我在ASP.NET Core 2.0类库中使用FluentEmail,它将发送电子邮件通知。

以下是我到目前为止尝试过的示例代码:

using FluentEmail.Core;
using FluentEmail.Razor;
using FluentEmail.Smtp;
using System;
using System.IO;
using System.Net.Mail;
using System.Net.Mime;

namespace FluentEmail
{
    public class EmailNotification : IEmailNotification
    {
        public bool SendEmailNotification()
        {
            try
            {
                //Setup Default sender befault sending the email.
                SmtpClient smtpClient = new SmtpClient
                {
                   Host = "smtp.office365.com",
                   Port = 587,
                   EnableSsl = true,
                   Credentials = new System.Net.NetworkCredential("username", "Password")
                };
                Email.DefaultSender = new SmtpSender(smtpClient);

                Email.DefaultRenderer = new RazorRenderer();

                string imagePath = @"C:\Users\pratik.soni\Downloads\FluentLogo.png";

                Stream stream = new FileStream(imagePath, FileMode.Open, FileAccess.Read);
                stream.Flush();
                stream.Seek(0, SeekOrigin.Begin);

                var attachment = new Core.Models.Attachment()
                {
                    Data = stream,
                    ContentType = "image/png",
                    Filename = "FluentLogo.png",
                    IsInline = true
                };

                var email = Email
                  .From("[email protected]")
                  .To("[email protected]")
                  .Subject("Test")
                  .Body("<html>Inline image here: <img src=\"cid:FluentLogo.png\">" +
                    "<p>You should see an image without an attachment, or without a download prompt, dependig on the email client.</p></html>", true);

                email.Attach(attachment);
                email.Send();
                return true;
            }
            catch (Exception ex)
            {
                return false;
            }

        }
    }
}

我也尝试过仅将图像路径传递到html中的imgsrc,但这也行不通。

请让我知道我在这里想念的东西。

另外,是否有像FluentEmail这样的软件包可以为ASP.NET Core 2.0提供所有此类功能?

最佳答案

您必须使用LinkedResource;看看这个

using (LinkedResource image = new LinkedResource(@"c:\assets\image.jpg", "image/jpeg") { ContentId = "myimage" })
using (MailMessage mail = new MailMessage())
using (SmtpClient smtpClient = new SmtpClient())
{
    smtpClient.Host = "smtp.alfki.com";

    String body = @"
    <html>
        <head></head>
        <body>
        <img src=""cid:myimage"" />
        </body>
    </html>
    ";

    AlternateView view = AlternateView.CreateAlternateViewFromString(body, null, "text/html");
    view.LinkedResources.Add(image);

    mail.IsBodyHtml = true;
    mail.AlternateViews.Add(view);
    mail.From = new MailAddress("[email protected]");
    mail.To.Add("[email protected]");
    mail.Subject = "An email with an inline image";

    smtpClient.Send(mail);
}


编辑:

它适用于.NET Core / Standard。

我不能代表FluentMail;也许你可以没有?
