我有一个问题要发送带有html和附件作为嵌入式图像的邮件。我不知道如何使用图像文件夹中的图片作为div的背景。
这是我的代码：
SmtpMail oMail = new SmtpMail("TryIt");
SmtpClient oSmtp = new SmtpClient();
oMail.From = "test@emailarchitect.net";
oMail.To = "<my email>";
oMail.Subject = "test";
SmtpServer oServer = new SmtpServer("<smtp server>");
try
{
// Attachment header = oMail.AddAttachment("d:\mail_header.jpg");
Attachment header = oMail.AddAttachment("images/mail_header.jpg"); // this don't work
Attachment oAttachment = oMail.AddAttachment("d:\bg_content.jpg");
Attachment Footer = oMail.AddAttachment("d:\mail_footer.jpg");
string contentID_header = "header";
header.ContentID = contentID_header;
string contentID = "test001@host";
oAttachment.ContentID = contentID;
string contentID_footer = "footer";
Footer.ContentID = contentID_footer;
//how I can use a pic as background
oMail.HtmlBody = "<html><body>"+
"<div style='background-image:url(" + contentID_header + ");width: 800px;height: 50px'></div>" +
"<div><img src="cid:" + contentID + ""></div>" +
"<div><img src="cid:" + contentID_footer + ""></div>" +
"</body></html>";
oSmtp.SendMail(oServer, oMail);
}
catch (Exception ep)
{
txtSimulate.Text = ep.Message;
}
我使用这段代码，它使用带有替代视图的LinkedResources工作得很好。比硬编码 CIDS 好得多。
检查一下：
System.Net.Mail.MailMessage Mensaje = new System.Net.Mail.MailMessage("mail@host.com",DireccionCorreo);
System.Net.Mail.AlternateView htmlView = System.Net.Mail.AlternateView.CreateAlternateViewFromString(Body, null, "text/html");
System.Net.Mail.LinkedResource logo = new System.Net.Mail.LinkedResource("logoimage.jpg");
logo.ContentId = "logoimage";
htmlView.LinkedResources.Add(logo);
System.Net.Mail.LinkedResource logoExchange = new System.Net.Mail.LinkedResource("logoexchange.png");
logoExchange.ContentId = "logoexchange";
htmlView.LinkedResources.Add(logoExchange);
System.Net.Mail.LinkedResource tut1 = new System.Net.Mail.LinkedResource(Application.StartupPath + "/OutlookGuide/tut1.jpg");
tut1 .ContentId = "tut1";
htmlView.LinkedResources.Add(tut1 );
System.Net.Mail.LinkedResource tut2 = new System.Net.Mail.LinkedResource(Application.StartupPath + "/OutlookGuide/tut2.jpg");
tut2.ContentId = "tut2";
htmlView.LinkedResources.Add(tut2);
Mensaje.AlternateViews.Add(htmlView);
我不知道
asp.net 但是使用PHP，我们将图像转换为Base64编码，然后使用
<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADIA..." />
您必须提供图像的完整路径。
首先，我找到了这个项目。
但基本上，将图像"嵌入"在电子邮件本身中，您需要将其添加为链接资源，并在电子邮件的HTML中引用附加的资源。
