使用NPOI 操作Excel

个人使用的电脑基本默认安装Excel 操作起来

调用Excel的组件便可.如果是一台服务器.没有安装Excel,也就无法调用Excel组件.

在此推荐第三方插件.NPOI 支持XLS(2007)和XLSX(2012)读写.

读:

using (ExcelHelper excelHelper = new ExcelHelper(ConfigurationManager.AppSettings["ExcelFile"]))
{
var dataTable = excelHelper.ExcelToDataTable(null, true);

}

ConfigurationManager.AppSettings["ExcelFile"]) 指文件位置

ExcelToDataTable(null, true); sheetName指Excel中每个Sheet的名字 isFirstRowColumn指第一行是否是列名

  ExcelHelper.CreateExcel(projectName); 
            创建Excel ，projectName 是Excel名字,路径默认是解决方案下File文件夹
               两个For循环，第一个循环是创建列名，第二个循环是创建列下字段的内容
                   当然这只是创建Datatable
                      所以后面还有两个循环 将每个TABLE中列名放到Excel中的Sheet.以及内容
最后fs1.Write写入Excel

RabbitMQ
  是一种应用程序对应用程序的通信方法
      举个例子
          前端站点向服务站点发起请求。一般服务站点要考虑到并发和数据总量保持运行稳定.
             如果前端的请求发送到Rabbit并做持久化.服务端隔段时间批量响应请求。就大大减少了服务站点的压力
                 接下来的栗子就是A站点向Rabbit发消息并走入队列.然后B站点拉取消息并回应,至于隔多久取，一次取多少条.这部分就没做限制（计数就好）.
                         下面是A站点

   ConnectionFactory factory = new ConnectionFactory();
            factory.HostName = "127.0.0.1";
            //默认端口
            factory.Port = ;
            factory.UserName = "guest";//用户名
            factory.Password = "guest";//密码
            using (IConnection conn = factory.CreateConnection())
            {
                using (IModel channel = conn.CreateModel())
                {
                    //在MQ上定义一个持久化队列，如果名称相同不会重复创建
                    channel.QueueDeclare("MQTest", true, false, false, null);
                    while (true)
                    {
                        string message = string.Format("Message_{0}", Console.ReadLine());
                        byte[] buffer = Encoding.UTF8.GetBytes(message);
                        IBasicProperties properties = channel.CreateBasicProperties();
                        properties.DeliveryMode = ;
                        channel.BasicPublish("", "MQTest", properties, buffer);
                        Console.WriteLine("消息发送成功：" + message);
                    }
                }
            }

消息在Rabbit中.A接触Rabbit,B接触Rabbit.

最终是AB交互.但是过程相互不接触

                    //在MQ上定义一个持久化队列，如果名称相同不会重复创建
                    channel.QueueDeclare("MQTest", true, false, false, null);

                    //在队列上定义一个消费者
                    QueueingBasicConsumer consumer = new QueueingBasicConsumer(channel);
                    //消费队列，并设置应答模式为程序主动应答

    EF

像这个被大家用的滚瓜烂熟的框架.我这会拿出来说似乎有点小儿科.不过我就是要写(还写得贼简单)

Nuget中引入EF

自定义DbContext继承DbContext

    public class HotelDbContext : DbContext
    {
        public HotelDbContext()
                : base("name=ConnCodeFirst")
        {
            Database.SetInitializer(new MigrateDatabaseToLatestVersion<HotelDbContext, Configuration>("ConnCodeFirst"));
        }
        public DbSet<TSM_Admin1111111111111> TSM_Admin { get; set; }

    }

ConnCodeFirst 是数据库连接字符串

Configuration 如下

   internal sealed class Configuration : DbMigrationsConfiguration<HotelDbContext>
    {
        public Configuration()
        {
            // 自动迁移 TRUE code frist
            AutomaticMigrationsEnabled = true;
        }

        protected override void Seed(HotelDbContext context)
        {
            context.TSM_Admin.AddOrUpdate(
       p => p.UserID,
       new TSM_Admin1111111111111 { UserID = "", UserName = "" },
       new TSM_Admin1111111111111 { UserID = "", UserName = "" },
       new TSM_Admin1111111111111 { UserID = "", UserName = "" }
     );
        }
    }

  AutomaticMigrationsEnabled 意思就是找不到数据库的时候自动创建数据库。顺带还会创建初始数据（表和数据）。在Seed中
        说真的很鸡肋.用的很想骂街
              接下来是EF的各种使用方式。。婴儿教学版

 new  Configuration();
            using (var data = new HotelDbContext())
            {

