본문에 포함 된 이미지로 이메일을 통해 이미지를 보내는 데 문제가 있습니다. 이미지 파일은 괜찮은 첨부 파일로 표시되지만 인라인 이미지 부분은 빨간색 x로 표시됩니다.
여기 내가 지금까지 가지고있는 것
LinkedResource inline = new LinkedResource(filePath);
inline.ContentId = Guid.NewGuid().ToString();
MailMessage mail = new MailMessage();
Attachment att = new Attachment(filePath);
att.ContentDisposition.Inline = true;
mail.From = from_email;
mail.To.Add(data.email);
mail.Subject = "Client: " + data.client_id + " Has Sent You A Screenshot";
mail.Body = String.Format(
"<h3>Client: " + data.client_id + " Has Sent You A Screenshot</h3>" +
@"<img src=""cid:{0}"" />", inline.ContentId);
mail.IsBodyHtml = true;
mail.Attachments.Add(att);

이미지를 포함하는 몇 가지 최소한의 C # 코드는 다음과 같습니다.
MailMessage mailWithImg = getMailWithImg();
MySMTPClient.Send(mailWithImg); //* Set up your SMTPClient before!
private MailMessage getMailWithImg() {
MailMessage mail = new MailMessage();
mail.IsBodyHtml = true;
mail.AlternateViews.Add(getEmbeddedImage("c:/image.png"));
mail.From = new MailAddress("yourAddress@yourDomain");
mail.To.Add("recipient@hisDomain");
mail.Subject = "yourSubject";
return mail;
}
private AlternateView getEmbeddedImage(String filePath) {
LinkedResource res = new LinkedResource(filePath);
res.ContentId = Guid.NewGuid().ToString();
string htmlBody = @"<img src='cid:" + res.ContentId + @"'/>";
AlternateView alternateView = AlternateView.CreateAlternateViewFromString(htmlBody, null, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(res);
return alternateView;

위의 의견 외에도 다음과 같은 추가 의견이 있습니다.
- 첨부 파일과 AlternativeView, 또는 다른 것을 함께 사용하지 마십시오. 혼합하면 인라인 첨부 파일이 알 수없는 다운로드로 렌더링됩니다.
- Outlook과 구글은 표준 HTML 스타일 수 있지만
"cid:att-001"
이 않는 NOT 아이폰 (후반 2016 패치 수준) 작업을, 오히려 순수한 알파 숫자를 사용"cid:att-001" -> "cid:att001"
여담으로. Outlook (Office 2015 포함) 렌더링 (여전히 비즈니스 사용자에게는 대부분)은 HTML 상자 모델을 완전히 지원하지 않으므로 TABLE TR TD 스타일 HTML을 사용해야합니다.

더 최소한의 예 :
var linkedResource = new LinkedResource(@"C:\Image.jpg", MediaTypeNames.Image.Jpeg);
// My mail provider would not accept an email with only an image, adding hello so that the content looks less suspicious.
var htmlBody = $"hello<img src=\"cid:{linkedResource.ContentId}\"/>";
var alternateView = AlternateView.CreateAlternateViewFromString(htmlBody, null, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(linkedResource);
var mailMessage = new MailMessage
{
From = new MailAddress("youremail@host.com"),
To = { "recipient@host.com" },
Subject = "yourSubject",
AlternateViews = { alternateView }
};
var smtpClient = new SmtpClient();
smtpClient.Send(mailMessage);

답변
LinkedResource를 AlternateView에 추가해야합니다.
AlternateView alternateView = AlternateView.CreateAlternateViewFromString("<h3>Client: " + data.client_id + " Has Sent You A Screenshot</h3>" +
@"<img src=""cid:{0}"" />", null, "text/html");
alternateView.LinkedResources.Add(inline);
mail.AlternateViews.Add(alternateView);
