How to print out specific value of an array in .txt file?

See more:

So i got a task which has 2 .txt files for me to use. I have to find the biggest value in each of those txt files and then after compare those values and print out the biggest out of all of them(if the biggest values are the same in both text files it should print out those values). Here are the text values(the name and parts of the code are in lithuanian.):

Note.The values are at the end of each line for example(

ORION; 2; 1935; 365,1;

) the value is 365,1
So this is "A.txt"

ORION; 2; 1935; 365,1;
POLARIS; 1; 1988; 87,09;
INDUSTRIERAD; 10; 1995; 58,10;
Bauer; 25; 2008; 1040,42;
HERREN; 15; 2012; 1040,42;

And here is "B.txt"

            }
            return ret;
        }
    }
}

So i find the biggest values, but the problem is i don't know how to print out the rest. It only takes the first value and prints it out to other values. Idk how to explain it.

kaina = the value;

What I have tried:

I need ~~fast~~ help with the code

Hi member,

Sorry but I won't read that code - Looks horrible to me (btw. why not write code always in english? I speak german, but my code is english and so is the framework..) - And did you port that from C? Maybe use some of the Framework Methods or LINQ?

Anyway I can show you an example how I would aproach this. Maybe you can find something useful: I created an Console-App you can run. - just create a new console application in visual studio and replace Program.cs with the following (and adjust the filepaths)

C#

using System;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;

namespace Compare
{
    class Program
    {
        static void Main(string[] args)
        {
            // read values from both files
            List<double> listValuesFileA = ProcessFile("TextFileA.txt");
            List<double> listValuesFileB = ProcessFile("TextFileB.txt");

            // get max value from files
            double dMaxFileA = listValuesFileA.Max();
            double dMaxFileB = listValuesFileB.Max();

            // ... and write them to the console            
            Console.WriteLine($"Max Value File A: {dMaxFileA}");
            Console.WriteLine($"Max Value File B: {dMaxFileB}");

            Console.ReadKey(true);
        }

        // reads the values from the file and returns a list of all values
        static List<double> ProcessFile(string strFilePath)
        {
            List<double> listResults = new List<double>();

            // read the file
            string[] astrLines = File.ReadAllLines(strFilePath);

            // find the values by looping through all lines
            foreach (string strLine in astrLines)
            {
                string[] astParts = strLine.Split(";".ToArray(), StringSplitOptions.RemoveEmptyEntries); // ';' is the separator-sign
                // check if we got one of the lines with the values (always 4 values in such lines)
                if (astParts.Length == 4)
                {
                    // only consider the last values of each line
                    string strLastValue = astParts.Last();
                    // convert the value considering culture!
                    if (double.TryParse(
                        strLastValue,
                        System.Globalization.NumberStyles.Any,
                        System.Globalization.CultureInfo.CreateSpecificCulture("lt-LT"), // Lithuanian culture
                        out double dResult))
                    {
                        listResults.Add(dResult);
                    };
                }
            }

            return listResults;
        }
    }
}

Feel free to ask if you have any questions?

kind regards Johannes
