Save Session variables from business object

Question

Hi All,
 
I need to save the values of BO object into session variables after logged in successfully to the website.
 
Here is my code: 
IList<ConfigurationMaster> pConfigurationMaster = BLLConfigurationCountryandState.Instance.GetConfiguration();
                        Session[ConfigEnum.Country.ToString()] = new KeyValuePair<string, string>(pConfigurationMaster[0].ConfigNameId, pConfigurationMaster[0].ConfigValue);
                        Session[ConfigEnum.State.ToString()] = new KeyValuePair<string, string>(pConfigurationMaster[1].ConfigNameId, pConfigurationMaster[1].ConfigValue);
                        Session[ConfigEnum.City.ToString()] = new KeyValuePair<string, string>(pConfigurationMaster[2].ConfigNameId, pConfigurationMaster[2].ConfigValue);
                        Session[ConfigEnum.AcademicYear.ToString()] = pConfigurationMaster[3].ConfigValue;

Here i don't want to use the pConfigurationMaster[index].configvalue;
 
It's very urgent.Any one please help me in this.
