embedding image in body of email from vb.net
提问by vbNewbie
I have rigorously searched for a soln on this but cannot get this to work. I am trying to send an email from within a vb.net application where an image is embedded in the body of the email. I get it to work as an attachment but in outlook and other email clients, the image does not show. The image is stored locally and I wonder if that has anything to do with it. I tried adding the image within a string first and that did not work;
我已经对此进行了严格的搜索，但无法使其正常工作。我正在尝试从 vb.net 应用程序中发送电子邮件，其中图像嵌入在电子邮件正文中。我让它作为附件工作，但在 Outlook 和其他电子邮件客户端中，图像没有显示。图像存储在本地，我想知道这是否与它有关。我尝试先在字符串中添加图像，但没有用；
emailString.AppendLine()
emailString.AppendLine()
emailString.AppendLine("<br />")
emailString.AppendLine("<br />")
emailString.AppendLine("<img src =""cid:C:\Users\Public\Pictures\Sample Pictures\br1.gif"" alt='STUPID IMAGE'>")
then tried a different way with linkedresource
然后用链接资源尝试了不同的方式
Sub SendEmail(ByVal errorMessage As String)
Dim mail As New MailMessage()
mail.From = New MailAddress("[email protected]", "**DAILY STATS**")
mail.Subject = "STATS ALERT"
mail.To.Add("[email protected]")
mail.IsBodyHtml = True
'mail.Body = "TEST EMAIL" 'errorMessage
'mail.BodyEncoding = Encoding.UTF8
smptpServer.Timeout = 30000
smptpServer.Credentials = New NetworkCredential("me", "person")
Dim imageBody As String = " <img src =""cid:C:\Users\Public\Pictures\Sample Pictures\br1.gif"">"
Dim htmlView As System.Net.Mail.AlternateView = System.Net.Mail.AlternateView.CreateAlternateViewFromString(errorMessage, Nothing, "text/html")
Dim plainTextView As System.Net.Mail.AlternateView = System.Net.Mail.AlternateView.CreateAlternateViewFromString(errorMessage, Nothing, "text/plain")
Dim imageResource As New System.Net.Mail.LinkedResource("C:\Users\Public\Pictures\Sample Pictures\br1.gif", MediaTypeNames.Image.Gif)
Dim attachment As System.Net.Mail.Attachment
attachment = New System.Net.Mail.Attachment("C:\Users\Public\Pictures\Sample Pictures\br1.gif")
mail.Attachments.Add(attachment)
'imageResource.ContentId = "HDIImage"
htmlView.LinkedResources.Add(imageResource)
htmlView.TransferEncoding = Net.Mime.TransferEncoding.Base64
htmlView.ContentType = New System.Net.Mime.ContentType("text/html")
'mail.AlternateViews.Add(plainTextView)
mail.AlternateViews.Add(htmlView)
Try
smptpServer.Send(mail)
Catch ex As Exception
If ex.Message.Contains("Timeout") Then
Exit Sub
End If
End Try
I even changed the image type from png to gif. The normal manually created html tables work when appending it to the string but this above way does not work.
我什至将图像类型从 png 更改为 gif。正常的手动创建的 html 表在将其附加到字符串时工作，但上述方法不起作用。
Only this appears:

It seems to me that if your image goes attached to the email, your srcattribute should be "cid:imagename.png", withouta disk path. Take a look at this: embedding image in html email
在我看来，如果您的图片附加到电子邮件中，您的src属性应该是“cid:imagename.png”，没有磁盘路径。看看这个：embedding image in html email
