Should I call SqlDataReader.HasRows if I am calling SqlReader.Read

Question

Trying to see if it is beneficial to add an if (dr.HasRows) before the while (dr.read()) function. I mean, technically if it doesn\'t have rows it

Answer 1

It's not mandatory to check if the DataReader has rows (dr.HasRows). The Read() method will return true if there is more data to read and false if there's no more data, thus breaking the while-loop.
