"ASP.NET 4.0 完整教程,权威技术指南,适合初学者"
在本书《 Beginning ASP.NET 4 in C# 2010》中,作者Matthew MacDonald详细介绍了ASP.NET 4.0框架的基础知识和核心技术,旨在帮助开发者开始构建ASP.NET网站的旅程。这本书专为那些希望深入理解ASP.NET 4.0的初学者设计,提供了丰富的实践指导和理论讲解。
ASP.NET 4.0是微软.NET Framework的一个重要组成部分,它为Web开发提供了一个强大的平台。此版本引入了许多新特性和改进,包括:
1. **增强的性能**:ASP.NET 4.0通过优化内部工作方式提升了运行时性能,减少了服务器资源的消耗,从而提高了网站的响应速度。
2. **更强大的MVC(Model-View-Controller)框架**:ASP.NET MVC 2与ASP.NET 4.0一起发布,提供了一种更清晰的分离关注点的方法,让开发者能更好地进行测试驱动开发(TDD)。
3. **Web Forms改进**:Web Forms是ASP.NET的核心部分,4.0版本对其进行了许多改进,如控件生命周期的简化、动态数据支持以及更灵活的页面布局。
4. **动态数据(Dynamic Data)**:ASP.NET 4.0引入了动态数据功能,允许快速创建数据驱动的网站,无需编写大量代码即可实现数据验证和UI绑定。
5. **简化部署**:引入了Web Deploy工具,使得部署ASP.NET应用程序变得更加简单和高效。
6. **配置管理**:ASP.NET 4.0的配置系统更加灵活,可以针对不同的环境设置不同的配置,便于在开发、测试和生产环境间切换。
7. **AJAX支持**:ASP.NET 4.0增强了AJAX功能,提供了更多的客户端库和更新的jQuery版本,使开发者能够轻松构建富交互式的Web应用。
8. **编程模型的增强**:包括更强的代码隐藏类,更灵活的页面生命周期,以及更方便的数据绑定机制,如Lambda表达式和LINQ支持。
9. **安全性改进**:增加了对ASP.NET请求验证、跨站脚本攻击(XSS)防护以及跨站请求伪造(CSRF)防护的支持。
10. **全球化与本地化**:ASP.NET 4.0在处理多语言和文化环境方面做了加强,让开发者更容易实现全球化应用。
通过阅读本书,读者将逐步学习如何使用C#语言和ASP.NET 4.0框架来创建功能丰富的Web应用程序,包括如何设计用户界面、处理用户输入、实现数据访问和交互、优化性能以及确保应用程序的安全性。书中包含的实际示例和练习将帮助读者掌握理论知识并将其转化为实践经验。
