找到一份Jmail收邮件的代码,却看不懂,帮我看看啊,

Question

顶了,
1\SqlDataReader dataReader = this.ExtGetSetting(Username); 获取DataReader对象
2\Database dbase=new Database();实力话一个DB类
3\int mailID=this.GetMailID();  邮件的ID唯一性的

Answer 1

以下几句怎么理解:
1\SqlDataReader dataReader = this.ExtGetSetting(Username);//ExtGetSetting一个函数,返回一个SqlDataReader实例
2\Database dbase=new Database();//DataBase是一个类,估计是进行数据库操作的
3\int mailID=this.GetMailID();//一个整形,代表ID
哪给朋友给我一份可以用的接收邮件的代码吧,搞了好久没搞定,谢谢!

Answer 3

我查了好多的关于jmail收取邮件的问题。给的代码都是和上面的代码一样。但是我自己调试的时候就老是抛异常“This function is not included in this version of jmail.”。我以为是我装的jmail版本太低了。我又在网上下载了最新的jmail。然后进行安装。再测试。但就是不成功。抛出异常的时候就是jpop.Connect（Euname,Epwd,server,port）这里。到底要怎样才可以啊？