                //查询.全表
                var a = data.TSM_Admin.ToList();

                //插入
                data.TSM_Admin.Add(new TSM_Admin1111111111111 { UserID = "高1030测试" });
                data.SaveChanges();

                //修改
                var model = data.TSM_Admin.Where(b => b.UserID == "高1030测试").First();
                if (model != null)
                {
                    model.UserName = "高1030测试名字";

                    data.Entry<TSM_Admin1111111111111>(model).State = System.Data.Entity.EntityState.Modified;
                    data.SaveChanges();
                }

                //删除
                var delete = data.TSM_Admin.Where(b => b.UserID == "高1030测试").First();
                if (delete != null)
                {
                    var result = data.TSM_Admin.Where(b => b.UserID == delete.UserID).FirstOrDefault();

                    data.TSM_Admin.Remove(result);

                    data.SaveChanges();
                }

                var select = data.Database.SqlQuery<TSM_Admin1111111111111>("select * from tsm_123 ").ToList();

                var insert = data.Database.ExecuteSqlCommand("insert into TSM_Admin(UserID) values('高1030测试')");

            }

能用Dapper。就别用EF..

Attribute。
         很多人都梦想着自定义属于自己的属性.那么
               我用双手成就你的梦想

                   StringLength是自定义属性的名字Attribute是必须加上去的。并且在使用中会被忽视

 [AttributeUsage(AttributeTargets.Property)]
    public class StringLengthAttribute : Attribute
    {
        private int _maximumLength;
        public StringLengthAttribute(int maximumLength)
        {
            _maximumLength = maximumLength;
        }

        public int MaximumLength
        {
            get { return _maximumLength; }
        }
    }

接下来定义使用的实体

   public class People
    {
        [StringLength()]
        public string Name { get; set; }

        [StringLength()]
        public string Description { get; set; }
    }

接下来定义获取属性内容的方法

   public class ValidationModel
    {

        public void Validate(object obj)
        {
            var t = obj.GetType();

            //由于我们只在Property设置了Attibute,所以先获取Property
            var properties = t.GetProperties();
            foreach (var property in properties)
            {

                //这里只做一个stringlength的验证，这里如果要做很多验证，需要好好设计一下,千万不要用if elseif去链接
                //会非常难于维护，类似这样的开源项目很多，有兴趣可以去看源码。
                if (!property.IsDefined(typeof(StringLengthAttribute), false)) continue;

                var attributes = property.GetCustomAttributes(false);
                foreach (var attribute in attributes)
                {
                    //这里的MaximumLength 最好用常量去做
                    var maxinumLength = (int)attribute.GetType().
                      GetProperty("MaximumLength").
                      GetValue(attribute);

                    //获取属性的值
                    var propertyValue = property.GetValue(obj) as string;
                    if (propertyValue == null)
                        throw new Exception("exception info");//这里可以自定义，也可以用具体系统异常类

                    if (propertyValue.Length > maxinumLength)
                        throw new Exception(string.Format("属性{0}的值{1}的长度超过了{2}", property.Name, propertyValue, maxinumLength));
                }
            }

        }
    }

接下来是调用过程

  var people = new People()
            {
                Name = "qweasdzxcasdqweasdzxc",
                Description = "description"
            };
            try
            {
                new ValidationModel().Validate(people);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

这个段子充分解释了如何使用自定义Attribute

核心思想是万物皆可supreme

                HttpRuntime.Cache

开发中很多不常改动的数据。可以考虑将数据从数据库里取出来后的指定时间内存在本地内存中

using System;
using System.Web;
using System.Web.Caching;

namespace Chinamoney.Core
{
    public class CacheHelper
    {
        /// <summary>
        /// 获取数据缓存
        /// </summary>
        /// <param name="cacheKey">键</param>
        public static object GetCache(string cacheKey)
        {
            var objCache = HttpRuntime.Cache.Get(cacheKey);
            return objCache;
        }
        /// <summary>
        /// 设置数据缓存
        /// </summary>
        public static void SetCache(string cacheKey, object objObject)
        {

