❔ I need to make sure I understand and doing this correctly

I'm learning coding in class and this video explain classes and objects. I tried my best to follow what the instruction want while making sure I understand everything. I only got one error which I think I know where I messed up but I want to make sure everything else is correct.

in the first image technically there isn't a closing }, although it could be outside

Got it.... Also what do you mean? Oh Yeah, it's outside it

@mrw419 You need to override ToString() method in Fruits class

MRW419OP•2y ago

What do you mean?

many things•2y ago

well probably first you need to correct the errors why are errors not underlined in ToString you have "fruit 1: " + Apple; which is not a call nor an assignment, so it's a mistake

i thought that was error, but it can work like this also works this way too

Person person = new Person("David", new DateTime(2001, 09, 21));
string pepsi = $"Person :" + person;
Console.WriteLine(pepsi);

Person person = new Person("David", new DateTime(2001, 09, 21));
string pepsi = $"Person :" + person;
Console.WriteLine(pepsi);

@mrw419 So, every class in C# is sub-class of Object class. object have some methods inside it, like ToString. what inheritance means, everything not private from based class u also have in sub-class. like on thing i painted, so, that means in your Fruits class u have ToString Method (this method is virtual, that means it can be overridden), so, that ToString Method works different way in different environment. as i get, all u need to do, thats override this method in your Fruits class.

public override string ToString()
{
    // code
}

public override string ToString()
{
    // code
}

so that will be behavior of instance of Fruits class when it used like string. i hope i explained it correctly and that was main problem here

and also here, i think we need to call constructor which have 0 arguments

xdd•2y ago

Fruits Apple = new Fruits();

Fruits Apple = new Fruits();

Fruits Apple = new();

Fruits Apple = new();

I'll definitely need to overlook this when I get back to school. Since at this moment I'm out eating.

Some of those I never heard of yet such as override, internal class, {get; }

xdd•2y ago

class Furits = internal class Fruits, almost everything have access modifiers, for classes by default is internal
