C# -- 使用委托 delegate 执行异步操作
委托是一种安全地封装方法的类型，它与 C 和 C++ 中的函数指针类似。与 C 中的函数指针不同，委托是面向对象的、类型安全的和保险的。
委托的类型由委托的名称定义。
1. 使用委托异步执行方法
    class Program
        public delegate void myWorking(string s);
        static void Main(string[] args)
            Console.WriteLine("主线程开始....线程ID:{0}", Thread.CurrentThread.ManagedThreadId);
            myWorking myWork1 = new myWorking(w1 => Working(w1));
            myWorking myWork2 = new myWorking(w2 => Working(w2));
            myWorking myWork3 = new myWorking(w3 => Working(w3));
            myWorking myWork4 = new myWorking(w4 => Working(w4));
            myWorking myWork5 = new myWorking(w5 => Working(w5));
            //回调函数
            AsyncCallback callback=new AsyncCallback(s=>Console.WriteLine("执行完成，线程ID:{0}",Thread.CurrentThread.ManagedThreadId));
            //BeginInvoke异步执行，会新启动其他线程去执行代码
            myWork1.BeginInvoke("唱歌", callback,null);
            myWork2.BeginInvoke("写代码", callback, null);
            myWork3.BeginInvoke("查资料", callback, null);
            myWork4.BeginInvoke("交作业", callback, null);
            myWork5.BeginInvoke("检查", callback, null);
            Console.WriteLine("主线程结束....线程ID:{0}", Thread.CurrentThread.ManagedThreadId);
            Console.ReadKey();
        private static void Working(string strWork)
            Console.WriteLine(strWork+".....线程ID:{0}",Thread.CurrentThread.ManagedThreadId);
            Thread.Sleep(3000);
2. 执行结果：
JavaScript -- 原型：prototype的使用
JavaScript -- 原型：prototype的使用
在 JavaScript 中，prototype 是函数的一个属性，同时也是由构造函数创建的对象的一个属性。 函数的原型为对象。 它主要在函数用作构造函数时使用。
可以使用 prototype 属性向对象添加属性和方法，甚至于已创建的对象也是如此。
1. 举例：
<!doctype html>
  <meta charset="UTF-8">
  <title>Document</title>
  <script type="text/javascript">
        function Person(name,age,email)
            this.Name=name;
            this.Age=age;
            this.Email=email;
        var p1= new Person('小胡子',20,'xiaohuzi@test.com');
        Person.prototype.Address='China';
        alert(p1.Name+'  '+p1.Age+'  '+p1.Email+'  '+p1.Address);
  </script>
 </head>
2. 运行结果:
DBHelper类连接数据库
 1、执行多条SQL语句，实现数据库事务
 2、执行一条计算查询结果语句，返回查询结果（object）
 3、执行查询语句，返回SqlDataReader ( 注意：调用该方法后，一定要对SqlDataReader进行Close )
 4、执行查询语句，返回DataTable
 5、执行查询语句，返回DataSet
 6、执行存储过程，返回SqlDataReader ( 注意：调用该方法后，一定要对SqlDataReader进行Close )
 7、执行存储过程，带参数
 8、构建 SqlCommand 对象(用来返回一个结果集，而不是一个整数值)
 9、执行存储过程，返回影响的行数
10、创建 SqlCommand 对象实例(用来返回一个整数值)

MVC View中获取action、controller、area名称、参数
获取控制器名称：
ViewContext.RouteData.Values["controller"].ToString();
获取Action名称：
ViewContext.RouteData.Values["action"].ToString();
获取路由参数值：
ViewContext.RouteData.Values[名称].ToString();
如：ViewContext.RouteData.Values["ID"].ToString(); 获取ID的值
 获取area名称
在代码中：
ControllerContext.RouteData.DataTokens["area"]
在View中：
ViewContext.RouteData.DataTokens["area"]
 代码如下：
var action = ViewContext.RouteData.Values["Action"].ToString().ToLower();
var controllerName = ViewContext.RouteData.Values["controller"].ToString().ToLower();
var areaName = ViewContext.RouteData.DataTokens["area"].ToString().ToLower();
var modalID = Request["ModalID"];//举例，url如 edit?modalid=1
