在 Web 项目之外使用 Razor

我想使用 Razor 视图引擎生成电子邮件。

根据我所读到的内容，我可以使用这些操作系统项目从我的网站上做到这一点：

• Postal http://aboutcode.net/postal/
• ActionMailer.Net http://geeksharp.com/2011/01/26/actionmailer-net-email-templates-for-the-mvc-crowd/
• Mvc邮件程序 http://www.codeproject.com/KB/aspnet/MvcMailerNuGet.aspx

然而，所有这些都使用用户提交表单并从控制器发送电子邮件的示例。创建电子邮件时似乎需要 ControllerContext。我希望定期在“服务”层中进行生成，所以我怀疑我是否有权访问 ControllerContext。

这可行吗？

Check this http://razorengine.codeplex.com/出去。我将它与模板一起用作嵌入资源，如下所示（但可以修改以在任何地方找到模板）：

public static class MailSender
{
    static MailSender()
    {
        CompilerServiceFactory = new DefaultCompilerServiceFactory();
        TemplateService = new TemplateService(CompilerServiceFactory.CreateCompilerService(), typeof(MailTemplate<>));
    }

    private static ICompilerServiceFactory CompilerServiceFactory { get; set; }
    private static TemplateService TemplateService { get; set; }

    private static ITemplate<T> GetTemplate<T>(T model)
    {
        string path = typeof(T).FullName;

        var assembly = Assembly.GetExecutingAssembly();

        using (var stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(path))
        {
            if (stream == null)
                throw new FileNotFoundException("Mail template not found");

            using (var reader = new StreamReader(stream))
            {
                string source = reader.ReadToEnd();

                return TemplateService.GetTemplate<T>(source, model);
            }
        }
    }

    public static void Send<T>(string to, T model)
    {
        Send(new string[] { to }, new string[] { }, new string[] { }, model);
    }
    public static void Send<T>(string to, string cc, string bcc, T model)
    {
        Send(new string[] { to }, new string[] { cc }, new string[] { bcc }, model);
    }
    public static void Send<T>(string[] to, string[] cc, string[] bcc, T model)
    {
        var template = (MailTemplate<T>)GetTemplate<T>(model);

        template.Execute();

        Trace.WriteLine(string.Format("To: {0} Subject: {1}{3}Body: {2}", string.Join(",", to), template.Subject, template.Result, Environment.NewLine), "Mail");
#if !LOCAL
        using (var message = new MailMessage())
        using (var client = new SmtpClient())
        {
            if (!string.IsNullOrWhiteSpace(template.From))
                message.From = new MailAddress(template.From);

            message.To.Add(string.Join(",", to));

            if (cc != null && cc.Length > 0)
                message.CC.Add(string.Join(",", cc));

            if (bcc != null && bcc.Length > 0)
                message.Bcc.Add(string.Join(",", bcc));

            message.Subject = template.Subject;

            message.Body = template.Result;
            message.IsBodyHtml = true;

            client.Send(message);
        }
#endif
    }
}

public abstract class MailTemplate<TModel> : TemplateBase<TModel>
{
    public string From { get; set; }
    public string Subject { get; set; }
}

model:

public class Contact
{
    public string Name { get; set; }
    public string Email { get; set; }
    public string Text { get; set; }
}

模板：

@inherits Feedback.Lib.Mail.MailTemplate<Feedback.Lib.Mail.Templates.Contact>
@{
    From = string.Format("{0} <{1}>", Model.Name, Model.Email);
    Subject = "Contact request - " + From; 
}

@Model.Text

我为每个模板都有自己的模型，因此很容易通过类名找到它们。我也无法使智能感知工作。
