reader List change value

I have a reader and in my watch i see the value I am looking for. When I get this value I am trying to change it.
 List<double> yValues = new List<double>();
                    List<string> xValues = new List<string>();
 while (myReader.Read())
                        {
                        
                           




                                    if (xValues.Any(attribute => Convert.ToString(xValues) == "0    "))
                                    {
                                        xValues.Add(Convert.ToString("00001"));
                                        yValues.Add(Convert.ToDouble("000021"));
                                    }
                                    else
                                    {
                                        xValues.Add(Convert.ToString(myReader[0]));
                                        yValues.Add(Convert.ToDouble(myReader[1]));
                                        ExplodedPointList.Items.Add((Convert.ToString(myReader[0])));
                                    }
                    
                          

                                
                          
                        }

What do you mean by "change it"?  Do you mean modify the value, and write back to the data source?
