话不多说，请看代码：（后面附上项目整体代码，可详细查看。）。

算了，vip文章要评审，还是在这里给朋友们注释一下代码内容吧，方便大家参考使用。

核心代码：

pop3：

//using是个好东西，如果你没有关资源，他自动给你关，特别是对于流来说。pop3其实也是输入流，这里就需要用它来保证一下安全。 
using (var client = new Pop3Client()){client.Connect(PopName, PopPort, true); // 使用SSL连接，不用的话最后一个参数改成false。client.Authenticate(MailMS.AccountName, UPwd);//如果是非ssl连接，这里的密码最好也使用邮箱厂商后台可以设置的链接码。这个链接码在邮箱的pop3说明里面有，imap和smtp的说明里面也有。// 获取邮件数量int count = client.GetMessageCount();Console.WriteLine($"Total messages: {count}");// 获取最新的邮件（索引从0开始）for (int i = 0; i < count; i++){string c0 = "", c1 = "", c2 = "";int key = count - 1 - i;var message = client.GetMessage(key);c1 = message.Subject;c0 = message.From.ToString();c2 = message.Date.ToString();dataGridView1.Rows.Add(key + 1, "",c1,c0,c2);//我的页面有个dataGridView来显示邮件列表，所以这里绑一下数据。Hashtable savedMail = new Hashtable();//这个hashtable用来在页面暂存邮件savedMail.Add("Subject", message.Subject);savedMail.Add("From", message.From.ToString());savedMail.Add("Date", message.Date.ToString());savedMail.Add("text", message.TextBody == null ? "" : message.TextBody);savedMail.Add("html", message.HtmlBody == null ? "" : message.HtmlBody);//附件if (message.Attachments.Count() > 0){savedMail.Add("Attachments", message.Attachments);}else{savedMail.Add("Attachments", null);}mails.Add((key + 1).ToString(), savedMail);//暂存所有邮件}}
