該方式直接保存為HTML文件，也可以是文本文件，其它格式效果不是很好

代碼如下:

MailMessage mmsg = new MailMessage();

mmsg.Subject = "郵件標(biāo)題";

mmsg.Body = "郵件內(nèi)容";

mmsg.To.Add("接收郵箱

byte[] bytes = System.Text.Encoding.Default.GetBytes

(@"<table><tr><td width=150>1234567891234567

</td><td width=80>12345678</td></tr></table>");

MemoryStream ms = new MemoryStream(bytes);

ContentType ct = new ContentType();

//附件文件類(lèi)型

ct.MediaType = MediaTypeNames.Text.Html;

//附件名稱(chēng)，可以是其它后綴名

ct.Name = "附件名稱(chēng)" + DateTime.Now.ToString() + ".html";

mmsg.Attachments.Add(new Attachment(ms, ct));

//SMTP簡(jiǎn)單郵件協(xié)議

System.Net.Mail.SmtpClient sc

= new System.Net.Mail.SmtpClient();

sc.Host = "127.0.0.1";//主機(jī)地址

sc.Port = 25;//端口

//發(fā)送郵箱賬號(hào)和密碼

sc.Credentials =

new System.Net.NetworkCredential("account", "password");

//發(fā)送郵箱

mmsg.From = new MailAddress("");

sc.Send(mmsg);

//釋放流資源

ms.Close();

ms.Dispose();

另附上一個(gè).net使用smtp發(fā)送帶附件郵件的實(shí)例

復(fù)制代碼 代碼如下:

public static void sendEmail(string toAddress, string emailbody)

{

var fromAddress = ConfigurationManager.AppSettings["EmailAddress"];

string fromPassword = ConfigurationManager.AppSettings["EmailPassword"].ToString();

const string subject = "Job Recommendation";

var smtp = new SmtpClient

{

Host = ConfigurationManager.AppSettings["SmtpServer"].ToString(),

Port = int.Parse(ConfigurationManager.AppSettings["SmtpPort"]),

EnableSsl = true,

DeliveryMethod = SmtpDeliveryMethod.Network,

UseDefaultCredentials = false,

Credentials = new NetworkCredential(fromAddress, fromPassword)

};

using (var message = new MailMessage(fromAddress, toAddress, subject, HttpUtility.HtmlEncode(emailbody)))

{

smtp.Send(message);

}

}

<add key="EmailAddress" value=" Address

<add key="EmailPassword" value="*********"/> //Emial PWD

<add key="SmtpServer" value="smtp.gmail.com"/>

<add key="SmtpPort" value="587"/>

<--帶附件版本->

var fromAddress = "";

string fromPassword = "yj1989120";

const string subject = "CV";

var smtp = new SmtpClient

{

Host = "smtp.gmail.com",

Port = 587,

EnableSsl = true,

DeliveryMethod = SmtpDeliveryMethod.Network,

UseDefaultCredentials = false,

Credentials = new NetworkCredential(fromAddress, fromPassword)

};

MailMessage email=new MailMessage(fromAddress, "");

email.Subject = "INLINE attachment TEST";

email.IsBodyHtml = true;

string attachmentPath = "C:\\3.jpeg";

Attachment inline = new Attachment(attachmentPath);

inline.ContentDisposition.Inline = true;

inline.ContentDisposition.DispositionType = DispositionTypeNames.Inline;

//inline.ContentId = "1";

//inline.ContentType.MediaType = "image/png";

inline.ContentType.Name = Path.GetFileName(attachmentPath);

email.Attachments.Add(inline);

email.Body = "test";

smtp.Send(email);

email.Dispose();

//如果沒(méi)有路徑，用Stream

Attachment letter = new Attachment(FileUploadLetter.FileContent, FileUploadLetter.PostedFile.ContentType);

letter.ContentDisposition.Inline = true;

letter.ContentDisposition.DispositionType = DispositionTypeNames.Inline;

//inline.ContentId = "1";

letter.ContentType.MediaType = FileUploadLetter.PostedFile.ContentType;

letter.ContentType.Name = Path.GetFileName(FileUploadLetter.PostedFile.FileName);

letter.Name = Path.GetFileName(FileUploadLetter.PostedFile.FileName);
