How do i save the contents of a textbox after session end

Question

So I am new to c# and WinForms and I am trying to save the contents of a textbox, all of the things I saw online were completely useless and to complete my project i need to be able to save the contents of a textbox between sessions.

Here is my code:

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

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

        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                string link1 = textBox1.Text;
                Process.Start("chrome", @link1);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message.ToString());
            }
        }
    }
}

Sorry is this is messy any answer is appreciated!

Answer 1

Does it need to be to a file?

You could create a string Setting in the application and save/access it when you like.

Accessing a setting.

textBox1.Text = Zero_Light_Fullstack.Properties.Settings.Default.LastText;

Updating a setting.

Zero_Light_Fullstack.Properties.Settings.Default.LastText = textBox1.Text;
Zero_Light_Fullstack.Properties.Settings.Default.Save();
