Can't read from file in same folder

I am trying to select a random line from a txt file in the same folder, it is called "pickupDA.txt" and so I have tried to get the lines from it with File.ReadAllLines("pickupDA.txt"); but it doesnt work. i have tried with "./pickupDA.txt" and "/pickupDA.txt" and ".\pickupDA.txt", none of it works

using MauiAppInformatik.ViewModel;
using System;
using System.IO;

namespace MauiAppInformatik
{
    public partial class MainPage : ContentPage
    {
        private string PLOTD()
        {
            string[] lines = File.ReadAllLines("pickupDA.txt"); // FIX PATH 

            int seed = DateTime.Now.DayOfYear;

            Random random = new Random(seed);
            int randomIndex = random.Next(0, lines.Length);

            string selectedLine = lines[randomIndex];

            return selectedLine;
        }

        // More code here

That code tries to read from the user's current working directory. By default, that's the folder which contains your application's .exe file, but the user can change that But, if your pickupDA.txt is next to your .cs files, then it won't be next to your .exe

so i should reference the txt file from the "perspective" of the exe? where is that exe located in maui? google isnt helping

If the text file is part of the project, just set up a copy of newer action on the item Can be done in the properties in the solution explorer

I would add a line to print the path of the executable, then run it Like so "Console.WriteLine(System.IO.Path.GetDirectoryName(Application.ExecutablePath));" Then I would change the path to go back as many directories as your text file is in like "../../../pickupDA.txt" Or just put the text file in the same printed path
