摘 要

随着现代信息技术的发展,Internet日益成为各项事业的发展方向。本论文根据C语言在线学习系统现已存在的问题，对其做全面的分析和整体的介绍。介绍了ASP.NET+SQL2005技术开发该系统及其子系统的整个过程。该系统主要利用了ASP.NET强大的网络数据库访问技术，实现web 交互。系统设计并实现了Server和Client模块。这些模块各自发挥了不同的作用与功能,并以ASP.NET＋C#语言为实例进行了系统实现。

本系统的开发利用SQL2005作为本系统的数据库，它是一个支持多用户的新型数据库，适用于大中规模的数据量需求。学校校园网的建设也为新系统服务器/客户端的结构提供了硬件的支持。

使用Visual Studion.NET作为系统开发的开发环境，它提供完善的指令控制语句、类与对象的支持及丰富的数据类型，给开发高性能系统提供的保障为开发满足客户要求的系统，保证了代码的模块化要求，而代码模块化的提高，非常有利于以后对新系统的扩展与修改。

本课题是基于B/S架构的网站系统开发工具采用VS2005集成开发环境进行开发，配合使用微软的SQL2005数据库作为网站的数据库平台。

Abstract

The development of modern information technology, the Internet has increasingly become a cause the direction of development of the item. In this paper, based on the existing C language on-line learning system to do a comprehensive analysis of the introduction and overall. ASP.NET + SQL2005 technology the whole process of the

development of the system of subsystems. The system mainly utilizes the ASP.NET powerful network database access technology, web interaction. The system was designed and implemented the Server and Client module. These modules have played a different role and functions, and the instance system implementation to ASP.NET + C # language. The development and utilization of the system SQL2005 as the database of the system, it is a support for the new multi-user database, applies to the amount of data needs of medium and large scale. The construction of the campus network also provides hardware support for the new system server / client structure.

To use Visual Studion.NET as a development environment for system development, it provides comprehensive instruction control statements, class and object support and rich data types, and to the development of security systems to meet customer requirements for the development of high-performance systems, to ensure that the code modular requirements, the code modular improve very conducive to future extensions and modifications of the new system.

This topic is VS2005 IDE development tools based on the site of the B / S architecture system development, used in conjunction with Microsoft SQL2005 database as the website's database platform. =
