29. C# - Delegates

In this video, we'll be talking about delegates in C#. Delegates are a powerful mechanism you can use in your code to improve the readability and performance of your code.
We'll explore how delegates work, and how to use them to simplify your code and make it easier to understand. We'll also look at some common patterns you may encounter when working with delegates, and how to best use them in your code.

One of the best explanations about Delegates I ever watched... Thanks!

[@DotNetHow]

Thank you for watching

[@ecerejo]

5 minutes of pure simplicity is all it took to get rid of all my confusion about this subject. A big THANK YOU.

[@DotNetHow]

Thank you!

[@patrevizani]

omfg, just watched 5 or 6 videos on delegates, found this to be the best one, not just for the explanation, but mainly due to the good exemples on how to actually use. thanks a lot!

[@DotNetHow]

Thanks for the feedback. I am glad you liked it.

[@redblade79x]

Thank you! I just spent the last 2 hours trying to wrap my head around delegates and you explained it perfectly within 5 minutes. Amazing!

[@DotNetHow]

You are welcome. I am glad you liked them

[@niko6646]

spent a hours on this and finally got it 3 mins into your video. thank you sir

[@DotNetHow]

You are welcome. I am glad you found it useful!

[@DotNetHow]

I'm glad the video was helpful to you!

[@faithyintii8457]

I like how your videos are short and straight to the point... thanks man

[@DotNetHow]

Thanks for your feedback

Delegates are like managers: nobody needs them.

[@psycho.2u]

You can't call a private method in another class directly. But by using delegate, you can..

[@jopsthegamer1975]

@@psycho.2u You're right. Also delegates are really important in asynchronous programming(Threading)

[@DotNetHow]

Thanks Raj

[@DotNetHow]

Thanks for the update

[@anomalii7720]

@@psycho.2u That is not why it is private.

[@thibno8260]

Your tutorial put an end to my 2-hour wandering on the Internet looking for the meaning of "delegate" in C# !

[@palesarapapali1698]

thank you for making this topic simple to understand, i struggled a lot trying to understand delegates. This was very helpful

[@DotNetHow]

Thank you

[@glu_max]

The only bad thing about this video is inappropriately loud music. Other than that - great job, thank you!

[@0xF81]

Yeah, there could be even no music at all

[@iswilson]

Simple and easy to understand. Thank you very much

[@DotNetHow]

Thank you for watching

[@Oom_Sakkie]

Good quality programming tutorials make granddaddy's prostate feel alive again

[@andrewqolta9642]

I have never understood this delegate concept before. Now I got it. thank you.

[@DotNetHow]

You are welcome

[@fredyuldashev]

Dude, i watched the top instructors on youtube..inlcuding Mosh, Tim Corey you fucking name it...they all confused the fuck out of me, yet your video is only 5 minutes and it was sooooo CLEAR!

[@DotNetHow]

Thank you for your feedback, Fred! I am glad I was able to help! :)

[@SK_TnT]

great.. nicely explained in simple way & short time

[@DotNetHow]

Thank you

[@antalsergiu7649]

Very clear explanation, thanks a lot !

[@SWIFTzTrigger]

What a brilliant explanation, thank you

[@ismetince]

The best explanation. Thank you

Thank you!

[@fulgencejuniorlohore854]

Thank you for this great tutorial!

[@DotNetHow]

Thanks for watching

[@imadabab]

Thanks a lot for the great explanation. In other words, a delegate is a variable of type method, and this variable can be a parameter in another method.

[@DotNetHow]

True

[@imadabab]

@@DotNetHow Your explanations are extremely helpful and excellent. Keep it up. Thanks a lot.

[@MiledRizk]

Thanks, this was a clear explanation.

[@DotNetHow]

Thanks a lot for your feedback @MiledRizk!

[@Imafriggingoddess]

Nicely explained! However, I've yet to understand how delegates can help me in a real life scenario. I've worked as a c# dev for almost 4 years and I've yet to run into a scenario where I thought "A delegate would be great here". Thanks for the video!

