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?

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

SDSam DZ

@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

AAngius

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?

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

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);

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?

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 }
]

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...
    });    
}
