问题描述
我正在ASP.NET Core 2.0类库中使用 FluentEmail ，该类库将发送电子邮件通知
I'm using FluentEmail in ASP.NET core 2.0 class library which will be sending the Email notification.
以下是我到目前为止尝试过的示例代码:
Below is the sample code I have tried till now:
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;
}
}
}
}
我的HTML文件如下:
My HTML file is as follow:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

</td>

</table>
</td>
</tr>
</table>
<!--/100% body table-->
</body>
</html>
我也尝试过仅将图像路径传递到html中的imgsrc，但这也不起作用.
I have also tried with only passing image path to the imgsrc in html but that is also not working.
请让我知道我在这里想念的东西.
Please let me know what I'm missing in here.
还可以使用 FluentEmail 之类的软件包来提供 ASP.NET Core 2.0 的所有功能吗?
Also, is there any such package like FluentEmail which can provide such all facility with ASP.NET Core 2.0?
推荐答案
您必须使用LinkedResource；看看这个
You have to use a LinkedResource; have a look at this
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);
}
它在.NET Core/Standard中工作.
It works in .NET Core/Standard.
我不能代表FluentMail；也许你可以没有?
I can not speak for FluentMail; maybe you can do without?
