Question

I recently moved from Visual Basic 6 to C# 2010 .NET.

In Visual Basic 6 there was an option to put how many control arrays you would like to use by changing the “index” on it.

I am wondering if this is possible in C#, if so how would I go about doing it with a class like:

func fc = new func();

But with more than just one array in fc, is this possible?

And to be more clarified,

Visual Basic 6 when you load a control like a text box or user control it has in the properties window a option for “Index” and if you change that to 0, 1, etc… it’ll allow you to use all of those indexes, without loading multiple controls 50 times.

I think it might have something to do with an arraylist but I’m not entirely sure.

Thanks for any help.

That code snippet isn’t going to get you very far. Creating a control array is no problem, just initialize it in the form constructor. You can then expose it as a property, although that’s generally a bad idea since you don’t want to expose implementation details. Something like this:

public partial class Form1 : Form {
    private TextBox[] textBoxes;

    public Form1() {
        InitializeComponent();
        textBoxes = new TextBox[] { textBox1, textBox2, textBox3 };
    }

    public ICollection<TextBox> TextBoxes {
        get { return textBoxes; }
    }
}

Which then lets you write:

var form = new Form1();
form.TextBoxes[0].Text = "hello";
form.Show();

But don’t, let the form manage its own text boxes.
