        static void Main(string[] args)
        {
            string firstname;
            string myoutline;
            Console.Write(""); // whatever type here
            firstname = Convert.ToString(Console.ReadLine());
            string path = @"file.txt";
            myoutline = firstname;

            if (!File.Exists(path))
            {
                using (StreamWriter sw = File.CreateText(path))
                {
                    sw.WriteLine(myoutline);

                }
            }
            Console.ReadKey();

If I understand correctly, you want to continually write input to a file. You need a while loop where you check some value condition, like "exit", for example. I also think you want to append to a file, not create a new one for each line read, so that is what I have demonstrated:

    static void Main(string[] args)
    {
        string input;
        Console.Write(""); // whatever type here
        input = Console.ReadLine();
        string path = @"file.txt";

        using (StreamWriter sw = new StreamWriter(path, true))
        {
            while (input != "exit")
            {
                sw.Write(input);
                input = Console.ReadLine();
            }
        }
    }

Thank You. This code is really helpful. But how could i write line by line to the text file that like most write in console form? — cg thanes, Aug 10 '15 at 00:31
@cgthanes add a new line character: `sw.Write(input + Environment.NewLine);` — Crowcoder, Aug 10 '15 at 01:11
