C# getters & setters 🔒

C# getters and setters encapsulation tutorial example explained

#C# #getters #setters

//getters & setters = add security to fields by encapsulation
// They're accessors found within properties

// properties = combine aspects of both fields and methods (share name with a field)
// get accessor = used to return the property value
// set accessor = used to assign a new value
// value keyword = defines the value being assigned by the set (parameter)

using System;

namespace MyFirstProgram
{
class Program
{
static void Main(string[] args)
{
//getters & setters = add security to fields by encapsulation
// They're accessors found within properties

// properties = combine aspects of both fields and methods (share name with a field)
// get accessor = used to return the property value
// set accessor = used to assign a new value
// value keyword = defines the value being assigned by the set (parameter)

Car car = new Car(400);

car.Speed =



Console.ReadKey();
}
}
class Car
{
private int speed;

public Car(int speed)
{
Speed = speed;
}

public int Speed
{
get { return speed; }
set
{
if (value > 500)
{
speed = 500;
}
else
{
speed = value;
}
}
}

}
}

I just read 15 pages over this concept and walked away more confused than before I started. You explain concepts in such a beginner-friendly way and don't include a lot of random unnecessary stuff. I really appreciate you and the content you make. I feel like a lot of programmers have been coding for so long that they forget to slow down a bit when teaching people.

This really helped me understand. It seems like getters and setters can be described as:
Do this when someone GETS the variable.
Do this when someone SETS the variable.

After all these years of coding and never understanding any of this. You helped me understand it within 3 minutes. Thank you!

If anyone else didn't understand at first I'll try to explain my interpretation.
The point of getters/setters is so that we can sort of limit/encapsulate information by having a private field, and we have our property sort of act as a decryption key, I don't really know a good analogy for setters/getters. I think we can make things read only if we private the setter though.

The get accessor is used when we're reading/accessing the value of a property. ie.
The set accessor is used when we're writing/reassigning the value of a property ie. Class.Property = 550;

The value keyword comes from what we input in the constructor. You can only access either set/get at a time as you're either reading/writing, and you can put your own logic/conditonal statements in there like bro did with the if/else statements.

In the write example. when we're instantiating a new car Object, and we input 550 as an argument, we are writing/reassigning.
Car car_1 = new Car(550); Here we're writing, int value of 550 is in the constructor, therefore we're going to use the set accessor. If our value (550) is greater than 500, it sets the speed to max 500, otherwise our speed will just be set to whatever we inputted as long as it's <= 500.

When we then go to access the value of the object we just instantiated, car_1, we are reading/accessing.
So when I type: we are accessing the get accessor which is just returning the value (500) that was set during the initialization in the previous paragraph.

Man, I always had so much diffilcult with this. But you, you bro, you in a 4 minutes video you managed to explain to me masterfully. You're a legend bro. You just got a new subscribe and fan!

[binjozoken]

That was a brilliant way of explaining C# properties. Thanks. I'm sure I'll be back to watch it again.

[Rahulsingh-theraha]

Awesome explanation..I was so confused on its use case...But u made me understand completely ☺️

[FunnySubmarine-ijzk]

Thank youu. It feels like it's the first time to actually understand what getters & setters are and why we use them.

[KZ]

Explaine better than all my teachers combind. thank you for actually letting this make sense.

[stevancosovic]

Thanks bro, very good explanation, this channel deserves more views and support!

[amjadhani]

Wow. I understood getters and setters in only 4 minutes. What a great illustration video. Thanks!

[san_dingus]

Just went through a 2 hour C# course, and it ended right after he showed us classes, fields, and constructors. I don’t think properties and getters/setters were even mentioned.. So, going along with another tutorial, I was very perplexed when he put in { get; set; }. I tried to read the documentation online, but just confused myself even more. Your 4 minute video explained it well enough for me to completely understand it, so thank you!!

[antoinenowakowski]

hello i'm french and we can understand you very well, thanks.

[Slaygee]

Thank you, this was the best explanation I've seen.

[mfnuqef]

Hello Bro Code, your vids are always helpful. Could you perhaps do tutorials on C# lambdas and LINQ I feel like you are the only one that could explain them so I can understand thanks

[noahyannis]

Then why do we use getters and setters in properties if there is no validation/additional code in most setters?

[GothicRK]

Wow I FINALLY understood this. Thank you!!

[Ally-ujdi]

You have no idea how hard I cried: After this tutorial. It all makes sense now! THANK YOU!!! I have been asking ChatGPT to explain me this, and it was failing miserably :')

[diandradeeke]

but if you create a unique getter and setter and only programm that the value is set to the value the function gets or returns the current value, than its not different than without using getters and setters, isnt it?
