Well I would like to Write the info of Textbox1.text into a text file called Settings.txt, and then I want it to load the current Settings.txt into TextBox1 if I Press "Load". I got the Writing to the text file down, but not the reading of the file = textBox1.text.

Here is the whole code:

Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;

namespace TextFileWriter
{
    public partial class Form1 : Form
    {
       
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            TextWriter tw = new StreamWriter("Settings.txt");
            tw.WriteLine(textBox1.Text);
            tw.Close();
           
           
        }

        private void Form1_Load(object sender, EventArgs e)
        {
           
        }

        private void button2_Click(object sender, EventArgs e)
        {
            string Info = textBox1.Text;
            TextReader tr = new StreamReader("Settings.txt");
            Info = tr.ReadLine();
            tr.Close();
        }
    }
}


Button 1 = save
Button 2 = load


Thank you Very Happy

you're never reading anything into the textbox, just the string you create.

Code:
            using (StreamReader sr = new StreamReader(Directory.GetCurrentDirectory() + "\\Settings.txt"))
            {
                String line;
                while ((line = sr.ReadLine()) != null)
                {
                    textBox1.Text += line + Environment.NewLine;
                }
            }
