C# DELEGATES in 8 minutes! Learn .NET FAST!

We'll make sure to make a Developer out of you in no time!
So, what is C#?
C# (pronounced "See Sharp") is a modern, object-oriented, and type-safe programming language. C# enables developers to build many types of secure and robust applications that run in .NET. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers. This tour provides an overview of the major components of the language in C# 8 and earlier. If you want to explore the language through interactive examples, try the introduction to C# tutorials.
And what are DELEGATES in C#?
A delegate is a type that represents references to methods with a particular parameter list and return type. When you instantiate a delegate, you can associate its instance with any method with a compatible signature and return type. You can invoke (or call) the method through the delegate instance.
Delegates are used to pass methods as arguments to other methods. Event handlers are nothing more than methods that are invoked through delegates. You create a custom method, and a class such as a windows control can call your method when a certain event occurs.
Any method from any accessible class or struct that matches the delegate type can be assigned to the delegate. The method can be either static or an instance method. This flexibility means you can programmatically change method calls, or plug new code into existing classes.

[@vagifk2864]

Explained how it works, but not why and where ! Minus !

[@zzz-ovidiu2015]

[@yumyum7196]

Yea, which is key to understanding

[@TheSeriousDog]

Why: To try to impress other developers Where: Any place you want to make it more complicated

[@rainrope5069]

Use them for callbacks.

[@KillAllCommies2]

@@TheSeriousDog Take this with a grain of salt because I am a total noob. But from what I understand, delegates are a way to save processing with events, since these require delegates and are only processed when they are required. This seems to be important in contexts that requires a lot of processing optimization (example: video games)

[@SaveTheHedgehog]

I like functional :) (specifically is the C# language, not F#)

[@Ayman73795]

i like functional programming

[@kailuu8185]

Was going to buy your stuff….. but not now. You literally taught so little in this video and used the most pointless example.

[@davidmuradyan4014]

But it was good for introduction. It was just 8 minutes)

[@trzztrzz2477]

Yeah but what is the practical use? Is it really useful? I don't understand man. Why should I use this thing? Damn I wanna give this shit up.

[@ernest1428]

Hey do you know what this is for? I am stuck since 6 hours trying to understand this shit in order to understand events hahaha

[@LaughingMan44]

don't worry, you have mid-level programmers like this who are able to tell you what something is, but not why something is useful.

[@ahmedbahnasy2243]

Thanks for the simplicity !

[@ezecel9]

Do you think that sending a delegate into a entity method (following DDD) is a good practice? For example, if that delegate is a database request to get another entity that the first entity needs? Or we have to call it before? Thanks!

[@tutorialsEUC]

Hi, No, that's not a good practice. Preferably entities should not access data directly or indirectly. Entities encapsulate business logic and they must not depend on lower-level stuff like database access :-) Good question!

[@ezecel9]

@@tutorialsEUC thanks!

[@cristiancristinel2562]

I have a question, as I am interested in the course, but I cannot attend it at the same time for 21 days. So, is it possible to buy just the acces to its videos ? Do you have more in-depth videos about all this subjects that can be purchased ?

[@bluemodize7718]

I like how you compare it to js because I have a lot of experience in js

[@elijahgundorin1189]

So true.. the reference to js was a lightbulb moment for me.. somehow seems much simpler to think of it as simply the c# version of a js callback

[@tsmale316]

​@@elijahgundorin1189exact same for me!

[@abiofficial-ws7pn]

@bluemodize... Not sure if you're sarcastic or serious. That sentence referring to javascript is a double-edged sword since it'll make people unfamiliar with js think that they are poorly placed to understand delegates in C#

[@_yllw6155]

functional programming in an oop languange

[@ngocthuytran3114]

I would like to learn more about Functional Programming!

[@heshammostafa3446]

I like functional

[@iswilson]

You never run the code?

[@KillAllCommies2]

I didn't get it :V

[@rushas]

The explanation could have been simpler and easier to understand. Note that "simpler" does not mean less lines of code

[@EMdragonKnight]

Good video.

[@mohamedassekour2992]

there is a big difference between Explaining concept and Explaining a its syntax. you explained the syntax not the concept you waste my 8 min in nothing

[@sahild6584]

Handsome man

[@bojohannesen4352]

Simp

[@GiSeiNoREI]

That's an awful explanation of delegates.

[@zzz-ovidiu2015]

fr

[@bojohannesen4352]

What's up with the dumb thumbnails. I am so happy that they haven't worked out for you.

[@LaughingMan44]

at no point did you demonstrate why this is remotely useful, when I can just call the methods inside another method without having to pass them as arguments

[@kvelez]

PrintDelegate Display = Console.WriteLine; PrintDelegate Printer = (string text) => Console.WriteLine(text); PrintDelegate PrintToFile = (string text) => { File.AppendAllText("C:/Users/kvele/Downloads/logs.txt", text); }; void DbContext(PrintDelegate log) { log("DELETE FROM users"); log("SELECT * FROM users"); }; Display("Hello World"); Printer("Hello World"); PrintToFile("Hello World"); DbContext(Display); delegate void PrintDelegate(string text);

[@WolfgangMZwing]

not needed, interfaces do same job

A shame that this tutorial is DYSfunctional
