EnterpriseLibrary4 自己封装程序集实现log打印

注意：1）要引用响应的程序集，必须是41的

         2）配置文件

        //第四步

                        if (writer == null)
                        {

                            }
                            catch (ConfigurationErrorsException exception)
                            {
                                TryLogConfigurationFailure(exception);
                                throw;
                            }
                        }
                    }
                }
                return writer;
            }
        }

对应的配置文件，可以通用
