推荐答案
我存储我的所有电子邮件模板我的web应用程序的 ASP.NET MVC剃刀浏览，但作为在光组件，我可以轻松地从任何项目中引用嵌入的资源
I store all my e-mail templates for my web-app as ASP.NET MVC Razor Views, but as embedded resource in a light assembly that I can easily reference from any project.
一个模板看起来像这样（注意本地化）：
A template looks like this (notice the localization):
@model Milkshake.Commerce.Model.Users.UserDto
@using Milkshake.Core.Internationalization;
@using Milkshake.Commerce.Model.Meta;
@if (Language.CurrentForInterface.TwoLetterISOLanguageName.Equals("da"))
{
<h1>Hej @Model.FirstName</h1>
<p>
Din nye brugerkonto til Milkshake Commerce er blevet oprettet.
</p>
<p>
Gå til dine <a href="http://@ShopSettings.Instance.Domain.TrimEnd('/')/Account">konto indstillinger</a>, brug din e-mail adresse som adgangskode og du vil blive videreført til dine konto indstillinger, hvor du kan ændre din adgangskode.
</p>
<p>Ha' en god dag!</p>
<h2>The Milkshake Commerce Team!</h2>
}
else
{
<h1>Hi @Model.FirstName</h1>
<p>
Your new user account for Milkshake Commerce has been created for you.
</p>
<p>
Go to your <a href="http://@ShopSettings.Instance.Domain.TrimEnd('/')/Account">user account page</a>, use your e-mail address as password and you'll be taken directly to your account page where you can change your password.
</p>
<p>Have a nice day!</p>
<h2>The Milkshake Commerce Team!</h2>
}
然后，我有一个大师的模板，名为 _AppEmailTemplate.cshtml ：
@using Milkshake.Commerce.Model.Resources

</html>
要实际发送的电子邮件，我使用 RazorEngine 渲染：
To actually send the e-mail, I use RazorEngine for rendering:
public void SendSystemEmail<T>(string templateName, string subject, string fromName, string recipientEmail, T model)
{
dynamic template = this.GetEmailTemplate(templateName);
string layoutBody = RazorEngine.Razor.Parse(template.Layout as string, model);
string emailBody = RazorEngine.Razor.Parse(template.Template as string, model);
emailBody = layoutBody.Replace(CONTENTSECTIONREPLACETOKEN, emailBody);
PreMailer.Net.PreMailer pm = new PreMailer.Net.PreMailer();
emailBody = pm.MoveCssInline(emailBody, true);
EmailDto email = new EmailDto();
email.Body = emailBody;
email.IsBodyHtml = true;
email.FromEmail = "support@example.com";
email.ReplyToEmail = email.FromEmail;
email.FromName = fromName;
email.RecipientEmail = recipientEmail;
email.Subject = subject;
email.Type = EmailTypes.Transactional;
if (String.IsNullOrWhiteSpace(email.FromName))
{
email.FromName = "Milkshake Software";
}
this.SendMailMessages(new List<EmailDto>() { email }, false);
}
以上code使用我自己的EmailDto对象。在这里，您可以轻松地创建一个 [MailMessage] [2] 实例直接，并用其发送的 [SmtpClient] [3] 。
The above code uses my own EmailDto object. Here you can easily create a [MailMessage][2] instance directly, and send it using the [SmtpClient][3].
此外，为了让所有的电子邮件客户端最好的渲染，我用我自己的 preMailer.Net 库将所有的CSS内联。阅读
Also, to get the best rendering in all e-mail clients, I use my own PreMailer.Net library to move all CSS inline. Read my blog post here, for more information. (Code is on Github)
在GetEmailTemplate做到这一点：
The GetEmailTemplate does this:
/// <summary>
/// Gets the email template.
/// </summary>
/// <param name="templateName">Name of the template.</param>
/// <returns>Returns the e-mail template.</returns>
private dynamic GetEmailTemplate(string templateName)
{
string masterTemplateContents = this.GetTemplateFileContents("_AppEmailTemplate.cshtml");
string templateContents = this.GetTemplateFileContents(templateName + ".html.cshtml");
return new { Layout = masterTemplateContents, Template = templateContents };
}
/// <summary>
/// Gets the template file contents.
/// </summary>
/// <param name="templateFileName">The name of the template file.</param>
/// <returns>Returns the contents of the template file.</returns>
private string GetTemplateFileContents(string templateFileName)
{
return this.GetEmailFileContents("Templates", templateFileName);
}
/// <summary>
/// Gets the email file contents.
/// </summary>
/// <param name="lastNamespaceToken">The last namespace token.</param>
/// <param name="templateFileName">The name of the template file.</param>
/// <returns>
/// Returns the contents of the template file.
/// </returns>
private string GetEmailFileContents(string lastNamespaceToken, string templateFileName)
{
var assembly = Assembly.GetExecutingAssembly();
if (assembly != null)
{
StringBuilder sb = new StringBuilder();
using (StreamReader sr = new StreamReader(assembly.GetManifestResourceStream(String.Format("MyApp.BusinessLogic.Communication.{0}.{1}", lastNamespaceToken, templateFileName))))
{
while (!sr.EndOfStream)
{
var line = sr.ReadLine();
if (!line.StartsWith("@model"))
{
sb.AppendLine(line);
}
}
}
return sb.ToString();
}
return null;
}
