大学二手商品交易平台是采用了ASP。NET技术，使用B/S架构，在Microsoft 。NET Framework框架内运用C#语言以及CSS等技术，实现了网上二手商品交易等基本功能，使用SQL2005数据库建立系统运行所需的后台数据库。通过软件测试，可以保证这个结合信息管理、网上定购等功能于一体的系统是可以使用的。

通过本系统，学生们在Internet上可以突破传统的购买方式来实现二手商品交易，跨越了时间和空间限制，为他们带来了很大的方便，只要呆在家里或是教室，动动手指就能买到自己需要的商品。

本文主要分析了二手商品交易系统的开发平台及其发展趋势，介绍了二手商品交易系统系统设计与实现中的需求分析，本系统的整体设计，系统的工作原理及组成，系统的设计与实现，系统的测试等。

ABSTRACT With the development of Internet, the network Network has gradually become an important part of people's work and life。 What comes is the urgent need for better and more convenient and fast way of shopping, hope can in the shortest possible time to get the most satisfactory products。 Therefore, online shopping has become something that people aspire to。 

The secondary trading platform of Jiangsu university of science and technology is an online shopping system based on B/S mode and ASP。NET technology。 In the Microsoft。 Net framework, we use C# language and CSS technology to realize the online purchase of secondary trading and other basic functions。 The system uses SQL2005 database to create the back-end database。 By software testing, the system can be basically guaranteed to be used。

By the system, students can break through the traditional way to buy second-hand goods transactions in Internet, spanning time and space constraints, which brought great convenience for the customers, just stay at home or in the classroom, fingertips can buy their merchandise needs。

This thesis mainly analyzes the demands of the secondary trading platform of Jiangsu university of science and technology development platform and its development trend, introduces the secondary trading platform of Jiangsu university of science and technology design and implementation of requirements analysis, system overall design, the composition and working principle of the system, the realization of the system design and the system testing。

Keywords: Online-shopping, database, asp。net, B / S Architecture
