would you be using stream reader? could i see an example of this?

Are you reading all the lines, or just some? If reading all, I'd probably use string[] lines = File.ReadAllLines(...)

i want to read one line at a time so first read the first line, check for a value, then move onto the second, check for another value that i need etc and so on

var reader = File.OpenText("text.txt");

var x = reader.ReadLine();
Console.WriteLine(x);

var y = reader.ReadLine();
Console.WriteLine(y);

var reader = File.OpenText("text.txt");

var x = reader.ReadLine();
Console.WriteLine(x);

var y = reader.ReadLine();
Console.WriteLine(y);

ooo i see so this reads each line individually?

Pobiega•11mo ago

each time you call ReadLine() it reads one line and returns it
