I'm using an SqlDataReader method to run a stored procedure. I get no compile errors if I don't use a catch statement, but I also don't get any data. I've tried doing a console.writeline which doesnt work (guess you can't write to the console when using ASP with classes?). Using this:

try {

 myConnection.Open();
            SqlDataReader result = myCommand.ExecuteReader(CommandBehavior.CloseConnection);

            // Return the datareader result
            return result;
            }

            catch (SqlException e) {
                    Console.WriteLine(e.Message + "\n");
                    Console.WriteLine(e.StackTrace);            
            }
Gives me the error: Not all code paths return a value. How can I return the exception object using a datareader? Thanks! Here's the entire metod:


public SqlDataReader gettheitems(string variety) {


        SqlConnection myConnection = new SqlConnection(ConfigurationSettings.AppSettings["ConnectionString"]);
            SqlCommand myCommand = new SqlCommand("gettheitems", myConnection);

            // Mark the Command as a SPROC
            myCommand.CommandType = CommandType.StoredProcedure;

            SqlParameter parametervariety = new SqlParameter("@variety", SqlDbType.NVarChar, 50);
            parametervariety.Value = variety;
            myCommand.Parameters.Add(parametervariety);
try {

 myConnection.Open();
            SqlDataReader result = myCommand.ExecuteReader(CommandBehavior.CloseConnection);

            // Return the datareader result
            return result;
            }

            catch (SqlException e) {
                    Console.WriteLine(e.Message + "\n");
                   Console.WriteLine(e.StackTrace);
            }
 }
