存储电子邮件模板的位置

Ela*_*hmi 8 .net asp.net email-templates

我有一个asp.net Web应用程序,它在注册过程中向用户发送几封电子邮件.现在我让它们与代码内联,但我想把它们放在一个中心位置,我可以编辑它们而无需进入VS.

存储这些HTML模板的最佳位置/格式是什么？

我将我的web-app的所有电子邮件模板存储为ASP.NET MVC Razor Views,但作为轻量级程序集中的嵌入式资源,我可以从任何项目轻松引用.

模板看起来像这样(注意本地化):

@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"主"模板,名为_AppEmailTemplate.cshtml:

@using Milkshake.Commerce.Model.Resources

要实际发送电子邮件,我使用RazorEngine进行渲染:

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);
}

上面的代码使用我自己的EmailDto对象.在这里,您可以[MailMessage][2]直接轻松创建实例,并使用[SmtpClient][3].

此外,为了在所有电子邮件客户端中获得最佳渲染,我使用自己的PreMailer.Net库来移动所有CSS内联.阅读我的博客文章,了解更多信息.(代码在Github上)

GetEmailTemplate执行此操作:

/// <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>

/// <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();
