Question

This is the code:

private void button1_Click(object sender, EventArgs e)
    {
        List<string> user = new List<string>();

        user.Add(usertextBox.Text);

I want it where each time I press the button, whatever is in usertextBox at that point gets added to the list ‘user’ as a new item, so I can recall the different ones later with [1], [2], [3], etc. I also want it so the user can close the app and all the users will still be saved. I I don’t know if C# does this automatically

Even if you can only answer one of my questions that’s fine. Thanks!!

Answer 1

In your code you are making List local to Button that means every time you click button new object of List is created, You should create it out side button click method. Try this.

List<string> user = new List<string>();
private void button1_Click(object sender, EventArgs e)
    {
        user.Add(usertextBox.Text);
