2、ding. ASP.NET is part of the .NET Framework, and when coding ASP.NET applications you have access to classes in the .NET Framework. You can code your applications in any language compatible with the common language runtime (CLR), including Microsoft Visual Basic, C#, JScript .NET, and J#. These lang
3、uages enable you to develop ASP.NET applications that benefit from the common language runtime, type safety, inheritance, and so on. ASP.NET includes: A page and controls framework The ASP.NET compiler Security infrastructure State-management facilities Application configuration Health monitoring an
4、d performance features Debugging support An XML Web services framework Extensible hosting environment and application life cycle management An extensible designer environment The ASP.NET page and controls framework is a programming framework that runs on a Web server to dynamically produce and rende
5、r ASP.NET Web pages. ASP.NET Web pages can be requested from any browser or client device, and ASP.NET renders markup (such as HTML) to the requesting browser. As a rule, you can use the same page for multiple browsers, because ASP.NET renders the appropriate markup for the browser making the reques
6、t. However, you can design your ASP.NET Web page to target a specific browser, such as Microsoft Internet Explorer 6, and take advantage of the features of that browser. ASP.NET supports mobile controls for Web-enabled devices such as cellular phones, handheld computers, and personal digital assista
7、nts (PDAs). ASP.NET Web pages are completely object-oriented. Within ASP.NET Web pages you can work with HTML elements using properties, methods, and events. The ASP.NET page framework removes the implementation details of the separation of client and server inherent in Web-based applications by pre
8、senting a unified model for responding to client events in code that runs at the server. The framework also automatically maintains the state of a page and the controls on that page during the page processing life cycle. The ASP.NET page and controls framework also enables you to encapsulate common
9、UI functionality in easy-to-use, reusable controls. Controls are written once, can be used in many pages, and are integrated into the ASP.NET Web page that they are placed in during rendering. The ASP.NET page and controls framework also provides features to control the overall look and feel of your
10、 Web site via themes and skins. You can define themes and skins and then apply them at a page level or at a control level. In addition to themes, you can define master pages that you use to create a consistent layout for the pages in your application. A single master page defines the layout and stan
11、dard behavior that you want for all the pages (or a group of pages) in your application. You can then create individual content pages that contain the page-specific content you want to display. When users request the content pages, they merge with the master page to produce output that combines the
12、layout of the master page with the content from the content page. All ASP.NET code is compiled, which enables strong typing, performance optimizations, and early binding, among other benefits. Once the code has been compiled, the common language runtime further compiles ASP.NET code to native code,
13、providing improved performance. ASP.NET includes a compiler that will compile all your application components including pages and controls into an assembly that the ASP.NET hosting environment can then use to service user requests. In addition to the security features of .NET, ASP.NET provides an ad
14、vanced security infrastructure for authenticating and authorizing user access as well as performing other security-related tasks. You can authenticate users using Windows authentication supplied by IIS, or you can manage authentication using your own user database using ASP.NET forms authentication
15、and ASP.NET membership. Additionally, you can manage the authorization to the capabilities and information of your Web application using Windows groups or your own custom role database using ASP.NET roles. You can easily remove, add to, or replace these schemes depending upon the needs of your application.
