Didn't you ask about it before, and were advised to just use proper classes instead of lists of properties? Indeed, #✅ write multiple Lists to file Something doesn't work still?

Sam DZOP•2y ago

@Angius Sorry but i didn't know how to do it

MODiX•2y ago

TheRanger#3357

something like

public class Ship
{
   public string Name {get;set;}
   public decimal Price {get;set;}
   public int Quantity {get;set;}

   public string Address {get;set;}
   public string ShippingType {get;set;}
   public string PayType {get;set;}
}

public class Ship
{
   public string Name {get;set;}
   public decimal Price {get;set;}
   public int Quantity {get;set;}

   public string Address {get;set;}
   public string ShippingType {get;set;}
   public string PayType {get;set;}
}

and in ur class Shipping

class Shipping
{
   public static List<Ship> Ships = new List<Ship>();
}

class Shipping
{
   public static List<Ship> Ships = new List<Ship>();
}

@Angius I don't know how to use getters and setters to do it I need fully explained code for it with getters and setters

Angius•2y ago

You don't use them, not directly

var s = new Ship();
s.Name = "Carrots"; // this uses the setter
var n = s.Name; // this uses the getter

var s = new Ship();
s.Name = "Carrots"; // this uses the setter
var n = s.Name; // this uses the getter

So how to copy list items to this?

Firehawk•2y ago

There's plenty of ways you can go about serializing that data - could do it csv-style, or even json depends on your needs

Sam DZOP•2y ago

I'm literally a beginner and this is my first oop so i don't know how to do it unfortunately and Googled it a lot and didn't find what i want

Angius•2y ago

var ships = new List<Ship>(){
    new Ship {
        Name = "Carrots",
        Price = 12.9,
        Quantity = 89,
        Address = "18 Boulevard Avenue, Boroughshire",
        ShippingType = "Super Ultra Express",
        PayType = "Bags of rye"
    },
    new Ship {
        Name = "Carrots",
        Price = 12.9,
        Quantity = 89,
        Address = "18 Boulevard Avenue, Boroughshire",
        ShippingType = "Super Ultra Express",
        PayType = "Bags of rye"
    },
};

var ships = new List<Ship>(){
    new Ship {
        Name = "Carrots",
        Price = 12.9,
        Quantity = 89,
        Address = "18 Boulevard Avenue, Boroughshire",
        ShippingType = "Super Ultra Express",
        PayType = "Bags of rye"
    },
    new Ship {
        Name = "Carrots",
        Price = 12.9,
        Quantity = 89,
        Address = "18 Boulevard Avenue, Boroughshire",
        ShippingType = "Super Ultra Express",
        PayType = "Bags of rye"
    },
};

This is how you make a list of those classes If you need to add one outside of the initialization,

ships.Add(new Ship {
        Name = "Carrots",
        Price = 12.9,
        Quantity = 89,
        Address = "18 Boulevard Avenue, Boroughshire",
        ShippingType = "Super Ultra Express",
        PayType = "Bags of rye"
    });

ships.Add(new Ship {
        Name = "Carrots",
        Price = 12.9,
        Quantity = 89,
        Address = "18 Boulevard Avenue, Boroughshire",
        ShippingType = "Super Ultra Express",
        PayType = "Bags of rye"
    });

And saving it to a file could not be easier

var json = JsonSerializer.Serialize(ships);
File.WriteAllText("my-data.json", json);

var json = JsonSerializer.Serialize(ships);
File.WriteAllText("my-data.json", json);

Sam DZOP•2y ago

Oh my god I going to jump from the mountain Thank you a lot ❤️ @Angius What do you think about save each list separately and then combine the files in one?

Angius•2y ago

Makes no sense

Sam DZOP•2y ago

It's called junior solutions hahahah

Angius•2y ago

Do you keep track of your phone contacts with

names = [ "bob", "anna", "joel" ]
numbers = [ 12343245, 4567567, 4564564 ]

names = [ "bob", "anna", "joel" ]
numbers = [ 12343245, 4567567, 4564564 ]

people = [
    { name: "bob", number: 12343245 },
    { name: "anna", number: 4567567 },
    { name: "joel", number: 4564564 }
]

people = [
    { name: "bob", number: 12343245 },
    { name: "anna", number: 4567567 },
    { name: "joel", number: 4564564 }
]

Sam DZOP•2y ago

Of course second one

Angius•2y ago

Exactly

Sam DZOP•2y ago

But the deadline tomorrow and i don't understand the first way Literally I'm going to cry

Angius•2y ago

Whelp, happens I guess you can turn your weird bunch of lists into a list of objects

var ships = new List<Ship>();

for (var i = 0; i < someList.Length, i++)
{
    ships.Add(new Ship {
        Name = namesList[i],
        Price = pricesList[i],
        Quantity = quentitiesList[i],
        // etc...
    });    
}

var ships = new List<Ship>();

for (var i = 0; i < someList.Length, i++)
{
    ships.Add(new Ship {
        Name = namesList[i],
        Price = pricesList[i],
        Quantity = quentitiesList[i],
        // etc...
    });    
}

Sam DZOP•2y ago

Ok And save this final one to text file instead of bunch of Lists

Angius•2y ago

Sam DZOP•2y ago

I have an Idea if it possible instead of edit all code can i copy the bunch of Lists to this one ? @Angius

Angius•2y ago

Yes, I even showed you how

Sam DZOP•2y ago

What is the namespace for saving to text command @Angius I found it ! Put how i will put the path ?

MODiX•2y ago

Angius#1586

var json = JsonSerializer.Serialize(ships);
File.WriteAllText("my-data.json", json);

var json = JsonSerializer.Serialize(ships);
File.WriteAllText("my-data.json", json);
