无法像在多部分电子邮件中那样发送文本/纯文本

Question

这是不是工作，以发送文本和html多部分电子邮件？然而，用户在gmail中看不到文本/纯文本部分？

Dim M As New Net.Mail.MailMessage("someemail@domain.net", Configuration.ConfigurationSettings.AppSettings("Emailvalidation"))
        M.To.Clear()
        M.To.Add(New Net.Mail.MailAddress(TargetEmail, TargetName))
        Select Case SA.Address.Province
            Case "BC"
                M.Bcc.Add(New Net.Mail.MailAddress("bobs email", "bob"))
        End Select
        M.Subject = Subject

        Dim AV2 = Net.Mail.AlternateView.CreateAlternateViewFromString(M2.Body, New Net.Mime.ContentType("text/html"))
        M.AlternateViews.Add(AV2)

        Dim PT As String = PlainTextTemplate
        Dim AV = Net.Mail.AlternateView.CreateAlternateViewFromString(PT, New Net.Mime.ContentType("text/plain"))
        M.AlternateViews.Add(AV)

我们弄清楚了..。代码实际上是可以工作的。Gmail用户只需切换“消息文本乱码？”让gmail显示纯文本版本。
