Entity Framework底层操作封装(3)
上面谈了几个类的 封装 ,这次我们讲讲使用的方式。 在实际过程中,我们怎么就能说明我们少了代码的编写呢? 例如我们需要一个类实现某个表的 操作 ,我们只需要继承与我们的Base类就能实现了。 using System;using System.Collections.Generic;using System
上面谈了几个类的封装,这次我们讲讲使用的方式。
在实际过程中,我们怎么就能说明我们少了代码的编写呢?
例如我们需要一个类实现某个表的操作,我们只需要继承与我们的Base类就能实现了。
using System; using System.Collections.Generic; using System.Linq; using System.Text; using NOAS.PublicOpinionMonitor.Access.Common; using NOAS.PublicOpinionMonitor.ENTITY; namespace NOAS.PublicOpinionMonitor.Access { public class ProxyDAL : AccessBase<t_po_monitor_proxy> { public ProxyDAL() : base(strTableName:"t_po_monitor_proxy",ColumsName:@" [monitorid] ,[monitor_name] ,[tkwid] ,[monitor_stardate] ,[monitor_enddate] ,[monitor_datetype] ,[monitor_interval] ,[data_begindate] ,[data_enddate] ,[exec_datetime] ,[monito_days] ,[updatedate] ,[status]") { } public List<t_po_monitor_proxy> getAllMonitorProxy() { return getListByWhere(string.Empty); } } } </t_po_monitor_proxy></t_po_monitor_proxy>
在业务层的使用过程中,就更加简单了。
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace NOAS.PublicOpinionMonitor.BIZ { public class ProxyBLL { public int addMonitorProxy(ENTITY.t_po_monitor_proxy proxyEntity) { new NOAS.PublicOpinionMonitor.Access.ProxyDAL().addEntity(proxyEntity); return proxyEntity.mproxyid; } public int updateMonitorProxy(ENTITY.t_po_monitor_proxy proxyEntity) { new NOAS.PublicOpinionMonitor.Access.ProxyDAL().updateEntity(proxyEntity); return proxyEntity.mproxyid; } } }
从这里也让我更加的喜欢去设计和架构东西。架构让程序编程更美。多想,多做,多看。让我们的代码变得更加清晰。
坚决不做码农,我们是攻城师。

PyCharm is a very popular Python integrated development environment (IDE). It provides a wealth of functions and tools to make Python development more efficient and convenient. This article will introduce you to the basic operation methods of PyCharm and provide specific code examples to help readers quickly get started and become proficient in operating the tool. 1. Download and install PyCharm First, we need to go to the PyCharm official website (https://www.jetbrains.com/pyc

sudo (superuser execution) is a key command in Linux and Unix systems that allows ordinary users to run specific commands with root privileges. The function of sudo is mainly reflected in the following aspects: Providing permission control: sudo achieves strict control over system resources and sensitive operations by authorizing users to temporarily obtain superuser permissions. Ordinary users can only obtain temporary privileges through sudo when needed, and do not need to log in as superuser all the time. Improved security: By using sudo, you can avoid using the root account during routine operations. Using the root account for all operations may lead to unexpected system damage, as any mistaken or careless operation will have full permissions. and

Presumably many users have several unused computers at home, and they have completely forgotten the power-on password because they have not been used for a long time, so they would like to know what to do if they forget the password? Then let’s take a look together. What to do if you forget to press F2 for win10 boot password? 1. Press the power button of the computer, and then press F2 when turning on the computer (different computer brands have different buttons to enter the BIOS). 2. In the bios interface, find the security option (the location may be different for different brands of computers). Usually in the settings menu at the top. 3. Then find the SupervisorPassword option and click it. 4. At this time, the user can see his password, and at the same time find the Enabled next to it and switch it to Dis.

According to news from this site on April 17, TrendForce recently released a report, believing that demand for Nvidia's new Blackwell platform products is bullish, and is expected to drive TSMC's total CoWoS packaging production capacity to increase by more than 150% in 2024. NVIDIA Blackwell's new platform products include B-series GPUs and GB200 accelerator cards integrating NVIDIA's own GraceArm CPU. TrendForce confirms that the supply chain is currently very optimistic about GB200. It is estimated that shipments in 2025 are expected to exceed one million units, accounting for 40-50% of Nvidia's high-end GPUs. Nvidia plans to deliver products such as GB200 and B100 in the second half of the year, but upstream wafer packaging must further adopt more complex products.

This website reported on July 9 that the AMD Zen5 architecture "Strix" series processors will have two packaging solutions. The smaller StrixPoint will use the FP8 package, while the StrixHalo will use the FP11 package. Source: videocardz source @Olrak29_ The latest revelation is that StrixHalo’s FP11 package size is 37.5mm*45mm (1687 square millimeters), which is the same as the LGA-1700 package size of Intel’s AlderLake and RaptorLake CPUs. AMD’s latest Phoenix APU uses an FP8 packaging solution with a size of 25*40mm, which means that StrixHalo’s F

1. Introduction to PDO PDO is an extension library of PHP, which provides an object-oriented way to operate the database. PDO supports a variety of databases, including Mysql, postgresql, oracle, SQLServer, etc. PDO enables developers to use a unified API to operate different databases, which allows developers to easily switch between different databases. 2. PDO connects to the database. To use PDO to connect to the database, you first need to create a PDO object. The constructor of the PDO object receives three parameters: database type, host name, database username and password. For example, the following code creates an object that connects to a mysql database: $dsn="mysq
