SendGrid电子邮件中嵌入的图像

Question

我正在设法用发送网格发送邮件，附件也没问题。但我在将图像嵌入HTML邮件正文时遇到问题

以下是我正在使用的代码，在阅读了有关此问题的各种示例后将它们放在一起。任何人都知道我哪里出错了，问候......

        MemoryStream msLogo = new MemoryStream(obj.logo);
        Bitmap b = new Bitmap(msLogo);
        ImageConverter ic = new ImageConverter();
        Byte[] ba = (Byte[])ic.ConvertTo(b, typeof(Byte[]));
        MemoryStream logo = new MemoryStream(ba);

        AlternateView htmlView = AlternateView.CreateAlternateViewFromString(sBody, null, "text/html");

        LinkedResource imageResource = new LinkedResource(logo);


        var imagelink = new LinkedResource(logo, "image/png");
        imagelink.ContentId = string.Format("logo", myMessage);
        imagelink.TransferEncoding = TransferEncoding.Base64;
        b.Save(logo, ImageFormat.Jpeg);
        logo.Position = 0;
