Question

我正在尝试使用此c＃代码从oracle执行存储过程：

string extension = Filename_Box.Text.Substring(Filename_Box.Text.IndexOf('.'));
                string package_query = "";

                //Run the appropriate package/procedure for the file
                switch(extension)
                {
                    case ".400":
                    case ".500":
                    case ".901":
                    case ".301":
                    case ".303":
                        //Just for testing, remove for production
                        package_query = @"CREDIT_CARD.READ_ECI_CC";
                        //package_query = @"INTERFACE.CREDIT_CARD.READ_ECI_CC";
                        break;
                    case ".200":
                        package_query = @"CREDIT_CARD.READ_ECI_NEWFORMAT_CC";
                        //package_query = @"INTERFACE.CREDIT_CARD.READ_ECI_NEWFORMAT_CC";
                        break;
                    case ".DAT":
                        package_query = @"CREDIT_CARD.READ_INSPRO_CC";
                        //package_query = @"INTERFACE.CREDIT_CARD.READ_INSPRO_CC";
                        break;
                    default:
                        break;
                }

                using (OracleConnection package_connection = new OracleConnection(connection_string))
                {
                    OracleCommand package_command = package_connection.CreateCommand();

                    package_command.CommandText = package_query;
                    package_command.CommandType = System.Data.CommandType.StoredProcedure;

                    package_command.Parameters.Add("p_filename", OracleDbType.Varchar2).Value = Filename_Box.Text;

                    try
                    {
                        package_connection.Open();
                        package_command.ExecuteNonQuery();
                    }

此错误消息的含义是什么？如何解决？详细的错误消息如下：
