I'm writing a very simple WP7 app. The it will by kind of notepad. My task is to create an account for user- I'm doing it by saving data in textfile. I don't have any idea how to read logins and passwords from the text file. Of course the best solution will by database but I don't have enough skills to do that.
Here is my code.
Reading and saving:
private void addUserToFile()
{
string fileName = "Logins.txt";
using (var isoStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
using (var isoStream = new IsolatedStorageFileStream(fileName, FileMode.Append, isoStorage))
{
// opens the file and writes to it.
using (var fileStream = new StreamWriter(isoStream))
{
fileStream.WriteLine(typeLogin.Text+"\t"+typePassword.Password);
}
}
NavigationService.Navigate(new Uri("/MainPage.xaml", UriKind.RelativeOrAbsolute));
}
}
And finally reading from textfile ( no idea how to iterate line by line, logins and passwords are separated by TAB):
private void bGoToPage2_Click(object sender, RoutedEventArgs e) //przechodzenie na druga strone
{
if (string.Equals(passwordBox1.Password,passwordBox2.Password))
{
MessageBox.Show("Passwords match!");
if (Login1.Text == "admin") //how change it to reading from file????
{
NavigationService.Navigate(new Uri("/Passwords.xaml?param=" + Login1.Text, UriKind.RelativeOrAbsolute));
}
else
{
MessageBox.Show("Nie znaleziono użytkownika");
}
}
else
{
MessageBox.Show("Passwords do not match!");
NavigationService.Navigate(new Uri("/MainPage.xaml", UriKind.RelativeOrAbsolute));
}
}
If you want to read, simply replace the writer class with reader class.
// opens the file and writes to it.
using (var fileStream = new StreamReader(isoStream))
{
var login = fileStream.ReadLine();
var password = fileStream.ReadLine();
}
You can now write login and password into its own line.
Hope this helps. Although I wouldn't recommend saving user name and password like that in clear text.
