    The error says the index you are using is out of range for the list. reader.GetInt32 dont have element number 4. please remember that index starts from zero. – Abbas Dehghan Mar 02 '19 at 08:04
  • I rekon `reader` is an SQL query reader, but can you provide more code, so we can see what the `reader` is and where you get it from? – Max Mar 02 '19 at 08:08

You can check 

if(!reader.IsDBNull(4)){
 textBox2.Text = reader.GetInt32(4).ToString();
}
