Out of range error on SqlDataReader

Question

I\'m using a SqlDataReader and get this exception when trying to read a column...

System.IndexOutOfRangeException: record

Answer 1

That's because you have no field named "record", you aliased it to "CUSTOMER_NO" so change the code to:

lblWebMasterMessage.Text += "record " + reader["CUSTOMER_NO"].ToString() + "
";

That said, you can also use index instead of name so to read the second column:

lblWebMasterMessage.Text += "record " + reader[1] + "
";
