反射实现Model修改前后的内容对比
在开发过程中，我们会遇到这样一个问题，编辑了一个对象之后，我们想要把这个对象修改了哪些内容保存下来，以便将来查看和追责。
首先我们要创建一个User类
1 public class User
2 {
3 private string name;
4 public string Name
5 {
6 get { return name; }
7 set { name = value; }
8 }
9 private string age;
10 public string Age
11 {
12 get { return age; }
13 set { age = value; }
14 }
15 private string sex;
16 public string Sex
17 {
18 get { return sex; }
19 set { sex = value; }
20 }
21 }
然后在Main函数中声明并初始化一个User对象
1 User userA = new User()
2 {
3 Name = "李四",
4 Age = "25",
5 Sex = "男",
6 };
因为要对比对象编辑前后的内容，所以需要备份一下这个UserA，我们来个深拷贝
1 User userB = DeepCopyByXml<User>(userA);
1 /// <summary>
2 /// 深拷贝
3 /// </summary>
4 /// <typeparam name="T"></typeparam>
5 /// <param name="obj"></param>
6 /// <returns></returns>
7 public static T DeepCopyByXml<T>(T obj) where T : class
8 {
9 object retval;
10 using (MemoryStream ms = new MemoryStream())
11 {
12 XmlSerializer xml = new XmlSerializer(typeof(T));
13 xml.Serialize(ms, obj);
14 ms.Seek(0, SeekOrigin.Begin);
15 retval = xml.Deserialize(ms);
16 ms.Close();
17 }
18 return (T)retval;
19 }
接下来的工作是修改UserA的属性，然后和UserB对比，利用反射来实现该功能
/// <summary>
/// Model对比
/// </summary>
/// <typeparam Name="T"></typeparam>
/// <param Name="oldModel"></param>
/// <param Name="newModel"></param>
private static void CompareModel<T>(T oldModel, T newModel) where T : class
{
string changeStr = string.Empty;
PropertyInfo[] properties = oldModel.GetType().GetProperties();
Console.WriteLine("--------用户信息修改汇总--------");
foreach (System.Reflection.PropertyInfo item in properties)
{string name = item.Name;
object oldValue = item.GetValue(oldModel);
object newValue = item.GetValue(newModel);
if (!oldValue.Equals(newValue))
{
Console.WriteLine(name + " ：由[" + oldValue + "] 改为 [" + newValue + "]");
}
}
}
从运行结果来看我们已经获取到了修改的内容，美中不足的是“Name”和“Age”，如何以中文显示属性名，接下来将利用C#的特性来实现
新建一个自定义的特性类TableAttribute
/*
参数 validon 规定特性可被放置的语言元素。它是枚举器 AttributeTargets 的值的组合。默认值是 AttributeTargets.All。
参数 allowmultiple（可选的）为该特性的 AllowMultiple 属性（property）提供一个布尔值。如果为 true，则该特性是多用的。默认值是 false（单用的）。
参数 inherited（可选的）为该特性的 Inherited 属性（property）提供一个布尔值。如果为 true，则该特性可被派生类继承。默认值是 false（不被继承）。
*/
[AttributeUsage(AttributeTargets.Class |
AttributeTargets.Field |
AttributeTargets.Property,
AllowMultiple = false,
Inherited = false)]
public class TableAttribute : System.Attribute
{
private string fieldName;
private string tableName;
/// <summary>
/// 表名
/// </summary>
public string TableName
{
get { return tableName; }
set { tableName = value; }
}
/// <summary>
/// 字段名
/// </summary>
public string FieldName
{
get { return fieldName; }
set { fieldName = value; }
}
}
接着修改User类，加上自定义的特性TableAttribute
/// <summary>
/// 用户信息实体类
/// </summary>
[TableAttribute(TableName = "用户信息")]
public class User
{
private string name;
[TableAttribute(FieldName = "姓名")]
public string Name
{
get { return name; }
set { name = value; }
}
private string age;
[TableAttribute(FieldName = "年龄")]
public string Age
{
get { return age; }
set { age = value; }
}
private string sex;
[TableAttribute(FieldName = "性别")]
public string Sex
{
get { return sex; }
set { sex = value; }
}
}
最后修改一下CompareModel这个方法
1 /// <summary>
2 /// Model对比
3 /// </summary>
4 /// <typeparam Name="T"></typeparam>
5 /// <param Name="oldModel"></param>
6 /// <param Name="newModel"></param>
7 private static void CompareModel<T>(T oldModel, T newModel) where T : class
8 {
9 string changeStr = string.Empty;
10 PropertyInfo[] properties = oldModel.GetType().GetProperties();
11 Console.WriteLine("--------用户信息修改汇总--------");
12 foreach (System.Reflection.PropertyInfo item in properties)
13 {
14 TableAttribute tableAttribute = item.GetCustomAttribute<TableAttribute>();
15 string name = item.Name;
16 if (tableAttribute != null)
17 name = tableAttribute.FieldName;
18 object oldValue = item.GetValue(oldModel);
19 object newValue = item.GetValue(newModel);
20 if (!oldValue.Equals(newValue))
21 {
22 Console.WriteLine(name + " ：由[" + oldValue + "] 改为 [" + newValue + "]");
23 }
24 }
25 }
我们看一下运行结果

