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;
}
}
}
}
我的HTML文件如下：

</html>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？
