Problem beim Senden eines Bildes per E-Mail als eingebettetes Bild im Textkörper. Die Bilddatei wird als Anhang angezeigt, der in Ordnung ist, aber der Inline-Bildteil wird nur als rotes x angezeigt.Inline-Bild in E-Mail senden

Hier ist, was ich bisher

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);

Sie sind nicht wirklich die LinkedResource an den Mail-Objekt angehängt; Stattdessen erstellen Sie es, fügen dann aber ein separates Attachment-Objekt hinzu. –

+2

Das einzige Problem mit diesem Code ist, dass Ihr string.Format 'inline.ContentId' referenziert, wenn es tatsächlich' att.ContentId' sein sollte. 'inline' ist überhaupt nicht erforderlich. Ich ziehe deine Frage allen Antworten vor, da du wirklich kein 'AlternateView' verwenden musst. –

Versuchen Sie, diese

string htmlBody = "<html><body><h1>Picture</h1><br><img src=\"cid:filename\"></body></html>"; 
AlternateView avHtml = AlternateView.CreateAlternateViewFromString 
    (htmlBody, null, MediaTypeNames.Text.Html); 

LinkedResource inline = new LinkedResource("filename.jpg", MediaTypeNames.Image.Jpeg); 
inline.ContentId = Guid.NewGuid().ToString(); 
avHtml.LinkedResources.Add(inline); 

MailMessage mail = new MailMessage(); 
mail.AlternateViews.Add(avHtml); 

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);

Dieser Code funktioniert nicht, verwenden Sie den folgenden Code von @ T30, und beachten Sie, wenn Sie Alternative Ansicht zu MailMessage hinzufügen diese Ansicht wird der Körper Ihrer E-Mail und Sie müssen nicht füllen die Body-Eigenschaft. – Eric

Sie benötigen diese die LinkedResource in eine Alternate

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);

Die minimale C# -Code ein Bild einbetten können sein:

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("[email protected]"); 
    mail.To.Add("[email protected]"); 
    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);

Ich musste der 'LinkedResource' einen Mime-Typ hinzufügen, damit er im Hotmail/Outlook.com-Webclient funktioniert. FWIW, ich habe das genauso versucht wie @Microsoft DN und das hat besser funktioniert. – gregtheross

+3

Für mich ist es funktioniert, aber ich hatte das Content hinzuzufügen: LinkedResource inline = new LinkedResource (filePath, MediaTypeNames.Image.Jpeg); –

Kleiner Kommentar: Kein Aufruf von 'NewGuid()' erforderlich, die 'AttachmentBase'-Klasse (von der 'LinkedResource' erbt) erstellt sie bei Bedarf bereits. – Andrew

Zusätzlich zu den obigen Ausführungen, ich habe die folgende addi Kommentare:

  • Mischen Sie nicht Attachments und AlternativeView, Verwendung von oder anderen. Wenn Sie sie mischen, werden die Inline-Anhänge als unbekannte Downloads gerendert.
  • Während Outlook und Google Standard-Stil HTML-erlauben "cid:att-001" dies auf dem iPhone funktioniert NICHT Arbeit (Ende 2016 Patch-Level), eher numerische reine alpha verwendet "cid:att-001" -> "cid:att001"

Als beiseite. Outlook (auch Office 2015) Rendering (immer noch die klare Mehrheit für Business-Benutzer) erfordert die Verwendung von TABLE TR TD HTML-Format, da es das HTML-Box-Modell nicht vollständig unterstützt.

Die andere Lösung hängt das Bild als Anhang an und referenziert es dann HTML-Code mit CID. HTML-Code:

<html> 
<head> 
</head> 
<body> 
    <img width=100 height=100 id=""1"" src=""cid:Logo.jpg""> 
</body> 
</html>

C# Code:

EmailMessage email = new EmailMessage(service); 
email.Subject = "Email with Image"; 
email.Body = new MessageBody(BodyType.HTML, html); 
email.ToRecipients.Add("[email protected]"); 
string file = @"C:\Users\acv\Pictures\Logo.jpg"; 
email.Attachments.AddFileAttachment("Logo.jpg", file); 
email.Attachments[0].IsInline = true; 
email.Attachments(0).ContentId = "Logo.jpg"; 
email.SendAndSaveCopy();

Ein noch minimalistisches Beispiel:

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("[email protected]"), 
    To = { "[email protected]" }, 
    Subject = "yourSubject", 
    AlternateViews = { alternateView } 
}; 

var smtpClient = new SmtpClient(); 
smtpClient.Send(mailMessage);
