黑馬程序員_學習日記56_629三層項目（郵件收發、三層總結、HTML）

1、  郵件收發

IMAP：可以在服務器上建文件夾保存接收郵件

通過程序發郵件

1.1純文本郵件

            //創建一封郵件

            MailMessage msg = new MailMessage();

            msg.From = new MailAddress("[email protected]");

            msg.To.Add(new MailAddress("[email protected]"));

            msg.Subject = "去給我帶份飯";

            msg.SubjectEncoding = Encoding.GetEncoding("gb2312");

            msg.Body = "在中午12點之前把飯送過來";

            msg.BodyEncoding = Encoding.GetEncoding("gb2312");

 

            //用SmtpClient發送

            SmtpClient smtp = new SmtpClient();

            smtp.Host = "localhost";

            smtp.Credentials = new NetworkCredential("sk", "123");

            smtp.Send(msg);

            Console.WriteLine("發送完畢！");

 

1.2發HTML文件

1.2.1方式一：

msg.Body = "在中午<font color='red'><h1>12:00</h1></font>之前把飯送過來。";

//設置文本正文是否是html格式

msg.IsBodyHtml = true;

1.2.2方式二：

            msg.Body = "在中午12:00之前把飯送過來";

            msg.BodyEncoding = Encoding.GetEncoding("gb2312");

            //創建一個html格式的文檔

            AlternateView aview = AlternateView.CreateAlternateViewFromString("在中午<font color='red'><h1>12:00</h1></font>之前把飯送過來。", Encoding.GetEncoding("gb2312"), "text/html");

            msg.AlternateViews.Add(aview);

 

1.3發送圖片

            //創建一個html格式的文檔

            AlternateView aview = AlternateView.CreateAlternateViewFromString("在中午<font color='red'><h1>12:00</h1></font>之前把飯送過來。<br/><img src='cid:img001'/>", Encoding.GetEncoding("gb2312"), "text/html");

            //爲郵件中增加一張圖片

            LinkedResource resource = new LinkedResource(@"c:\toyou.jpg");

            resource.ContentId = "img001";

            aview.LinkedResources.Add(resource);

            msg.AlternateViews.Add(aview);

 

 

1.4增加附件

            Attachment attachFile1 = new Attachment(@"c:\1.cs");

            Attachment attachFile2 = new Attachment(@"c:\toyou.jpg");

            msg.Attachments.Add(attachFile1);

            msg.Attachments.Add(attachFile2);

 

2、  三層項目的知識點總結

NPOI、導入導出、MD5實現登錄、數據通過FTP進行同步、拼音檢索（通過數據庫冗餘提高速度）、複合檢索、話術管理（樹狀數據結構存儲、遞歸）、三層、代碼生成器

 

3、HTML
