十年河东,十年河西,莫欺少年穷

学无止境,精益求精

近几天,老家河南遭受了近百年一遇的大暴雨,城市内涝严重,希望家乡人挺住,全国人民期待河南尽快好起来,天空放晴。

在此,仅以一篇郑州地铁五号线遭受暴雨侵袭的帖子作为记录。

一个女孩子写在死里逃生后:
今天郑州暴雨,下午四点物业通知要停电所以需要尽快下班,我和同事下楼后发现门口积水已到膝盖,同事说硬着头皮过吧,我犹豫了一下不敢过,所以没有过去,又等了一个多小时终究还是不想在公司留宿,还是淌着到大腿的水过去了,刚坐上地铁以为噩梦结束了,结果地铁刚过了一站,开往第二站的时候就停在中间了!走不动了,车厢就开始慢慢的往里渗水,但是还不太多,我们就在等怎么办?所有人都傻了,后来地铁的工作人员安排我们慢慢撤离,刚走了没多远,又要求我们回去,因为前方的水全部漫过来了,等全部人员上车后车厢的水已经到腰部了,可是噩梦还没有结束,车外面的水一直在涨,也一直在从门缝里往里渗着,慢慢的水越来越多,我们能站在座位上都站在座位上,最后站在座位上水都到胸口了,我真的害怕了,可是最恐怖的不是水而是车厢里的空气越来越少,好多人都出现了呼吸困难的症状,我听到一个阿姨给家人交代银行卡号,交代家里的事情,我想我是不是也要交代一下呢?当时想联系的人很多,想说的事情也很多,但是最后都没有说出口,只能妈妈发了一句,妈妈我可能快不行了,我有点害怕,但是妈妈回过来电话我也不知道说啥,只说还在等救援,就挂了。从六点到八点半一直都处在崩溃的边缘,慢慢的也不用崩溃了,因为我也因为缺氧晕倒了,就在这个时候我妈妈给我打个电话,手机的震动叫醒了我,和妈妈说了两句,有个救援队的叔叔联系上了,我告诉他我们缺氧快不能呼吸了,叔叔说救援队都到了正在想办法,就在这个时候车顶传来了救命的脚步声,有人来了,消防队的叔叔在使劲的砸车厢的玻璃,一下两下无数下,终于砸开了两扇玻璃,有空气了,我们可以恢复呼吸了!然后就听到车厢前面传来越来越多的声音,救援队终于来了,真正遇到生死的时刻才更能体现人性的美好,这么长时间肯定有很多人熬不住了,到处可以听见互相安慰的声音,有获救的机会了,每个人都在喊着让晕倒的人先走,两个男生架着一个晕倒的人,每个人都上去扶一把,把每个晕倒的人都先救出去,然后所有的男生说女生先走,然后男生真的站在两边等着让女生先走,即使是情侣都放开了彼此的手,让女生先走,男生们在后面一个拉着一个女生走,我头晕走不动了,不过停在哪里,不管男生女生都会说一句,你靠着我就可以,看看好多男生和消防员叔叔一直泡在水里,接应一个又一个女生出去,真的是觉得很庆幸,生在华夏生在一个有爱的国度,遇到善良可爱的人,这是我有生以来第一次离死亡那么近,原来只是嘴上说说谁知道明天和意外哪个先来,这次真的是遇到了,原来意外真的会来,真的是害怕了,如果今天真的出不来了,我会很后悔,后悔有太多的事情没有做,后悔太多人没有见,再也不能吃我最爱的麻辣火锅了,更后悔没有和爸爸妈妈奶奶弟弟说句我爱你们,死里逃生后这种感觉更加深刻,既然幸运的我活下来了,那么以后一定要好好的享受生活,好好的珍惜眼前的人和事!好多人发信息关心我,十万分的感谢大家!谢谢!!

好了,祝福河南好起来的同时,我们也进入正题,Sugar的简单封装

新建一个类库,增加类:SugarDbContext

技术图片
using SqlSugar;
using System;
using System.Linq;

namespace AppSugarContext
{
    public class SugarDbContext
    {
        /// 获取连接字符串        
       // private static string Connection = ConfigCommon.Get("WuAnDBContext");
        private static string Connection = "Data Source=58.211.23.172;Initial Catalog=WuAnDBPrd2;Password=mk2XA5+#;User ID=sa;";
        public SugarDbContext()
        {
            Db = new SqlSugarClient(new ConnectionConfig()
            {
                ConnectionString = Connection,
                DbType = DbType.SqlServer,
                InitKeyType = InitKeyType.Attribute,//从特性读取主键和自增列信息
                IsAutoCloseConnection = true,//开启自动释放模式和EF原理一样我就不多解释了

            });
            //调式代码 用来打印SQL 
            Db.Aop.OnLogExecuting = (sql, pars) =>
            {
                Console.WriteLine(sql + "\r\n" +
                    Db.Utilities.SerializeObject(pars.ToDictionary(it => it.ParameterName, it => it.Value)));
                Console.WriteLine();
            };

        }
        //注意:不能写成静态的
        public SqlSugarClient Db;//用来处理事务多表查询和复杂的操作
    }
}
View Code

需要引入Sugar和Json 两个包
