如何使用HTML附件发送电子邮件 [英] How to send email with html attachment
问题描述
ASP.NET /单声道MVC4 C＃应用程序。 HTML文档需要由邮件作为附件发送。
ASP.NET / Mono MVC4 C# application. html documents needs to be sent by a-mail as attachment.
我试过
using (var message = new MailMessage("from@somebody.com",
"to@somebody.com",
"test",
"<html><head></head><body>Invoice 1></body></html>"
))
{
message.IsBodyHtml = true;
var client = new SmtpClient();
client.Send(message);
}
不过，HTML内容将显示在邮件正文中。 如何强制HTML内容显示为电子邮件附件？
But html content appears in message body. How to force html content to appear as e-mail attachment ?
更新
我试过异常的答案，但文件仍显示在Windows邮件在邮件正文只。
I tried Exception answer but document still appears in Windows Mail in message body only.
消息源表明，它包含两部分：
Message source shows that it contains two parts:
----boundary_0_763719bf-538c-4a37-a4fc-e4d26189b18b
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: base64
和
----boundary_0_763719bf-538c-4a37-a4fc-e4d26189b18b
Content-Type: text/html; charset=utf-8
Content-Transfer-Encoding: base64
这两款器件具有相同的base64内容。 如何强制HTML显示为附件？
Both parts have same base64 content. How to force html to appear as attachment?
消息体可以是空的。
推荐答案
如果您想发送HTML作为附件，那么你必须将其添加到的消息 AlternateView 如
If you want to send html as attachment then you have to add it in message AlternateView as shown
AlternateView htmlView = AlternateView.CreateAlternateViewFromString("<html><head></head><body>Invoice 1></body></html>", null, "text/html");
message.AlternateViews.Add(htmlView);
或
只要创建一个 TXT 或 PDF 或 HTML 您要发送作为附件，做的文件： -
Just create a txt or pdf or html document which you want to send as attachment and do as :-
message.Attachments.Add(new Attachment(@"c:\inetpub\server\website\docs\test.pdf"));
也可以创建附件从内存流为（样品code您可以按照您的要求更改）： -
OR you can create attachment from memory stream as(sample code you can change as per your requirement) :-
System.IO.MemoryStream ms = new System.IO.MemoryStream();
System.IO.StreamWriter writer = new System.IO.StreamWriter(ms);
writer.Write("<html><head></head><body>Invoice 1></body></html>");
writer.Flush();
writer.Dispose();
System.Net.Mime.ContentType ct = new System.Net.Mime.ContentType(System.Net.Mime.MediaTypeNames.Text.Html);
System.Net.Mail.Attachment attach = new System.Net.Mail.Attachment(ms, ct);
attach.ContentDisposition.FileName = "myFile.html";
ms.Close();
