我在ASP.NET核心2.0类库中使用FluentEmail，它将发送电子邮件通知。
以下是我迄今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("pratik.soni@1rivet.com")
.To("pratik.soni10@gmail.com")
.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;
}
}
}
}

我也试过只将图像路径传递给html中的imgsrc，但这也无效。
请让我知道我在这里失踪了什么。
此外，是否有像 FluentEmail 这样的软件包可以提供 ASP.NET Core 2.0 这样的所有工具？
答案 0 :(得分：1)
你必须使用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("John.Doe@alfki.com");
mail.To.Add("Jane.Doe@alfki.com");
mail.Subject = "An email with an inline image";
smtpClient.Send(mail);
}
修改
适用于.NET Core / Standard。
我不能代表FluentMail;也许你可以没有？
