//注册命名空间

}//Person类的方法
Demo.Person.prototype = {getFirstName: function () {return this._firstName;},getLastName: function () {return this._lastName;},getEmailAddress: function () {return this._emailAddress;},setEmailAddress: function (emailAddress) {this._emailAddress = emailAddress;},getName: function () {return this._firstName + ' ' + this._lastName;},dispose: function () {alert('bye ' + this.getName());},sendMail: function () {var emailAddress = this.getEmailAddress();if (emailAddress.indexOf('@') < 0) {emailAddress = emailAddress + '@example.com';}alert('Sending mail to ' + emailAddress + ' ...');},toString: function () {return this.getName() + ' (' + this.getEmailAddress() + ')';}

//注册类Demo.Person
Demo.Person.registerClass('Demo.Person', null, Sys.IDisposable);//定义Employee类
Demo.Employee = function (firstName, lastName, emailAddress, team, title) {Demo.Employee.initializeBase(this, [firstName, lastName, emailAddress]);this._team = team;this._title = title;

//注册Demo.Employee类，并指定其继承自Demo.Person类
Demo.Employee.registerClass('Demo.Employee', Demo.Person);

var person = new Demo.Person('Jack', 'Smith', 'jack@hotmail.com');

//注册接口
Demo.Trees.IFruitTree.registerInterface('Demo.Trees.IFruitTree');

//使用接口
//类Demo.Trees.FruitTree继承了Demo.Trees.Tree，并实现了接口Demo.Trees.IFruitTree
Demo.Trees.FruitTree.registerClass('Demo.Trees.FruitTree', Demo.Trees.Tree, Demo.Trees.IFruitTree);

//注册命名空间

//注册枚举类型
Demo.Color.registerEnum("Demo.Color");//用法
var color = Demo.Color.Red;