【API调用】腾讯云短信
在之前介绍的火车票查询工具中，利用邮件和短信将查询结果推送给用户。免费短信的条数只有5条，用完之后只能单独使用邮件提醒。
最近发现腾讯云的福利，简单的介绍一下用法。
腾讯云-》产品-》通信服务-》短信-》开通服务-》添加应用-》创建签名和模板-》等待审核通过-》按照Demo测试
在整个流程中，最耗时的就是创建签名和模板，对个人来说只能选择app、公众号或小程序的方式进行申请，多亏之前折腾过一点小程序，从而闯关成功。
接下来查看官方Demo https://github.com/qcloudsms/qcloudsms/tree/master/demo/csharp

Windows操作系统下Redis服务安装图文详解
Redis下载地址：https://github.com/MSOpenTech/redis/releases
下载msi格式的安装文件。
1.运行安装程序，单击next按钮。
2.勾选接受许可协议中的条款，单击next按钮。
3.选择安装目录，勾选添加到环境变量，单击next按钮。
4.端口号以及防火墙添加例外，单击next按钮。
5.是否设置最大内存限制，默认不勾选，单击next按钮。
6.开始安装，单击Insatll按钮。
7.等待安装，耗时不超过一分钟。
8.安装完成，单击Finsh按钮。
9.安装目录文件如下所示。
10.可以从服务中查看到redis服务已经正常运行。
Redis入门学习
一、软件安装
Redis下载地址：https://github.com/MSOpenTech/redis/releases
因为官方并不支持windows系统，需要从微软的GitHub上下载。
解压缩后文件夹内容如图所示（版本3.2.100）：
最开始会用到的文件有redis-server.exe、redis-cli.exe以及一个配置文件redis.windows.conf。
1）启动redis服务，运行cmd.exe
进入到redis文件夹
cd desttop/redis
启动redis-server.exe 并使用配置文件,出现如下图所示就是启动成功了。
redis-server.exe redis.windows.conf
2）启动客户端，再打开一个cmd.exe
进入到文件夹后启动redis-cli.exe
redis-cli.exe
国际惯例，ping helloworld ，解锁熟练掌握redis的成就。
3）为什么默认使用6379端口
Redis作者antirez同学在twitter上说将在下一篇博文（http://oldblog.antirez.com/post/redis-as-LRU-cache.html）中向大家解释为什么他选择6379作为默认端口号。而现在这篇博文出炉，在解释了Redis的LRU机制之后，如期向大家解释了采用6379作为默认端口的原因。6379在是手机按键上MERZ对应的号码，而MERZ取自意大利歌女Alessia Merz的名字。
二、基本用法
redis是以kev-value形式进行数据存储的，value有字符串、哈希表、列表、集合、有序集合等。
一些命令的使用，可以参考http://doc.redisfans.com/学习。
配置文件的使用，redis.windows-service.conf(以windows服务运行时修改)，
1.密码修改# requirepass foobared //去掉注释#，将foobared替换为你自己的密码2.文件命名修改dbfilename dump.rdb // xxxx.rdb
三、C#使用Redis
1）使用到的第三方dll：
<package id="Newtonsoft.Json" version="9.0.1" targetFramework="net45" /> <package id="StackExchange.Redis" version="1.2.6" targetFramework="net45" />
2）搜集到的RedisHelper方法，增加了批量操作

5 {
6 /// <summary>
7 /// 连接redis库的Number
