摘 要
目前，高校校园里都有跳蚤市场，同学之间可以把闲置不用的物品拿来交易，可以说校园跳蚤市场在高校中可算是一项传统的活动。但是传统的跳蚤市场存在的主要问题有：交易时间固定和交易场所固定，这就对同学之间的交易有了一定的限制。如果利用网络构建一个网络跳蚤市场，在网络上进行交易，那么此问题就得到了很好的解决。
本文设计的是一个基于B/S架构下的网络式跳蚤市场。本系统采用当今流行的C#开发而成，作为一种面向对象的编程语言,它在系统的设计中起到了很重要的作用。另外作为开发环境的Asp.net是一种建立在通用语言上的程序框架，能够只用一台Web服务器来建立强大的Web应用程序。后台数据库使用的是SQL Server 2008，在此数据库中进行相关的操作安全、可靠，为系统安全有效运行提供了保障。本系统为学生提供一个二手商品买卖的场所，主要有四大角色用户：管理员用户、卖家用户、买家用户和匿名用户。管理员和卖家用户、卖家用户和买家用户分别都通过Web Service进行通信。此外，买家用户可以用校园一卡通进行付款，这些为学生的交易提供了方便。

“8090” Flea Market Based on Network
ABSTRACT
At present, there are flea markets in the university campus, students can trade the goods which are not needed on the flea market.We can say that the flea market in the university campus can be regarded as a traditional activity.However,traditional flea market have the main problems as below:Time and place are fixed.These shortcomings have limited the trade between classmates.If constructing a network flea market,concludeing the business in the network,we can solve these problems.
The paper designs the network type flea market which is based on B/S. The development language that this system adopts is C#，as an object-oriented programming language, it plays a very important role in the design. In addition Asp.net , as a kind of development environment ,is a kind of procedure frame based on all-purpose language, can set up strong Web application program only with a Web server. Back-end database using SQL Server 2008, this database-related operation is safe, reliable, safe and effective operation of the system has provided a guarantee. This system offers a place where students can carry on the trade of the second hand goods. There are four major roles of this web site user: administrator user, seller user, buyer user and anonymous users. Administrator and seller, seller and buyer carry on communication respectively through Web Service. In addition, buyer can pay the bill with the all-purpose card of the campus.So the system has offered the convenience to students' trade.
