我正在尝试发送一封带有嵌入图像的电子邮件（不是作为附件文件）。我会发邮件

我正在使用以下代码发送邮件：

internal static void Send(SmtpServerConfigurations configurations, EmailMessage emailMsg)
{
    using (var mail = InitializeMailMessage(emailMsg))
    using (var smtpClient = CreateSmtpClient(configurations))
        smtpClient.Send(mail);
}

private static MailMessage InitializeMailMessage(EmailMessage emailMsg)
{
    var mail = new MailMessage
               {
                   From = new MailAddress(emailMsg.From),
                   Subject = emailMsg.Subject,
                   IsBodyHtml = emailMsg.IsBodyHtml
               };

    mail.To.Add(emailMsg.To);

    AddMessageBody(emailMsg, mail);

    return mail;
}

private static void AddMessageBody(EmailMessage emailMsg, MailMessage mail)
{
    if (emailMsg.IsBodyHtml)
    {
        var body = GetHtmlBody(emailMsg.Body, emailMsg.EmbeddedImages);
        mail.AlternateViews.Add(body);
    }
    else
        mail.Body = emailMsg.Body;
}

private static AlternateView GetHtmlBody(string body, List<EmbeddedImage> embeddedImages)
{
    var alternateView = AlternateView.CreateAlternateViewFromString(body, null,
        MediaTypeNames.Text.Html);

    if (embeddedImages == null) return alternateView;

    foreach (var image in embeddedImages)
    {
        var imageToInline = new LinkedResource(image.Path, MediaTypeNames.Image.Jpeg);
        imageToInline.ContentId = image.Id;
        alternateView.LinkedResources.Add(imageToInline);
    }
    return alternateView;
}

private static SmtpClient CreateSmtpClient(SmtpServerConfigurations config)
{
    var smtpClient = new SmtpClient(config.Host);
    smtpClient.Port = config.PortNo;

    if (config.IsAuthenticationRequired)
        smtpClient.Credentials =
            new NetworkCredential(config.Username, config.Password);
    else
        smtpClient.UseDefaultCredentials = true;

    smtpClient.EnableSsl = false;
    return smtpClient;
}

内部静态无效发送（SmtpServerConfigurations配置，EmailMessage emailMsg）
{
使用（var mail=initializeEmailMessage（emailMsg））
使用（var smtpClient=CreateSmtpClient（配置））
发送（邮件）；
}
专用静态邮件消息初始化EmailMessage（EmailMessage emailMsg）
{
var mail=新邮件消息
{
From=新邮件地址（emailMsg.From），
Subject=emailMsg.Subject，
IsBodyHtml=emailMsg.IsBodyHtml
};
mail.To.Add（emailMsg.To）；
AddMessageBody（emailMsg，mail）；
回信；
}
私有静态void AddMessageBody（EmailMessage emailMsg，MailMessage mail）
{
if（emailMsg.IsBodyHtml）
{
var body=GetHtmlBody（emailMsg.body，emailMsg.EmbeddedImages）；
mail.AlternateViews.Add（body）；
}
其他的
mail.Body=emailMsg.Body；
}
私有静态AlternateView GetHtmlBody（字符串体，列表嵌入图像）
{
var alternateView=alternateView.CreateAlternateViewFromString（正文，null，
MediaTypeNames.Text.Html）；
if（embeddedImages==null）返回alternateView；
foreach（嵌入图像中的var图像）
{
var imageToInline=新的LinkedResource（image.Path，MediaTypeNames.image.Jpeg）；
imageToInline.ContentId=image.Id；
alternateView.LinkedResources.Add（ImageToOnline）；
}
返回备选视图；
}
专用静态SmtpClient CreateSmtpClient（SmtpServerConfigurations配置）
{
var smtpClient=新的smtpClient（config.Host）；
smtpClient.Port=config.PortNo；
if（config.IsAuthenticationRequired）
smtpClient.Credentials=
新的网络凭据（config.Username、config.Password）；
其他的
smtpClient.UseDefaultCredentials=true；
smtpClient.EnableSsl=false；
返回smtpClient；
}

但是使用上述代码发送的邮件的格式不是我想要的格式

我想要的是
