深入Lumisoft.NET组件POP3邮件接收与删除操作的使用(2)

if (mime_header.To != null)
                        {
                            StringBuilder sb = new StringBuilder();
                            foreach (Mail_t_Mailbox recipient in mime_header.To.Mailboxes)
                            {
                                string displayname = recipient.DisplayName;
                                string address = recipient.Address;
                                if (!string.IsNullOrEmpty(displayname))
                                {
                                    sb.AppendFormat("{0}({1});", displayname, address);
                                }
                                else
                                {
                                    sb.AppendFormat("{0};", address);
                                }
                            }
                            info.Senders = sb.ToString().Trim(';');
                        }

if (mime_header.Cc != null)
                        {
                            StringBuilder sb = new StringBuilder();
                            foreach (Mail_t_Mailbox recipient in mime_header.Cc.Mailboxes)
                            {
                                string displayname = recipient.DisplayName;
                                string address = recipient.Address;
                                if (!string.IsNullOrEmpty(displayname))
                                {
                                    sb.AppendFormat("{0}({1});", displayname, address);
                                }
                                else
                                {
                                    sb.AppendFormat("{0};", address);
                                }
                            }
                            info.Carboncopy = sb.ToString().Trim(';');
                        }

每封Email会有一个在Pop3服务器范围内唯一的Id,检查这个Id是否存在就可以知道以前有没有接收过这封邮件

复制代码 代码如下:

info.MailUid = message.UID;

每份邮件的头部信息，都会包含一个日期的，如下可以获取到该日期

复制代码 代码如下:

info.Date = mime_header.Date;

标题信息可以通过下面代码获取
