I am new to C#. This is my code. When I run this code, I input the car name, mileage, year, make, model, color, and bodytype to a list that looks like this
* Name of Car: Car 1
Enter Mileage: 4000 (my input)
Enter year: 2022 (my input)
Enter make: ford (my input, etc.)
Enter model: fusion
Enter color: red
Enter bodytype: coupe
Name of Car: Car 2
Enter Mileage: 4000
Enter year: 2022
Enter make: ford
Enter model: fusion
Enter color: red
Enter bodytype: coupe
Name of Car: Car 3
Enter Mileage: 4000
Enter year: 2022
Enter make: ford
Enter model: fusion
Enter color: red
Enter bodytype: coupe*
and I want to return what I input for car 1, car 2, car 3 as three side by side arrays with commas looking like this?
*car 1, 4000, 2022, ford, fusion, red, coupe
car 2, 4000, 2022, ford, fusion, red, coupe
car 3, 4000, 2022, ford, fusion, red coupe*
Below is what I wrote for code, at the very end of this code is where I want to print the side by side arrays. Applying concepts of objects and methods, what should I write in order print that side by side array on the console window?
using System;
using System.Management.Instrumentation;
using Assignment5;
namespace Assignment5
{
public class Car
{
//public:
public void Set_Name_of_Car(string name)
{
name_of_car = name;
}
public void Set_Body_Type(string Type) //methods that you can call
{
bodytype = Type;
}
public void Set_Make(string Color, string Make, string Model )
{
color = Color;
make = Make;
model = Model;
}
public void Set_Mileage(int Mileage, int Year)
{
mileage = Mileage;
year = Year;
}
public void Show()
{
Console.WriteLine();
Console.WriteLine();
Console.WriteLine();
}
}
}
namespace Program
{
internal class Program
{
static void Main(string[] args)
{
Car car1 = carInfo();
Car car2 = carInfo();
Car car3 = carInfo();
}
public static Car carInfo()
{
Console.WriteLine("Enter Name of Car: ");
string n_Aim = Console.ReadLine();
Console.WriteLine("Enter Mileage:");
int miles = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Enter Year:");
int yr = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Enter Make:");
string meigh_k = Console.ReadLine();
Console.WriteLine("Enter Model:");
string mod_L = Console.ReadLine();
Console.WriteLine("Enter Color:");
string Col_R = Console.ReadLine();
Console.WriteLine("Enter Bodytype: ");
string Bdy_Typ = Console.ReadLine();
Car inputcar = new Car();
inputcar.Set_Name_of_Car(n_Aim);
inputcar.Set_Mileage(miles, yr);
inputcar.Set_Make(Col_R, meigh_k, mod_L);
inputcar.Set_Body_Type(Bdy_Typ);
return inputcar;
}
}
}
What I want to try is using but I don't think my instructor wants us to use that method because it's too simplistic. Do you have any other suggestions please? and thank you :D
Console.WriteLine("car 1, 4000, 2022, ford, fusion, red, coupe");
Console.WriteLine("car 2, 4000, 2022, ford, fusion, red, coupe");
Console.WriteLine("car 3, 4000, 2022, ford, fusion, red coupe");

override the tostring function for said class
namespace Assignment5
{
public class Car
{
//public:
public void Set_Name_of_Car(string name)
{
name_of_car = name;
}
public void Set_Body_Type(string Type) //methods that you can call
{
bodytype = Type;
}
public void Set_Make(string Color, string Make, string Model )
{
color = Color;
make = Make;
model = Model;
}
public void Set_Mileage(int Mileage, int Year)
{
mileage = Mileage;
year = Year;
}
public void Show()
{
Console.WriteLine();
Console.WriteLine();
Console.WriteLine();
}
public override string ToString()
{
return name_of_car ", " mileage ", " year ", " make ", " model ", " color ", " bodytype
}
}
}
then just print the string for each car
static void Main(string[] args)
{
Car car1 = carInfo();
Car car2 = carInfo();
Car car3 = carInfo();
Console.WriteLine(car1.ToString());
Console.WriteLine(car2.ToString());
Console.WriteLine(car3.ToString());
}
you can also do this as it will automatically call the ToString method
static void Main(string[] args)
{
Car car1 = carInfo();
Car car2 = carInfo();
Car car3 = carInfo();
Console.WriteLine(car1);
Console.WriteLine(car2);
Console.WriteLine(car3);
}

You can override the ToString method of Car that every class inherits from object to let a car display itself. In the car class, add this method:
public override string ToString()
{
return $"{name_of_car}, {mileage}, {year}, {make}, {model}, {color}, {bodytype}";
}
You also better add the cars to a list. This simplifies the handling of cars, as you can easily process any number of cars now, without having to add more car variables.
var cars = new List<Car>();
cars.Add(carInfo());
cars.Add(carInfo());
cars.Add(carInfo());
foreach (Car car in cars) {
Console.WriteLine(car);
}
Note that Console.WriteLine automatically uses the ToString method to display any objects.
The Show method in Car is no more required. Input/output (Console.ReadLine/WriteLine) should be done in a data class.
You could also have the user input cars until he presses Enter without entering a name. To do this return null from the input method:
public static Car carInfo()
{
Console.WriteLine("Enter Name of Car: ");
string n_Aim = Console.ReadLine();
if (n_Aim = "") {
return null;
}
Console.WriteLine("Enter Mileage:");
...
}
and then
var cars = new List<Car>();
while (true) {
Car car = carInfo();
if (car == null) {
break; // Exit the loop
}
cars.Add(carInfo());
}
foreach (Car car in cars) {
Console.WriteLine(car);
}