[@DotNetHow]

I just created this blog post which I think would help you better understand Delegates. Check it out and let me know - dotnethow.net/delegates-in-c-sharp-with-examples/

[@Imafriggingoddess]

@@DotNetHow Amazing, thanks!

[@GiSeiNoREI]

​@@DotNetHow I still don't see the usefulness of delegates. One can still call those methods without using the delegate in the multi-casting example. I'll always go for less lines of code. Perhaps an example of code refactoring using delegates would prove their usefulness.

[@DotNetHow]

Delegates can be incredibly useful in certain scenarios, especially when it comes to event handling or implementing callbacks. Keep exploring and you might find a situation where delegates can make your life as a C# dev much easier!

[@zouken2571]

Very helpful, thanks

[@shanmugapriya8562]

You are welcome

[@theprogrammer7837]

u're a great teacher and this is a fact

[@DotNetHow]

Thanks Hicham

[@Bmaster3234]

You explained this well, but I don't understand why someone would want to use a delegate instead of a plain and simple method

[@Twelve.]

Thank you!!

[@Michael-Mosca]

i stopped coding after college for like 4 years and completely forgot delegates existed

[@DotNetHow]

I hope you found this tutorial useful

[@efai]

you can just call ToUpperCase and ToLowerCase methods directly and it will do the same thing.. what's the point here to do this with delegate ? wouldn't be better example, if you would have a second class involved ?

[@DotNetHow]

Sure, I could have used other examples, but that would be an easy to understand method, so I used that.

[@sirishmisthry8462]

6 months of confusion ended by this video

[@DotNetHow]

Glad to hear that 😃

[@DavidCoptil]

nice one, but the music is a bit distracting.

[@DotNetHow]

I agree. I have not used any music in my other tutorials.

[@hassanarabahmadi]

Thank u but if we Add both upper and lower to delegate which one of them will show?😅

[@Lanthiren]

why is the text lowercase in before in the WriteOutput() method, and then uppercase after?

[@lee5150]

No matter how many video I watch on delegates, I don’t not understand them! I can’t even imagine the concept of them. People on a course I’m taking struggled so much with interfaces but I find delegates MUCH more confusing!

[@xanh.9999]

thank you

[@DotNetHow]

you are welcome

[@Ramboo339]

Never seen .Invoke before, how does that work? Most examples I see use callbacks

[@arkanglegeibriel]

note: the "delegate" keyword is never mentioned.

[@Iam_inevitabIe]

Don't get what u mean here chief

[@kiPROBRos]

Excelent.

[@DotNetHow]

Thanks

[@perelium-x]

Is delegate a begginner or intermediate or adv??

[@Cleax21]

Intermediate / advanced.

[@DotNetHow]

Correct

[@MirAnupamHossainAkib--]

thanks

[@DotNetHow]

You're welcome!

[@nimecloud]

At the end I know what delegate is in C#

[@RyantheCanuckpirate]

This is a great video (and maybe it's just me) but the loud music during the video is really distracting. It's competing with your voice for my attention, which I find counterproductive

[@sonnyobrien]

what is a parameter

[@DotNetHow]

A value that gets passed to a method

[@sonnyobrien]

@@DotNetHow what?! But what is a method?

[@alexhawkins5486]

@@sonnyobrien a method is a function

[@sonnyobrien]

@@alexhawkins5486 why not just call it a function?

[@GiSeiNoREI]

You forgot to explain why are delegates useful. In your example they're not. It's just additional code without benefits.

[@regular-user]

Maybe I'm too stupid or these tutorials just don't help. Here is the problem... why use delegates when the function itself could simply be placed in there and it would do the exact same thing? I'd love to see real life examples of when delegates are more useful than not. What you just did there can also be done by just placing the methods in Main, so why use a delegate at all? 🤷‍♂️

[@Dismanameboi]

I think it’s so you can pass a function into a method
