在asp.net中发送电子邮件作为模板

Sus*_*ant 1 c# asp.net visual-studio-2010

我可以通过我的应用程序发送和接收电子邮件,但其纯文本内容.我想发送用css和div或表装饰的完整格式化内容.怎么做？我使用的是asp.net 3.5 VS2010.

public void Send(string To, string Subject, string Body)
{
    System.Net.Mail.MailMessage m = new System.Net.Mail.MailMessage("mymail@gmail.com", To);
    m.Subject = Subject;
    m.Body = Body;
    m.IsBodyHtml = true;
    m.From = new MailAddress("mymail@gmail.com");

    m.To.Add(new MailAddress(To));
    SmtpClient smtp = new SmtpClient();
    smtp.Host = "198.208.0.***";


    NetworkCredential authinfo = new NetworkCredential("mymail@gmail.com", "password");
    smtp.UseDefaultCredentials = false;
    smtp.Credentials = authinfo;
    smtp.Send(m);
}

像
Send("mynewmail@gmail.com", "testmail", "new test body"); 这样调用这个函数是我的功能.

我认为你缺少的主要是LinkedResource上的MIME内容类型.myMagic.css:

   body {
      background-color: rgb(240,240,240);
      font-family: Verdana,Arial,Helvetica,Sans-serif;
      font-size: 10pt;
   }
   h2 {
      background-color: rgb(255,255,128);
      color: rgb(255,0,0);
   }
   p {
      background-color: rgb(0,0,255);
      color: rgb(0,255,0);
      font-style: italic;
   }

Program.cs中:

using System.Net.Mail;
using System.Net.Mime;

namespace MailMessageHTML
{
    class Program
    {

        private static MailMessage ConstructMessage(string from, string to, string subject)
        {
            const string textPlainContent =@"You need a HTML-capable mail agent to read this message.";
            const string textHtmlContent =@"<html><head><link rel='stylesheet' type='text/css' href='cid:myMagicStyle' />
</head>
<body>
<h2>Hello world!</h2>
<p>This is a test HTML e-mail message.</p>
</body>
</html>
";

   MailMessage result = new MailMessage(from, to, subject, textPlainContent);
   LinkedResource cssResource = new LinkedResource("myMagic.css", "text/css");
   //NOTE: Message encoding adds the surrounding <> on this Id cssResource.ContentId =myMagicStyle";
   cssResource.TransferEncoding = TransferEncoding.SevenBit;

      AlternateView htmlBody = AlternateView.CreateAlternateViewFromString( textHtmlContent , new ContentType("text/html"));
            htmlBody.TransferEncoding = TransferEncoding.SevenBit;
            htmlBody.LinkedResources.Add(cssResource);

            result.AlternateViews.Add(htmlBody);

            return result;
        }

        static void Main(string[] args)
        {
            MailMessage foo = ConstructMessage(
        "sender@foo.com"
                ,"recipient@bar.com"
                , "Test HTML message with style."
                );
            SmtpClient sender = new SmtpClient();
            sender.DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory;
            sender.PickupDirectoryLocation = @"...\MailMessageHTML\bin\Debug\";
            sender.Send(foo);
        }
    }
}

注1:我在上面的消息部分指定了TransferEncoding.SevenBit.你通常不会做这在生产环境中 - 我只是在这里做,所以你可以用记事本读取结果.eml文件里可以看到生成的内容.

注2:许多邮件代理不会尊重邮件部分中链接的样式表.更可靠的方法可能是使用内联样式(即:HTML消息体内的内联...块).

祝好运,
