Question

This is my code.
But all my textboxes’s value is just null.

    public void createTxtTeamNames()
    {
        TextBox[] txtTeamNames = new TextBox[teams];
        int i = 0;
        foreach (TextBox txt in txtTeamNames)
        {
            string name = "TeamNumber" + i.ToString();
            txt.Name = name;
            txt.Text = name;
            txt.Location = new Point(172, 32 + (i * 28));
            txt.Visible = true;
            i++;
        }
    }

Thanks for the help.

The array creation call just initializes the elements to null. You need to individually create them.

TextBox[] txtTeamNames = new TextBox[teams];
for (int i = 0; i < txtTeamNames.Length; i++) {
  var txt = new TextBox();
  txtTeamNames[i] = txt;
  txt.Name = name;
  txt.Text = name;
  txt.Location = new Point(172, 32 + (i * 28));
  txt.Visible = true;
}

Note: As several people have pointed out in order for this code to be meaningful you will need to add each TextBox to a parent Control. eg this.Controls.Add(txt).
