The Design of the Campus Second-hand Goods Trading
Website
Abstract: The campus second-hand goods trading website provides a issuing and trading platform of second-hand goods to the campus users, and has the very important practical significance. Developed a campus second-hand transaction information platform with the ASP.NET technology and the SQL Server database. This system consisted of user setting function, information function, search function and system management function module, and so on. The system interface is simple and generous, easy to use, and running well.
Key Words: Second-hand Transactions; ASP.NET; SQL Server; B/S Architecture
引言
在当前社会上，许多各种类型的电子商务类网站纷纷建立，可以很大程度上解决人们信息资源的闭塞以及地域上的限制[1]。作为大学校园，伴随着学生购买能力的提高和每年的升学和毕业，也存在许多各种类型的二手商品，由于信息交流的落后，很多商品只限于校园公告栏或者请人代为宣传的方式进行交易。这种方式有很多局限性和偶然性，并不能满足二手商品畅通交流的要求，于是一种新的二手商品信息交流方式出现了，就是基于Web的校园网二手商品交易系统[2-4]。

通过这个系统，广大师生用户可以非常方便的发布信息、浏览信息，并且可以对各种二手商品信息进行横向比较。
1 课题研究现状和意义
1.1 课题研究现状
为了满足校园二手商品交易的需求，国内外软件商已经开发出很多比较好的商品化的校园二手商品交易软件[5]。这些校园二手商品交易软件的功能和性能都很完善，它们大多是面向某一地区多所大学而开发的，专业性强、功能分工比较细、操作和使用比较复杂，难以掌握。国内很多中小型大学由于人数限制，地区经济以及地区消费水品比较低[6]。这样的软件对于他们而言就太庞大、太复杂了，应用效果也不是很好。 1.2 研究意义
随着计算机及网络技术的飞速发展，基于互联网的各种应用日益受到了人们的重视，在众多的网络服务中，Web给人耳目一新的感觉，而在这其中，网上购物已经日渐普及，很多人都通过网络来购物，学生是网上购物一个不可忽略的群体，校园二手交易网站为在校学生提供一个供需平台，网站内容丰富，使用方便，学生可以将自己不用的东西放在网上，也可在网上找到自己需要的东西，物美价廉，达到双赢[7]。
2 系统相关技术
网站运用目前比较流行的ASP.NET作为开发平台，在面向对象的基础上，开发设计了校园二手商品交易平台[8]。
ASP.NET是一种建立动态Web应用程序的技术，它是Active Server Page(ASP)的下一个版本，语法在很大程度上与ASP兼容，同时它还提供一种新的编程模型和结构，可生成伸缩性和稳定性更好的应用程序，并提供更好的安全保护。ASP.NET是一个已编译的，基于.NET的环境，可以与任何.NET兼容的语言（包括Visual Basic、C#和Jscript.NET）创作应用程序。易于写出清晰的代码，代码易于重用和共享[9]。ASP.NET具有如下特点： (1) 简易性：使得用户可以快捷地开发Web应用程序；
(2) 可管理性：使得用户可以通过LINQ和MVC等技术对ASP.NET网站进
行管理；
