    //using Oracle.DataAccess.Client;
                                                OracleConnection objConnection = new OracleConnection(System.Configuration.ConfigurationManager.ConnectionStrings["Connection"].ConnectionString);
                                                    using (OracleTransaction OracleTransaction = objConnection.BeginTransaction())
                                                        using (OracleBulkCopy OracleBulkCopy = new OracleBulkCopy(objConnection, OracleBulkCopyOptions.Default, OracleTransaction))
                                                            OracleBulkCopy.DestinationTableName = "OP_TTP_TBL";
                                                            OracleBulkCopy.ColumnMappings.Add("CONTACT_NAME", "CONTACT_NAME");
                                                            OracleBulkCopy.ColumnMappings.Add("APP_NAME", "APP_NAME");

    My code as above with the reference I using in my page, but I always hit error 'The type or namespace name 'OracleBulkCopy' could not be found (are you missing a using directive or an assembly reference?)

    Anyone know how to resolve of this? try to search from Google and tested many way also same..

    If I added //using Oracle.DataAccess;    
    //using Oracle.DataAccess.Client;

    it will showing "Could not load file or assembly 'Oracle.DataAccess' or one of its dependencies. An attempt was made to load a program with an incorrect format."
