Question

我想在我的剃刀模板基类上设置与电子邮件相关的属性，可用于发送带有渲染模板的电子邮件。

如何获得对已编译模板的引用？

不，你不能，这是设计的。但您可能想要执行以下操作：

public class EmailDataHolder {
    public string Destination { get; set; }
    public string Subject { get; set; }
}
// In the custom TemplateBase class:
public class EmailTemplateBase<T> : TemplateBase<T>
{
    public EmailDataHolder EmailProperties { get { return Viewbag.DataHolder; } }
    // Or for even simpler templates
    //public string Subject { get { return Viewbag.DataHolder.Subject; }; set { Viewbag.DataHolder.Subject = value; } }
}

// Your code
public static Task SendEmailAsync<T>(string templateName, string destination, T model)
{
    var holder = new EmailDataHolder();
    dynamic viewbag = new DynamicViewBag();
    viewbag.DataHolder = holder;
    holder.Destination = destination;
    var body = Engine.Razor.Run(templateName, typeof(T), model, (DynamicViewBag)viewbag);

    MailMessage msg = new MailMessage();
    msg.To.Add(new MailAddress(holder.Destination));
    msg.Subject = holder.Subject;
    msg.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(body, null, MediaTypeNames.Text.Html));

    SmtpClient smtpClient = new SmtpClient();
    return smtpClient.SendMailAsync(msg);
}

如果您想使用@model，您希望将RazorEngine配置为使用此自定义TemplateBase实施：

config.BaseTemplateType = typeof(EmailTemplateBase<>);

然后你可以像这样使用它：

@inherits EmailTemplateBase<HelloWorldModel>
@{
    Layout = "CI";
    EmailProperties.Subject = "Hello World";
    // with the simpler version
    //Subject = "Hello World";
}
Hello @Model.Name,<br/>
this is a test email...

虽然这并没有真正为您提供编译模板的参考，但它允许您在模板中保存数据并在以后使用它。
