前几天刚看过c# 4.0新特性，貌似c# 直到4.0才有的dynamic关键字

flex 3如何使用dynamic

先创建个EmployeeRecord.as,在empty目录下

package empty
{
   public dynamic class EmployeeRecord
   {
   }
}

调用类中，先引入上述类后
在程序中

 var emp:EmployeeRecord = new EmployeeRecord();
                emp.name = "云飞扬";//添加新属性name
                emp.age = 28;//添加新属性age
                emp.address = "###路###号";//添加新属性address
                emp.city = "杭州";//添加新属性city
                emp.state = "HZ";//添加新属性state
                emp.zip = "310012";//添加新属性zip
完整调用代码,还要包含有上面的EmployeeRecord.as

<?xml version="1.0" encoding="utf-8"?>

<mx:Application
    xmlns:mx="http://www.adobe.com/2006/mxml"
   
    viewSourceURL=""
    horizontalAlign="center" verticalAlign="middle"
    width="100%" height="100%"

    <mx:Script>
        <![CDATA[
            import empty.EmployeeRecord;
            private function showProperties():void
            {
               var emp:EmployeeRecord = new EmployeeRecord();
                emp.name = "云飞扬";//添加新属性name
                emp.age = 28;//添加新属性age
                emp.address = "###路###号";//添加新属性address
                emp.city = "杭州";//添加新属性city
                emp.state = "HZ";//添加新属性state
                emp.zip = "310012";//添加新属性zip
               
                var displayInfo:Function =
                    function ():String
                {
                    var str:String;
                    str = "Employee Record:\n";
                    str += "Name: " + emp.name + "\n";
                    str += "Age: " + emp.age + "\n";
                    str += "Address: " + emp.address + "\n";
                    str += "City: " + emp.city + "\n";
                    str += "State: " + emp.state + "\n";
                    str += "Zip: " + emp.zip + "\n";
                   
                    return str;
                }
               
                emp.displayRecord = displayInfo;
                panelPropertyArea.text = emp.displayRecord();
            }
        ]]>
    </mx:Script>
    <mx:Panel id="panel" title="A Simple Use of Package" status="Active"
        height="75%" width="75%"
