我想发送一封正文顶部带有徽标的电子邮件。这是我的方法:
public bool SendEmail(string toAddress)
{
SmtpClient smtpServer = new SmtpClient("the server");
try
{
AlternateView htmlView = AlternateView.CreateAlternateViewFromString("<image src=cid:logo style=\"height: 50px;\"><br>Hello World", null, MediaTypeNames.Text.Html);
LinkedResource imageResource = new LinkedResource(Server.MapPath(@"..\..\images\logo.png"));
imageResource.ContentId = "logo";
htmlView.LinkedResources.Add(imageResource);
smtpServer.Port = port;
smtpServer.Credentials = new NetworkCredential("user", "pass");
smtpServer.EnableSsl = false;
MailMessage message = new MailMessage();
message.To.Add(toAddress);
message.From = new MailAddress("the address");
message.Subject = "Some subject";
message.AlternateViews.Add(htmlView);
message.IsBodyHtml = true;
smtpServer.Send(message);
smtpServer.Dispose();
return true;
}
catch (Exception ex)
{
return false;
}
}
该方法正在发送电子邮件,但图像作为附件发送。我试过这样做:
LinkedResource imageResource = new LinkedResource(Server.MapPath(@"..\..\images\logo.png"), MediaTypeNames.Image.Jpeg);
但是当我在这一行中添加“MediaTypeNames.Image.Jpeg”时,发送的电子邮件根本没有图像。
有人可以帮助我吗?提前致谢!

您可以将图像转换为 base64 并将其添加到 src 中,或者您可以只提供图像所在的页面。

您可以试试图书馆MailKit。使用此库可以很好地发送嵌入的图像。
var stream = new MemoryStream();
image.Save(stream, ImageFormat.Png);
stream.Position = 0;
var resource = builder.LinkedResources.Add(contentId, stream);
resource.ContentId = contentId;
// in the email message, there is img with src="cid:contentId"
嵌入图像的另一个示例是 here。

你可以使用它:
public bool SendEmail(string toAddress)
{
SmtpClient smtpServer = new SmtpClient("the server");
try
{
AlternateView htmlView = AlternateView.CreateAlternateViewFromString("<image src=cid:logo style=\"height: 50px;\"><br>Hello World", null, MediaTypeNames.Text.Html);
LinkedResource imageResource = new LinkedResource(Server.MapPath(@"..\..\images\logo.png"));
imageResource.ContentId = "logo";
htmlView.LinkedResources.Add(imageResource);
smtpServer.Port = 0; //add port here
smtpServer.Credentials = new NetworkCredential("user", "pass");
smtpServer.EnableSsl = false;
MailMessage message = new MailMessage();
message.To.Add(toAddress);
message.From = new MailAddress("the address");
message.Subject = "Some subject";
//add file here
Attachment attachment = new Attachment("c://image");
attachment.ContentDisposition.Inline = true;
message.Attachments.Add(attachment);
message.AlternateViews.Add(htmlView);
message.IsBodyHtml = true;
smtpServer.Send(message);
smtpServer.Dispose();
return true;
}
catch (Exception ex)
{
return false;
}
}
