我有几个图像存储在visual studio项目资源文件夹中,我必须加载它们并在Outlook邮件正文中显示。这是代码:
Bitmap b = new Bitmap(Properties.Resources.MyImage);
ImageConverter ic = new ImageConverter();
Byte[] ba = (Byte[])ic.ConvertTo(b, typeof(Byte[]));
MemoryStream logo = new MemoryStream(ba);
LinkedResource companyImage = new LinkedResource(logo);
companyImage.ContentId = "companyLogo";
mailitem.HTMLBody += "<img src=\"cid:companyLogo\">";
但是,它无法在邮件正文中显示,而是“带红色x的空框”。你能给我一些想法吗?

使用Attachment.PropertyAccessor创建附件并设置PR_ATTACH_CONTENT_ID属性(DASL名称&#34; http://schemas.microsoft.com/mapi/proptag/0x3712001F&#34;)。
您的HTML正文(MailItem.HTMLBody属性)需要通过cid引用该图像附件:
img src =&#34; cid:xyz&#34;
其中xyz是PR_ATTACH_CONTENT_ID属性的值。
查看包含OutlookSpy的现有邮件(单击IMessage按钮)。
attachment = mailitem.Attachments.Add("c:\temp\MyPicture.jpg")
attachment.PropertyAccessor.SetProperty("http://schemas.microsoft.com/mapi/proptag/0x3712001F", "MyId1")
mailitem.HTMLBody = "<html><body>Test image <img src=""cid:MyId1""></body></html>"

也许你可以试试这个。
string htmlBody = "<html><body><h1>Picture</h1><br><img src=\"cid:filename\"></body></html>";
AlternateView avHtml = AlternateView.CreateAlternateViewFromString
(htmlBody, null, MediaTypeNames.Text.Html);
var fileName = Guid.NewGuid.ToString();
var path = Path.Combine(
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)),
fileName);
File.WriteAllBytes(path, Properties.Resources.Pic);
LinkedResource inline = new LinkedResource(path, MediaTypeNames.Image.Jpeg); //Jpeg or something
inline.ContentId = Guid.NewGuid().ToString();
avHtml.LinkedResources.Add(inline);
MailMessage mail = new MailMessage();
mail.AlternateViews.Add(avHtml);
Attachment att = new Attachment(filePath);
att.ContentDisposition.Inline = true;
mail.From = from_email;
mail.To.Add(data.email);
mail.Subject = "Here is your subject;
mail.Body = String.Format(
"Here is the previous HTML Body" +
@"<img src=""cid:{0}"" />", inline.ContentId);
mail.IsBodyHtml = true;
mail.Attachments.Add(att);
