@It's_Sam

List<string> Data1 = new List<string>();
List<string> Data2 = new List<string>();

public void WriteLists(List<string>[] lists)
{
    int index = 7; // some random index
    foreach(List<string> data in lists)
    {
        if(data.Count >= index)
        {
            // write data to file
            data[index];
         }
    }
}

List<string> Data1 = new List<string>();
List<string> Data2 = new List<string>();

public void WriteLists(List<string>[] lists)
{
    int index = 7; // some random index
    foreach(List<string> data in lists)
    {
        if(data.Count >= index)
        {
            // write data to file
            data[index];
         }
    }
}

is this what you're wanting?

@TheRanger The value inside the List have same index

Angius•2y ago

Why does the index matter...?

boom•2y ago

do both lists have equal length in elements in relation to the specific index??

Angius•2y ago

Write all lines from one list Write all lines from the second list Done

Sam DZOP•2y ago

@driveby no they don't have same length

boom•2y ago

and you're wanting index N from both lists written to a file?

Sam DZOP•2y ago

It's a project for college And I'm storing infos in lists

boom•2y ago

you want all those in 1 file? just do what he said

Angius•2y ago

Ah I see the issue... I think

Sam DZOP•2y ago

Yes in 1 file

Angius•2y ago

Instead of having a list of objects, you have multiple lists storing properties

TheRanger•2y ago

why not make a class called Ship with properties Name, Price , etc....

Angius•2y ago

Instead of a list of people, each of which has a name and age, you have a list of names and list of ages That's not the way to go about it whatsoever

boom•2y ago

ohhhhhhhh i see what he needs

List<dynamic> Data1 = new List<dynamic>();
List<dynamic> Data2 = new List<dynamic>();

// using dynamic just bc i dont know datatypes
public void WriteLists(List<dynamic>[] lists)
{
    int index = 0;
    foreach(List<dynamic> data in lists)
    {
        WriteText(data[index]);
    }
    WriteText("\r\n");
}

List<dynamic> Data1 = new List<dynamic>();
List<dynamic> Data2 = new List<dynamic>();

// using dynamic just bc i dont know datatypes
public void WriteLists(List<dynamic>[] lists)
{
    int index = 0;
    foreach(List<dynamic> data in lists)
    {
        WriteText(data[index]);
    }
    WriteText("\r\n");
}

like this? i havent tested but something similiar?

Angius•2y ago

dynamic

TheRanger•2y ago

dont ever use dynamic, ever

Angius•2y ago

Jesus

boom•2y ago

u can see the comment

Angius•2y ago

You made it worse

boom•2y ago

stop being weird

TheRanger•2y ago

yes i can see the comment

Angius•2y ago

Using dynamic is what's weird

TheRanger•2y ago

ur point?

Angius•2y ago

Just make up some random Order class or whatever

Sam DZOP•2y ago

I'm wondering what would be right A little Joyner asking lol

Angius•2y ago

Using dynamic even as an example tells people it's fine to use it It's not fine to use it A class that describes your objects

boom•2y ago

well, at this rate, they're just criticizing stupid shit, hopefully they'll help you pce

TheRanger•2y ago

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>();
}

Sam DZOP•2y ago

This the final class where show to user what he put in the cart You can say it's just using Console.writeline after showing it in Console app I want to save it in file to desktop

Angius•2y ago

Structure your data properly and writing it to a file won't be an issue

boom•2y ago

lol how are you an associate with that kinda attitude 😂

Angius•2y ago

Sam DZOP•2y ago

@TheRanger I will shook you I tried a lot to know how to use properties and Didn't get it 💔

Angius•2y ago

"How do I eat soup with a fork"? "You shouldn't, use a spoon instead" "lol how are you an associate with that kinda attitude 😂" Whatever, issue seems to be solved That's what matters

Sam DZOP•2y ago

Can u guys recommended to me a video or doc for properties plz 🥹😂

TheRanger•2y ago

MODiX•2y ago

Written interactive course https://learn.microsoft.com/en-us/users/dotnet/collections/yz26f8y64n7k07 Videos https://dotnet.microsoft.com/learn/videos

TheRanger•2y ago

if you want to only see a video for properties specifically, it should be somewhere in the videos link but in general, you should learn all of the fundamentals of C#

Sam DZOP•2y ago

@TheRanger I write about 700 line For this project Bot oop it's kinda new to me so iam facing some issues

TheRanger•2y ago

take your time

Angius•2y ago

OOP is the base of C# It's honestly impressive you managed to write something this big without OOP, only got stuck on saving data to a file

Sam DZOP•2y ago

Nooo It have 9 classes It's fully oop @Angius

Angius•2y ago

Ah, gotcha I thought it's all written with parallel lists of properties lol

Sam DZOP•2y ago

But this is the first time i made an oop console app @Angius Can i talk to u in dm to ask for several things?
