26、ET 功能，随时增强 ASP 应用程序的功能。ASP.NET 是一个已编译的、基于 .NET 的环境，可以用任何与 .NET 兼容的语言（包括 Visual Basic .NET、C# 和 JScript .NET.）创作应用程序。另外，任何 ASP.NET 应用程序都可以使用整个 .NET Framework。开发人员可以方便地获得这些技术的优点，其中包括托管的公共语言运行库环境、类型安全、继承等等。ASP.NET 可以无缝地与 WYSIWYG HTML 编辑器和其他编程工具（包括 Microsoft Visual Studio .NET）一起工作。这不仅使得 Web 开发更加方便，而且还能
27、提供这些工具必须提供的所有优点，包括开发人员可以用来将服务器控件拖放到 Web 页的 GUI 和完全集成的调试支持。微软为ASP.net设计了这样一些策略：易于写出结构清晰的代码、代码易于重用和共享、可用编译类语言编写等等，目的是让程序员更容易开发出Web应用，满足计算向Web转移的战略需要。 ASP.net的新性能 ASP.net提供了稳定的性能、优秀的升级性、更快速的开发、更简便的管理、全新的语言以及网络服务。贯穿整个ASP.net的主题就是系统帮用户做了大部分不重要的琐碎的工作。 全新的构造 新的ASP.net引入受管代码(Managed Code)这样一个全新概念，横贯整个视窗开发平台
28、。受管代码在NGWS Runtime下运行，而NGWS Runtime是一个时间运行环境，它管理代码的执行，使程序设计更为简便。 高效率对于一个程序，速度是一件非常令人渴望的东西。一旦代码开始工作，接下来你就得尽可能地让它运作得快些快些再快些。在ASP中你只有尽可能精简你的代码，以至于不得不将它们移植到一个仅有很少一点性能的部件中。而现在，ASP.net会妥善地解决这一问题。易控制 在ASP.net里，你将会拥有一个“Data-Bounds” (数据约束)，这意味着它会与数据源连接，并会自动装入数据，使控制工作简单易行。语言支持 ASP.net支持多种语言，支持编译类语言，支持比如VB、VC+
29、、C#等，它比这些编译类语言运行速度快，更适合编写大型应用。更好的升级能力 快速发展的分布式应用也需要更快速、更模块化、更易操作、更多平台支持和重复利用性更强的开发，需要一种新的技术来适应不同的系统，网络应用和网站需要提供一种更加强大的可升级的服务。ASP.net能够适应上面的要求。 让你的生活更简单 对于今天的Web程序员来说，最大的挑战就是不断变化的浏览器兼容性以及它们不断升级的复杂性。在保证页面能在所有浏览器下工作的同时，又得尽量使用每个浏览器的最新属性来建立更具交互性的页面，这简直就是一场恶梦。更加可怕的是，需要对不同的用户设备建立不同的网页。最简单的解决办法就是动态地对不同的用户生成
30、不同的输出，或者就是对不同的用户写多个页面。大多数开发者都会选择第一种方法。但是，这就意味着用户的每次点击都会让服务器判断应该向用户显示什么。而通过ASP.net，我们可以看到一个新的服务控制的概念，它封装了一些普通的任务，提供了一种清晰的编程模块，有助于管理和处理不同的用户类型。 什么是 ASP.NET 应用程序？ ASP.NET 将应用程序定义为所有文件、页、处理程序、模块和可执行代码的总和，该应用程序可在 Web 应用程序服务器上的给定虚拟目录（及其子目录）的范围内调用或运行。例如，可在 Web 服务器计算机上的“/order”虚拟目录中发布一个“order”应用程序。对于 IIS，可在
31、 Internet 服务管理器中设置虚拟目录；该目录包含所有子目录，除非子目录本身就是虚拟目录。 Web 服务器上的每个 ASP.NET 框架应用程序都在唯一的 .NET 框架应用程序域中执行，从而保证了类隔离（无版本或命名冲突）、安全沙箱（防止访问特定计算机或网络资源）和静态变量隔离。 ASP.NET 在 Web 应用程序的生存期内维护 HttpApplication 实例池。ASP.NET 自动指派其中的某个实例处理应用程序接收到的每个传入 HTTP 请求。所指派的特定 HttpApplication 实例负责管理请求的整个生存期，并仅在请求完成后才被重新使用。这意味着 HttpApplication 中的用户代码不必是可重入的。 创建应用程序 若要创建 ASP.NET 框架应用程序，可以使用现有虚拟目录或创建新的虚拟目录。例如，如果安装了包含 IIS 的 Windows 2000 Server，则可能有一个 C:InetPubWWWRoot 目录。可以使用 Internet 服务管理器（位于“开始”-“程序”-“管理工具”下）来配置 IIS。右击一个现有目录并选择“新建”（创建新的虚拟目录）或“属性”（提升现有的常规目录）。 通过在虚拟目录中放置一个类似于下面这样的简单 .aspx 页并通过浏览器来访问它，即可开始创建 ASP.NET 应用程序。
