How can i make N label? : Because this isn't work:

            int z = 0;
            for (int k = 0; k <5; k++)
            {
                Label l = new Label();
                l.Name = string.Format("betu{0}", k);
                l.Text = "_";
                l.Height = 75;
                l.Width = 25;
                l.Location = new Point(300 + z, 10);
                this.Controls.Add(l);
                z += 10;
            }
 
This make only 1, and I would like to create more label, right to the last.
