In addition to Iordan’s answer, if you don’t know exactly where on your form the textbox is, then this extension method should help alot. Note, Form‘s inherit from Control somewhere down the track too, so you can call it from that, or any control on your form.

public static class ExtensionMethods
{
    public static Control FindControl(this Control root, string name)
    {
        foreach (Control c in root.Controls)
        {
            // Check this control
            if (c.Name == name) return c;

            // Check this controls subcontrols
            Control tmp = c.FindControl(name);
            if (tmp != null) return tmp;
        }

        return null;
    }
}

If this still isn’t flexible enough for you, then you can iterate over System.Windows.Forms.Application.OpenForms
