Atilia - C#邮件定时群发工具

一、Atilia可以做什么

Atilia是一个基于命令行的C#程序,可以发送邮件给一个或多个人。Atilia通过QQ的SMTP服务发送邮件,可以发送附件,可以在配置文件中手动配置收信人。

二、运行Atilia需要什么

在Atilia应用程序的同一目录下,有如下文件

1)一个Attachments文件夹,Atilia会将里面所有的子文件(不含子文件夹及其中文件)视作附件发送给收信人

2)AddressBook.xml文件,用于配置收信人

3)Atilia.html文件,是被发送的邮件文本

这三个文件都位于编译环境中的根目录下,在“程序集属性→生成事件→后期生成事件命令行”中可以将编译环境中的文件复制到Debug目录中

xcopy "$(ProjectDir)Atilia.html" "$(TargetDir)" /Y
xcopy "$(ProjectDir)AddressBook.xml" "$(TargetDir)" /Y
xcopy "$(ProjectDir)Attachments\*" "$(TargetDir)\Attachments\" /Y

三、收信人的配置

收信人配置的规则很简单,保存在AddressBook.xml中

<?xml version="1.0" encoding="gb2312"?>
<!--通讯录-->
<Root Subject="测试邮件">
  <Person Name="江有汜" Email="1239063237@qq.com" />
  <Person Name="淫侠" Email="****@qq.com" />
</Root>

每一个Person代表了一个人,Name是后面Email的一个标识,Email是收信人的地址

Atilia运行后会将邮件发给通信录中存在的每一个Person

四、输入参数

1)没有输入参数:当即准备发送所有的邮件,发送前询问是否发送:要求输入(y/n)

2)两个输入参数:8位的年月日 和 6位的时分秒,如2014年9月30日23时40分00秒,就需要输入如下命令运行:Atilia 20140930 234000
