Question

I’m wondering what is the easiest way to persist a string value, once the form and program are shutdown that I want to use again later when they open the program and form later. In my case I’m using a FolderBrowserDialog and saving the directory the user picks.

I know I can use File.IO and such, but just wondering what everyone thinks is the easiest/most efficient/ least lines of code.

Thanks!

Application Settings are nice and easy to use.

1. Right click on your project and select “Properties”
2. Go to the “Settings” tab (Click to link to create a new file if one hasn’t been created)
3. Give your new settings a name and default value (ie “MySavedDirectory”)
4. Access your setting from code:

–

private string folder;
private void Form1_Load(object sender, EventArgs e)
{
  this.folder = Properties.Settings.Default.MySavedDirectory;
}

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
  Properties.Settings.Default.MySavedDirectory = this.folder;
  Properties.Settings.Default.Save();
}
