591论文网的邮件收发系统的设计基摘要在经济全球化和信息技术飞速发展的今天，通过邮件收发进行信息传递已经成为主流。目前，基于B/S（Browser/Server）模式的MIS（Managementinformationsystem）日益成熟，Web已从静态的HTML到动态的网页，使系统的开发、管理和维护变得非常方便。因此，本系统研究并开发了基于B/S模式的邮件收发程序系统。《邮件收发程序的设计与开发》是一个综合性的程序设计，涉及到界面、系统、数据库、协议、编码等多个方面的内容。本设计前台采用.NET技术,后台数据库采用SQLServer2000，语言采用C#，主要讲述了邮件系统的注册、登陆、管理、发送和接收邮件等基本功能及设计方法。在系统分析中先后用系统的结构图分析了邮件系统，包括功能流程和功能分析，数据库表格。在整个系统的设计中，详细的展现了用户系统的各个功能模块，菜单的设计等。同时在系统的实现中，给出了实现表单中相应的后台数据库服务，前台功能控件的事件及代码以及界面实现的方法。最后，对系统设计的各个功能做了相应测试，并给出了相关设计页面截面的直观图。关键字：C#；邮件系统；SQLServer数据库591论文网(ManagementInformationSystem)basedontheB/S(Browser/Server)isbecomingincreasinglymatureandenterpriseWebhavealreadybeenfromstaticHTMLtodynamicwebsite,whichallowingthesystemtothedevelopment,managementandmaintenancebecameconvenience.Therefore,thissystemresearchedanddevelopedtheinventorymanagementinformationsystembasedontheB/Smode.《ThedesigninganddevelopmentofEmailreceivingandsendingsystem》isacomprehensivedesignprocessinvolvingtheinterface,system,database,agreement,codingandotheraspects.Thedesigninguses.NETtechnology,backgrounddatabaseusingSQLServer2000,C#aslanguage.Itmainlydescribedthemailsystemontheregistration,landing,andmanagement,sendingandreceivingmailandotherbasicfunctionsanddesignmethods.Insystemsanalysisthesystemstructurewasusedtoanalyzethemailsystem,includingthefunctionalprocessesandfunctionalanalysis,databasetables.Duringtheentiresystemdesign,thevarioususersystemfunctionalmodules,menudesignweredetaileddisplayed.Meanwhileinthesystemrealization,thecorrespondingbackstagedatabaseservice,theonstagefunctioneventcontrollerandthecodeaswellasthecontactsurfacerealizationmethodwereofferedintherealizationtablelist.Finally,thecorrespondingtesthasbeengiventosystemdesigneachfunction,andthecorrelationdesignpagesectiondirect-viewingcharthasbeenproduced.Keywords:C#;EmailSystem;SQLServer591论文网目录论文总页数：28页1引言...........................................................................................................................................11.1邮件系统的介绍...............................................................................................................11.2开发概述...........................................................................................................................11.3对电子邮件的现状分析...................................................................................................21.4电子邮件的发展前景.......................................................................................................22开发分析...................................................................................................................................32.1开发背景...........................................................................................................................32.2工作原理分析...................................................................................................................33系统设计...................................................................................................................................43.1模块的划分与功能设计...................................................................................................43.2功能模块的初步设计.......................................................................................................53.2.1前台分析...........................................................63.2.2后台分析............................................................63.3数据库设计.......................................................................................................................73.4模块的组织结构...............................................................................................................94系统详细设计.........................................................................................................................114.1用户“注册”的设计.........................................................................................................114.2用户“登路”的设计.........................................................................................................124.3修改用户密码的设计.....................................................................................................134.4新建文件夹.....................................................................................................................144.5阅读邮件.........................................................................................................................154.6重命名文件夹.................................................................................................................164.7发送邮件.........................................................................................................................174.8邮件用户管理......................................................................................
