基于C#邮件系统设计
电子邮件客户端软件
摘要
电子邮件在当今社会中扮演了一个很重要的角色。越来越多的人在使用它。而且用它的人数势必会继续增加。虽然，现在已经有很多的邮件收发软件例如著名的FoxMail 但是对于大多数的非专业的人来说它还是有点难度稍嫌负责。因此，我们就利用SMTP和Pop协议从底层开发了这个软件。SMTP全称是简单邮件传输协议，它专门用来发送邮件用的。Pop全称是邮局协议，是专门用于接收邮件的。我主要是负责如何实现发送邮件功能的。MailSend命名空间是我整个程序的核心。它包括两个类。在SmtpMail的类中包含了一个SendMail的方法，它从底层详细地实现了和服务器的交互操作。你既可以用它发送一个纯文本邮件，也可以发送一个带有附件的邮件，理所当然地，你也可以使用不同的SMTP服务器。经过测试，证实此软件是一个支持多收信人，多附件的群发软件。虽然它没有FoxMail那么强大的功能，但是它容易掌握和使用。
Abstract
E-Mail play a very important role in modern times.More and more people are using it,and the number of it will larger and larger.Though there are a lot of software for sending and receiving letters such as FoxMail which are also multifunctional,it is difficult and complicated to the Most of people who are curbstone.For this reason,we do this software with the rock-bottom protocol of SMTP and /Pop. The full name of SMTP is Simple Mail Transfer Protocol.It is Used to sending letters.The full name of Pop is Post Office Protocol which is Special to receive letters.I basically take charge to how to realize the function of sending /letters. A namespace which is named MailSend is the soul of my programe.It includes two classes.A method named sendmial which realize the fuction step by step belongs to the class of /SmtpMail. It detailedly note the track of client exchange to the /server. You can use the software to send either a text E –Mail or a textE-mail with Attachments.You also can Send a letter to many /addressee. In the nature of things,you can use a different SMTP /service. The software I did support multiletters and multisender after I test.It is simplier than FoxMail and other professional softwares,but it is easy to hold and /use.
