how do I make a text file line into a list-CodePudding

is it possible to make this into a list and then make a code where I can delete what's inside the list per line (text file) and then searching the contents of the list

class data
    {
        public void addData(string user_name, string user_email, string user_gender, string user_contact)
        {
            using (StreamWriter writer = new StreamWriter("data.txt", true))
            {
                writer.WriteLine(user_name   " | "   user_email   " | "   user_gender   " | "   user_contact);
            }
        }
    }

CodePudding user response：

It is possible! And Microsoft write some really nice documentation for you to learn about it right here. Here's a simple little program to read the file into a list.

const string file = "{insert your path here}/data.txt";

var stringList = File.ReadLines(file).ToList();

foreach (var line in stringList)
{
    Console.WriteLine(line);
}

There's a nice example on the documentation I've linked that shows you how to lookup things on that list so I'll leave the next part for you to work out
