For example, i got a .txt file in which there are cars names, amount of each car, year they were made and their price:

5
ORION; 2; 1935; 365.1;
POLARIS; 1; 1988; 87.09;
INDUSTRIERAD; 10; 1995; 58.10;
Bauer; 25; 2008; 285.58;
HERREN; 15; 2012; 1040.42;

I find the max value with for cycle that is 1040.42. So next i need to find the max values name(Herren), the amount of of that car that there is and the year it was made.
So the problem is i don't know how to find all of this. I need to use "for" and "if", but havo no idea how to do it.

What I have tried:

Everything that is on the internet.

First create a POCO that represents according to your data:

C#

public class Car
{
	public string Name { get;set;}
	public int Amount { get;set;}
	public int Year { get;set;}
	public decimal Price { get;set;}
	
	public override String ToString()
	{
		return String.Format("Name:{0},Amount{1},Year:{2},Price:{3}",Name,Amount,Year,Price);
	}
}

and then read the file and then create a collection and then use linq to get the car with highest price and print it out:

C#

var lines = File.ReadAllLines("cars.text");

int totalCars = Convert.ToInt32(lines[0]);
		List<Car> cars = new List<Car>();
		for(int i = 1; i < totalCars; i++)
		{
			var line = lines[i];
			var carInfo = line.Split(';');
			
			Car car = new Car();
			car.Name = carInfo[0];
			car.Amount = Convert.ToInt32(carInfo[1]);
			car.Year = Convert.ToInt32(carInfo[2]);
			car.Price = Convert.ToDecimal(carInfo[3]);
			
			cars.Add(car);
		}
		
		var carWithHighestPrice = cars.OrderByDescending(x=>x.Price).First();
		
		Console.WriteLine(carWithHighestPrice);
