❔ Reading data from a text file
I have only just started trying to work with txt files and was wondering if anyone could help me and try to fix my code!
string fileName = "Cookies.txt";
TextWriter textFileWrite = new StreamWriter(fileName);
TextReader textFileRead = new StreamReader(fileName);
string data;
if ((data = textFileRead.ReadLine().Skip(1).Take(1).First().ToString()) == null)
{
Console.WriteLine("Would you like to save 'dark' or 'light' theme..."); string choice = Console.ReadLine();
textFileWrite.WriteLine(choice);
}
if ((data = textFileRead.ReadLine().Skip(1).Take(1).First().ToString()) != null)
{
Console.WriteLine("You selected: " + data);
Console.WriteLine("Would you like to save 'dark' or 'light' theme..."); string choice = Console.ReadLine();
textFileWrite.WriteLine(choice);
}
textFileRead.Close();
textFileWrite.Close();

what exactly are you trying to do
its a school assignment im basically trying to write settings to a txt file and then output them if they are present but if there isnt already a saved setting you can set one
since this is a school assignment i won't do much but,
first
you need to check if the file path exists
second if the file exists read inside and check if inside is null (you probably did that)
third if the file does not exists, create one
fourth write to the file, but you still need to check if the user's input is other than you want (other than dark or light)
your code would work goodly if it is inputted correctly
and don't forget to take the latest text that user has put inside your file
if you don't you'll get all of the data inside that fileit's better to make an abstraction in form of a class for the settings, and then a method that read them all from a file and a method that writes them all back.
then you wouldn't have that cryptic code, and you can use a well known format like json or xml or yaml to bring some more order
storing key value pairs in a custom format is also fine tho
