您需要将其添加为电子邮件的嵌入式资源并为其创建 HTML View ，以下是帮助您入门的示例:

    private static void AddImageToEmail(MailMessage mail, Image image)
    {
        var imageStream = GetImageStream(image);

        var imageResource = new LinkedResource(imageStream, "image/png") { ContentId = "added-image-id" };
        var alternateView = AlternateView.CreateAlternateViewFromString(mail.Body, mail.BodyEncoding, MediaTypeNames.Text.Html);

        alternateView.LinkedResources.Add(imageResource);
        mail.AlternateViews.Add(alternateView);
    }

    private static Stream GetImageStream(Image image)
    {
        // Conver the image to a memory stream and return.
        var imageConverter = new ImageConverter();
        var imgaBytes = (byte[])imageConverter.ConvertTo(image, typeof(byte[]));
        var memoryStream = new MemoryStream(imgaBytes);

        return memoryStream;
    }
