very well explained. Thank you so much !

[@moejahi3d3]

Love this! looking forward to the big video. We;re not using .net8 yet but your channel is great to keep up2date or at least in the "know" hehe. Any chance you could make a .net8/identitity server/ Multi tenant video with a central login system shared client but seperate db for each tenant? Been looking into this this week for some idea's hehe.

[@brianking8883]

I like this format.

[@shobhamahadev118]

i understood properly today abt these concepts.

[@PavanTripathi-rj7bd]

Thanks for the wonderful explanation!

[@gouravkanthed3246]

Good Explanation..It would be great if u have included delegates with return type also

[@griffinovermyer9943]

Nice video. Quick question: Would it be a bad idea for your function that invokes the event to invoke then set the delegate to null to prevent a memory leak?

[@yusufdurmaz4839]

can we use that in web?

[@douglasemsantos]

Great explanation! Thank you!

[@FredBCavalheiro]

Excellent explanation. Thanks

[@drtowardssuccess500]

Thank you!

[@orterves]

I prefer to have the class to be coupled with an interface that is injected into the class, that has the callback methods. This forces the object to be instantiated in the data flow with the wiring up already in place. I find that events give the developer too much freedom to create spaghetti data flows, wiring up objects directly, wherever and whenever they want, and causing headaches in finding just where the heck data is going in the app

[@NIKOLAOSGYPAS]

Thanks for the great video Patrick. Is there a way to know if I have subscribed to an event,

[@chaikuanhong]

good work!

[@cjt9150]

Good work. Can you please create a video for custom authentication with cookie/local storage/session storage & without identity

[@imanidioli]

First event explanation that didn't confuse me

[@lean2009]

great lesson!

[@kandycan]

Very good tutorial

[@CyprianLibera]

Very good!

[@DontKnowDontCare]

God is great

[@yuhsiangchen7784]

Thanks

[@srujansanga2689]

I subscribe ! Hoohoooooo

[@pathumkumara4696]

great

[@Brian-nz6ns]

Not well explained...

[@FilthySnob]

Messy bullshit

[@essentia9]

dude I don't know yet what a delegate is and you are throwing into my face async/await. Kind of stupid
