Kirim gambar sebaris di email

105

Mengalami masalah pengiriman gambar melalui email sebagai gambar yang disematkan di badan. File gambar ditampilkan sebagai lampiran yang baik-baik saja tetapi bagian gambar sebaris hanya ditampilkan sebagai x merah.

Inilah yang saya miliki sejauh ini

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);

Anda sebenarnya tidak menambahkan LinkedResource ke objek mail; sebagai gantinya, Anda membuatnya tetapi kemudian melampirkan objek Lampiran terpisah.

Satu-satunya masalah dengan kode ini adalah string.Format Anda mengacu inline.ContentId, padahal seharusnya att.ContentId. inlinetidak diperlukan sama sekali. Saya lebih suka pertanyaan Anda daripada semua jawaban, karena Anda benar-benar tidak perlu menggunakan AlternateView.

Gambar saya dilampirkan sebagai ekstensi file bin. Apakah saya melakukan sesuatu yang salah?

Cek link ini. itu memiliki metode siap pakai untuk beberapa lampiran sebaris serta untuk lampiran umum untuk file pdf / excel. stackoverflow.com/questions/33665280/…

Coba ini

 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}"" />", att.ContentId);

 mail.IsBodyHtml = true;
 mail.Attachments.Add(att);

Kode ini tidak berfungsi, gunakan kode di bawah ini dari @ T30, dan perlu diingat ketika Anda menambahkan Alternate View ke MailMessage, tampilan itu akan menjadi badan email Anda dan Anda TIDAK perlu mengisi properti Body.
Eric
@Eric: ada masalah kecil dalam kode ini. di mail.body cukup gunakan att.ContentId alih-alih inline.ContentId

Beberapa kode c # minimal untuk menanamkan gambar, bisa berupa:

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;
}

Saya harus menambahkan jenis pantomim LinkedResourceuntuk membuatnya bekerja di klien web Hotmail / Outlook.com. FWIW, saya mencoba ini juga @Microsoft DN dan ini bekerja lebih baik.

Bagi saya ini berhasil, tetapi saya harus menambahkan ContentType: LinkedResource inline = new LinkedResource (filePath, MediaTypeNames.Image.Jpeg);

Komentar kecil: tidak perlu memanggil NewGuid(), AttachmentBasekelas (yang LinkedResourcediwarisi dari) sudah membuatnya jika diperlukan.

Tambahkan ke LinkedResource ContentType "image / bmp" untuk tidak menerima gambar sebagai file terlampir.

Selain komentar di atas, saya memiliki komentar tambahan berikut:

  • Jangan mencampur Attachments dan AlternativeView, penggunaan atau yang lainnya. Jika Anda mencampurnya, lampiran sebaris akan dirender sebagai unduhan yang tidak dikenal.
  • Meskipun Outlook dan Google mengizinkan gaya HTML standar, "cid:att-001"ini TIDAK berfungsi di iPhone (level tambalan akhir 2016), lebih baik gunakan alfa numerik murni"cid:att-001" -> "cid:att001"

Sebagai tambahan. Rendering Outlook (bahkan Office 2015) (masih merupakan mayoritas yang jelas untuk pengguna bisnis) memerlukan penggunaan HTML gaya TABLE TR TD karena tidak sepenuhnya mendukung model kotak HTML.

Bagus, saya terkesan dengan penelitian Anda.
Hammad Sajid
Ini masih terjadi pada tahun 2020, hanya harus mengganti semua kode LinkedResource / AlternativeView dengan kode Lampiran karena saya juga membutuhkan lampiran file, dan posting ini tampaknya menjadi satu-satunya hal di seluruh internet yang menyebutkan bahwa itu tidak akan berfungsi

Contoh yang lebih minimalis lagi:

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);

Anda perlu menambahkan LinkedResource ke AlternateView

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);

Solusi lain adalah melampirkan gambar sebagai lampiran dan kemudian mereferensikan kode html menggunakan cid. Kode HTML:

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

C # Kode:

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();

Kita semua memiliki gaya pengkodean pilihan kita. Inilah yang saya lakukan:

var pictures = new[]
{
    new { id = Guid.NewGuid(), type = "image/jpeg", tag = "justme", path = @"C:\Pictures\JustMe.jpg" },
    new { id = Guid.NewGuid(), type = "image/jpeg", tag = "justme-bw", path = @"C:\Pictures\JustMe-BW.jpg" }
}.ToList();

var content = $@"
<style type=""text/css"">
    body {{ font-family: Arial; font-size: 10pt; }}
</style>
<body>
<h4>{DateTime.Now:dddd, MMMM d, yyyy h:mm:ss tt}</h4>
<p>Some pictures</p>
<div>
    <p>Color Picture</p>
    <img src=cid:{{justme}} />
</div>
<div>
    <p>Black and White Picture</p>
    <img src=cid:{{justme-bw}} />
</div>
<div>
    <p>Color Picture repeated</p>
    <img src=cid:{{justme}} />
</div>
</body>
";

// Update content with picture guid
pictures.ForEach(p => content = content.Replace($"{{{p.tag}}}", $"{p.id}"));
// Create Alternate View
var view = AlternateView.CreateAlternateViewFromString(content, Encoding.UTF8, MediaTypeNames.Text.Html);
// Add the resources
pictures.ForEach(p => view.LinkedResources.Add(new LinkedResource(p.path, p.type) { ContentId = p.id.ToString() }));

using (var client = new SmtpClient()) // Set properties as needed or use config file
using (MailMessage message = new MailMessage()
{
    IsBodyHtml = true,
    BodyEncoding = Encoding.UTF8,
    Subject = "Picture Email",
    SubjectEncoding = Encoding.UTF8,
})
{
    message.AlternateViews.Add(view);
    message.From = new MailAddress("[email protected]");
    message.To.Add(new MailAddress("[email protected]"));
    client.Send(message);
}

Saya menambahkan kode lengkap di bawah ini untuk menampilkan gambar di Gmail, Thunderbird dan klien email lainnya: 

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)
 {
    // below line was corrected to include the mediatype so it displays in all 
    // mail clients. previous solution only displays in Gmail the inline images 
    LinkedResource res = new LinkedResource(filePath, MediaTypeNames.Image.Jpeg);  
    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;
}
