邮寄RazorEngine.Templating.TemplateCompilationException

Question

我正在尝试使用ASP MVC Postal在后台作业中发送电子邮件，如下所示：

    public void CommentCreated(Comment comment, ApplicationUser user)
    {
        var viewsPath = Path.GetFullPath(HostingEnvironment.MapPath(@"~/Views/Emails"));
        var engines = new ViewEngineCollection();
        engines.Add(new FileSystemRazorViewEngine(viewsPath));

        var emailService = new Postal.EmailService(engines);

        var email = new CommentCreatedEmail
        {
            To = user.Email,
            From = ConfigurationManager.AppSettings["SmtpEMailFrom"],
            Subject = "Comment Created"
            Comment = comment,
            User = user

        };

        emailService.Send(email);

    }

我的视图CommentCreated.cshtml如下：

@model MyApp.Models.CommentCreatedEmail
To: @Model.To
From: @Model.From
Subject: @Model.Subject

<p>
<a href="@Url.Action("Details", "Comment", new { id = @Model.Comment.Id }, "http")">@Url.Action("Details", "Comment", new { id = @Model.Comment.Id }, "http")</a>

​

​

但是我得到了以下错误：

Exception thrown: 'RazorEngine.Templating.TemplateCompilationException' in RazorEngine.dll
Exception thrown: 'System.Web.HttpCompileException' in System.Web.dll

有什么想法吗？

使用异常处理来捕获和识别错误发生的位置

public void CommentCreated(Comment comment, ApplicationUser user)
{
    try{
        var viewsPath = Path.GetFullPath(HostingEnvironment.MapPath(@"~/Views/Emails"));
        var engines = new ViewEngineCollection();
        engines.Add(new FileSystemRazorViewEngine(viewsPath));

        var emailService = new Postal.EmailService(engines);

        var email = new CommentCreatedEmail
        {
            To = user.Email,
            From = ConfigurationManager.AppSettings["SmtpEMailFrom"],
            Subject = "Comment Created"
            Comment = comment,
            User = user

        };

        emailService.Send(email);
    }
    catch(TemplateCompilationException ex)
    {
        foreach (var compilerError in ex.CompilerErrors)
        {
            Console.WriteLine(string.Format("{0} - {1} - Line {2} Column {3} in {4}", compilerError.ErrorNumber, compilerError.ErrorText, compilerError.Line, compilerError.Column, compilerError.FileName));
        }
    }
}

看起来像下面这行：

Subject = "Comment Created"

后面少了一个逗号(，)，不是吗

Subject = "Comment Created",

Answer 3

Razor引擎在MVC世界之外有一些限制，因此，许多与它相关的东西根本不能工作。

我最近遇到了这个问题，我的“解决方案”是在应用配置中设置重定向基URL，并在运行时组合它，类似于：

var email = new CommentCreatedEmail
    {
        To = user.Email,
        From = ConfigurationManager.AppSettings["SmtpEMailFrom"],
        Subject = "Comment Created"
        Comment = comment,
        User = user
       CommentLink = ConfigurationManager.AppSettings["SiteUrl"] + "Comment/Details/"+comment.Id
    };

在你的.cshtml文件中：

@model MyApp.Models.CommentCreatedEmail
To: @Model.To
From: @Model.From
Subject: @Model.Subject

<p>
<a href="@Model.CommentLink">Comment</a>

希望它能帮上忙！