            objCache.Insert(cacheKey, objObject);
        }
        /// <summary>
        /// 设置数据缓存
        /// </summary>
        public static void SetCache(string cacheKey, object objObject, int Hours)
        {
            try
            {
                if (objObject == null) return;
                var objCache = HttpRuntime.Cache;
                //相对过期
                //objCache.Insert(cacheKey, objObject, null, DateTime.MaxValue, timeout, CacheItemPriority.NotRemovable, null);
                //绝对过期时间
                objCache.Insert(cacheKey, objObject, null, DateTime.Now.AddHours(Hours), TimeSpan.Zero, CacheItemPriority.High, null);
            }
            catch (Exception e)
            {
                Log.Logger.Log("缓存写入异常:",e);
            }
        }
        /// <summary>
        /// 移除指定数据缓存
        /// </summary>
        public static void RemoveAllCache(string cacheKey)
        {
            var cache = HttpRuntime.Cache;
            cache.Remove(cacheKey);
        }
        /// <summary>
        /// 移除全部缓存
        /// </summary>
        public static void RemoveAllCache()
        {
            var cache = HttpRuntime.Cache;
            var cacheEnum = cache.GetEnumerator();
            while (cacheEnum.MoveNext())
            {
                cache.Remove(cacheEnum.Key.ToString());
            }
        }
    }
}

读取

 CacheHelper.GetCache("cacheExtraterritorial") as List<ExtraterritorialDataEntity>;

写入

CacheHelper.SetCache("cacheExtraterritorial", enumerable, result.Count);

清空全部缓存(带名称清理指定缓存，不带名称清理全部缓存)

 CacheHelper.RemoveAllCache("cacheExtraterritorial");

调用方式

              SearchResultCollection data = ADHelper.GetALL(ldap, @name, password);

禁用账号

                          ADHelper.DisableUser(ADHelper.GetOne(ldap, name, password, serach.ChinaName));

       List<T>根据指定字段去重

List<string>去重很容易Distinct就可以

如果是List<T>在实体中根据指定字段判断重复项.如果每次都写循环是不是很累.

在此贴出帮助类

using System.Collections.Generic;

namespace Chinamoney.Core
{
    /// <summary>
    /// 去除重复项
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="x"></param>
    /// <param name="y"></param>
    /// <returns></returns>
    public delegate bool EqualsComparer<T>(T x, T y);
    public class ComparerHelper<T> : IEqualityComparer<T>
    {
        private EqualsComparer<T> _equalsComparer;
        public ComparerHelper(EqualsComparer<T> equalsComparer)
        {
            this._equalsComparer = equalsComparer;
        }
        public bool Equals(T x, T y)
        {
            if (null != this._equalsComparer)
                return this._equalsComparer(x, y);
            else
                return false;
        }
        public int GetHashCode(T obj)
        {
            return obj.ToString().GetHashCode();
        }
    }
}

调用方式

 rows = rows.Distinct(new ComparerHelper<ExtraterritorialDataDto>((x, y) => (null != x && null != y) && (x.senderaddress == y.senderaddress))).ToList();

拉姆达指定的字段就是不能相同的字段，可以根据情景变化

JqueryCache
     Cookie有长度限制4m,
            如果真的有大量数据要存放在客户端Jquery.Cache 是个不错的考虑

    <script src="/webStorageCache/web-storage-cache.js"></script>
        <script src="/webStorageCache/ajax-cache.js"></script>

                     var wsCache = new WebStorageCache();//缓存对象.全局通用
                       wsCache.isSupported() //当前浏览器是否支持缓存
                           wsCache.clear();//清空所有缓存
                               wsCache.set('键', 值, { exp: 时间.单位秒。整数 });
                                     wsCache.get('键')

缓存插入成功后可以再浏览器中看到（开发者工具）

I18N

                     loadProperties(LANGUAGE_CODE);
                  }

$(document).ready(function () {
LANGUAGE_CODE = jQuery.i18n.normaliseLanguageCode({}); //获取浏览器的语言
loadProperties(LANGUAGE_CODE);
})
</script>

来一顿专业的BB压压惊

在HTML中需要设置多国语言的元素上添加ID

properties.name+ LANGUAGE_CODE 就是当前加载的语种文件

如果需要改变语言的话

赋值     LANGUAGE_CODE

重新加载    loadProperties(LANGUAGE_CODE);

页面无刷新喔

完美

　　HTML 自定义属性 DATA-XX

HTML允许我们自定义的属性.都以DATA-开头

举个栗子

再JS中或者直接写HTML

   html += "<li class='cl' dataurl='" + data[i].Content + "' datatitle='" + data[i].Title + "' datadesc='" + data[i].Describe + "' time='" + data[i].ShowTime + "'>"; 

          $('#courseData').append($(html));

栗子中是dataurl，datatitle,datadesc

dataurl或者data-url并没有什么区别。

因为data-xx 浏览器会认为是用户自定义属性。不做任何处理

至于dataxx浏览器根本不认识。所以也不做任何处理

大概就是我开心就好的意思

读 var dataurl = $(this).attr("dataurl");
写 $("div").attr("data-my-value", "使用attr改变的数据");
