Attaching Image in the body of mail in C#
提问by priyanka.bangalore
How can I attach an image in the body content . I have written the below code
如何在正文内容中附加图像。我写了下面的代码
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
string UserName = "[email protected]";
string Password = "my password";
message.To.Add(new System.Net.Mail.MailAddress("[email protected]"));
message.From = new System.Net.Mail.MailAddress("[email protected]");
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);
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?
代码很好，因为我也收到了消息，但图像以 [X] 的形式出现在正文中，而不是图像。如何解决这个问题？路径是否正确？

string attachmentPath = Environment.CurrentDirectory + @"\test.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);
