问题描述

大家好，在发送关于Outlook的电子邮件时需要帮助。电子邮件正文采用html格式，内部嵌入了图像。我的问题是，当我收到关于outlook的电子邮件时，所有图像都是断开的链接。

Hi guys, need help on sending an email on outlook. The email body is in html format and it has an embedded image inside it. My problem is when I received the email on outlook, all of the images are broken link.

public static string getEmailFile(string file)
        {
            //string filename = Session["filename"].ToString();

            Microsoft.Office.Interop.Outlook.Application app = new Microsoft.Office.Interop.Outlook.Application();

            //MailItem item = (MailItem)app.CreateItemFromTemplate(@"C:\Users\orculloj\Desktop\Sample3\" + filename, Type.Missing);
            //MailItem item = (MailItem)app.CreateItemFromTemplate(@"C:\Users\orculloj\Desktop\Sample3\Test.msg", Type.Missing);
            MailItem item = (MailItem)app.CreateItemFromTemplate(@"C:\Users\orculloj\Desktop\Sample2\20160101021244_5541.msg", Type.Missing);

            var a = item.HTMLBody;

            return a;
        }

我的尝试：

What I have tried:

Outlook.Application app = new Outlook.Application();

           MailItem item = (MailItem)app.CreateItemFromTemplate(@"C:\Users\orculloj\Desktop\Sample2\20160101021244_5541.msg", Type.Missing);

           string from = item.ReceivedOnBehalfOfName + "@altisource.com";

           //string body = item.HTMLBody;

           iframe1.Attributes["src"] = "Email.aspx";

           System.Net.Mail.MailMessage mailMsg = new System.Net.Mail.MailMessage();
           MailAddress mailAddress = new MailAddress(from);

           mailMsg.To.Add("[e-mail]");

           mailMsg.From = mailAddress;

           // Subject and Body
           mailMsg.Subject = "Testing mail..";

           string x = "";

           mailMsg.IsBodyHtml = true;
           mailMsg.Body = getEmailFile(x);

           //SmtpMail.SmtpServer = "Internal-Mail.ascorp.com";
           SmtpClient smtpClient = new SmtpClient("Internal-Mail.ascorp.com");

           //smtpClient.EnableSsl = true;

           smtpClient.Send(mailMsg);

推荐答案

我看不到你邮件中包含图片的位置。它必须是多部分邮件，一些部分应该是图像。要在HTML部分中引用图像，您必须使用特殊的URI方案（cid :)来引用邮件部分。请查看我过去的答案：

I don't see where you include images in your mail. It has to be multi-part mail, some parts should be images. To reference images in HTML part, you have to use the special URI scheme (cid:), to reference a mail part. Please see my past answers:
