Answer 1

It looks like you’re trying to create fields inside a constructor. You can’t do that, do something like this instead:

private TextBox[] TextBoxes = {textBox1, textBox2, textBox3, textBox4, textBox5, textBox6};

private List<string> storeItems = new List<string>();

public Form1()
{
    InitializeComponent();
}

And it also looks like you have the capitalization wrong. TextBoxes is different from textBoxes in C#.
