我来评论这本书：
内容提要：
这是一本代码详尽的程序开发人员用书，其最大特点是使用大量“商业级”的程序代码来传授企业应用程序的开发技巧。书中所有的示例都分别提供C#和Visual Basic.NET两种语言的代码，便于读者的对比学习。本书的第一部分简明地介绍了ASP.NET框架，第二部分以大量的代码实例讨论ASP.NET的各个方面，最后是使用广泛的Microsoft .NET名字空间的完全参考。本书涉及ASP.NET的全面细节，主要包括通用语言运行时、确认控件、Web控件、列表控件、用户控件、组件构建、ADO.NET和XML Web服务等。
代码详尽是本书的特点，书中的代码可以从原出版商的站点下载。本书是Web开发人员编程中随时查阅的必备手册用书。
