在 C# 的邮件正文中附加图像

问题描述

如何在正文内容中附加图像.我写了下面的代码

How can I attach an image in the body content . I have written the below code

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
string UserName = "xyz@someorg.com";
string Password = "my password";
message.To.Add(new System.Net.Mail.MailAddress("toaddress@toadddress.com"));
message.From = new  System.Net.Mail.MailAddress("fromaddress@fromaddress.com");              
message.Subject = "test subject";
message.Body = "<img src=@'C:\Sunset.jpg'/>";                
message.IsBodyHtml = true;
System.Net.Mail.SmtpClient smtpClient = new System.Net.Mail.SmtpClient();
 smtpClient.Host = "hostname";
 smtpClient.Port = 25;
 smtpClient.Credentials = new System.Net.NetworkCredential(UserName, Password);
 smtpClient.Send(message);

代码很好，因为我也收到了消息，但图像在正文中以 [X] 的形式出现，而不是图像.如何解决这个问题?路径正确吗?

The code is fine as I am receiving the message also but the image is coming as [X] inside the body and not as the image. How to solve this? The path is correct?

推荐答案

    string attachmentPath = Environment.CurrentDirectory + @"	est.png";
    Attachment inline = new Attachment(attachmentPath);
    inline.ContentDisposition.Inline = true;
    inline.ContentDisposition.DispositionType = DispositionTypeNames.Inline;
    inline.ContentId = contentID;
    inline.ContentType.MediaType = "image/png";
    inline.ContentType.Name = Path.GetFileName(attachmentPath);

    message.Attachments.Add(inline);
