Passwords in C#

Question

Can anyone show me how to get, store and read usenames and passwords inputted by a user? Thanks

I have tried it myself. I can get the user input and write it to a file. The problem occurs when I try to read the passwords back to authorize them. I tested it with to user names and passwords. If you put in a matching username and password, it works...but it also works if you put in an existing username and password. I came up with the code myself. so I know it's not the correct way to do it. Heres my code: This is from one form that asks for the username and password and then writes it to a file: private void button1_Click(object sender, EventArgs e) { string username = textBox1.Text; string password = textBox2.Text; WriteUserAndPassword(username, password); } private void WriteUserAndPassword(string user, string pass) { using (StreamWriter writer = File.AppendText("C:\pass.txt")) { writer.WriteLine("username:"); writer.WriteLine(user); writer.WriteLine("password:"); writer.WriteLine(pass); writer.Dispose(); writer.Close(); } } This code is for the form that asks the user to login: private void button1_Click(object sender, EventArgs e) { using (StreamReader reader = new StreamReader("C:\pass.txt")) { string username = null; string password = null; string content = null; while (reader.ReadLine() != null) { content = reader.ReadLine(); if (textBox1.Text == content) { username = content; } reader.ReadLine(); content = reader.ReadLine(); if (textBox2.Text == content) { password = content; } if ((textBox1.Text == username) && (textBox2.Text == password)) { this.Hide(); Form2 frm = new Form2(); frm.Show(); } } if ((textBox1.Text != username)||(textBox2.Text != password)) { MessageBox.Show("Username or password is incorrect"); } } } private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e) { Form3 frm3 = new Form3(); frm3.Show(); } } I realize the code is very sloppy. I had a hard time finding good tutorials for this. Any help will be appreciated.
