我正在使用Razor引擎解析电子邮件模板的主体。是否可以定义布局并包含其他.cshtml文件？例如，一个普通的页眉和页脚。

你可以轻松地用Razor做很多事情；然而，那个特殊的项目似乎把你能做的很多剃须刀引擎的东西都抽象掉了（这是好的也是坏的）。在您的情况下，听起来您最好实现自己的Razor解决方案（实际上没有那么糟糕），然后您可以让您的模板很容易地抛出异常或引入其他内容

比如,；滚动您自己的解决方案允许您为razor模板创建一个基类，它可以通过调用其他模板公开拉入“部分视图”的能力。此外，如果某些属性为null，则可以执行模型检查并引发异常

在这两篇文章的帮助下，我得到了通用模板和布局：

这是我的解决方案：

解决方案1：布局

public class MailClient
    {
        public MailClient()
        {
            SmtpClient = new SmtpClient(MailConfiguration.Host)
            {
                Port = MailConfiguration.Port,
                Credentials = new NetworkCredential
                {
                    UserName = MailConfiguration.UserName,
                    Password = MailConfiguration.Password
                }
            };
        }

        public SmtpClient SmtpClient { get; }
    }

用于设置_布局

@{
    _Layout = "Layout.cshtml";
    ViewBag.Title = Model.Title;
 }

页脚

@section Footer 
{
   @RenderPart("Footer.cshtml")
}

@section Footer 
{
   @Include("Footer.cshtml")
}

public class TemplateResolver : ITemplateResolver
{
    public string Resolve(string name)
    {
        if (name == null)
        {
            throw new ArgumentNullException("name");
        }

        string path = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase, "Templates", name);
        return File.ReadAllText(path, System.Text.Encoding.Default);
    }
}

Layout.cshtml

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html>
    <head>
    </head>
    <body>
        <div id="content">
            @RenderBody()
        </div> 
        @if (IsSectionDefined("Footer"))
        { 
            <div id="footer">
                @RenderSection("Footer")
            </div>
        }
    </body> 
</html>

@using RazorEngine.Templating
@inherits TemplateBase<myviewmodel>

<h1>Hello People</h1>
<p>@Model</p>

解析器

@section Footer 
{
   @RenderPart("Footer.cshtml")
}

@section Footer 
{
   @Include("Footer.cshtml")
}

public class TemplateResolver : ITemplateResolver
{
    public string Resolve(string name)
    {
        if (name == null)
        {
            throw new ArgumentNullException("name");
        }

        string path = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase, "Templates", name);
        return File.ReadAllText(path, System.Text.Encoding.Default);
    }
}

配置

TemplateServiceConfiguration templateConfig = new TemplateServiceConfiguration
{
     Resolver = new TemplateResolver()
};
Razor.SetTemplateService(new TemplateService(templateConfig));

松饼人更新指定模板并呈现字符串

var templateResolver = Razor.Resolve("Registration.cshtml"); return templateResolver.Run(new ExecuteContext());
另外，我和这个链接上的其他人在使用
\u布局
时遇到了问题，而
布局
工作正常

“_Layout”是旧语法。在未来的版本中，它被更新为“布局”
使用RazorEngine实现布局的最简单方法是替换布局的@RenderBody（）中模板返回的内容：

var finalHtml = layout.Replace(@"@RenderBody()", templateHtml);
例如：

<html> <body style="margin: 0; padding: 0;"> <div style="width:100%; display:block; float:left; height:100%;"> <table cellpadding="0" cellspacing="0" border="0" align="center" width="100%"> <tr> <td width="37" style="background-color: #ffffff;"></td> <td width="200" style="background-color: #ffffff"> <a href="@Url("")">Send Mail Logo</a> </td> <td style="background-color: #ffffff;">   </td> <td width="126" style="background-color: #ffffff;"> <img src="@Url("Images/mail/social-media.png")" alt="" width="126" height="73" border="0" usemap="#Map" /> </td> </tr> </table> <table cellpadding="0" cellspacing="0" border="0" align="center" width="100%"> <tr height="7"> <td style="background-color: #ffffff;" colspan="3"></td> </tr> <tr height="54"> <td colspan="3"></td> </tr> <tr> <td width="37"> </td> <td style="font-family: Myriad, 'Helvetica Neue',Arial,Helvetica,sans-serif; font-size: 11pt; color: #6b6c6f; line-height: 24px;"> {{BODY}} </td> <td width="37"> </td> </tr> <tr height="55"> <td style="line-height: 0;" colspan="3"> </td> </tr> <tr height="11"> <td background="@Url("/Images/mail/dotted-line.png")" colspan="3" style="line-height: 0;"> </td> </tr> </table> </div> <map name="Map" id="Map"> <area shape="rect" coords="28,29,51,51" href="#" alt="Twitter" /> <area shape="rect" coords="56,28,78,52" href="#" alt="Google+" /> <area shape="rect" coords="84,28,104,51" href="#" alt="LinkedIn" /> </map> </body> </html>

在MailSerder类中实现您的方法，并在存储库或控制器中调用MailSerder方法

Create public class MailSender : IMailSender { public MailSender() { } public void SendConfirmEmail(string emailId, Guid userId) { var confirmEmail = new ConfirmEmail { UserId = userId }; ConfirmEmail(emailId, MailResource.YourRegistration, confirmEmail); } private void ConfirmEmail(string recipient,string subject,ConfirmEmail model) { var key = Guid.NewGuid(); var mail = new Mail<ConfirmEmail>("ConfirmEmail", model); mail.ViewBag.AddValue("Recipient", recipient); var sentMail = mail.Send(key, recipient, subject); } }

创建公共类mailssender:IMailSender { 公共邮件发送者（） { } public void SendConfirmEmail（字符串emailId，Guid userId） { var confirmEmail=新的confirmEmail { UserId=UserId }; 确认邮件（emailId，MailResource.YourRegistration，确认邮件）； } 私有无效确认邮件（字符串收件人、字符串主题、确认邮件模型） { var key=Guid.NewGuid（）； var mail=新邮件（“确认邮件”，型号）； mail.ViewBag.AddValue（“收件人”，收件人）； var sentMail=mail.Send（键、收件人、主题）； } }
我试图在上面的MS博客中实现该解决方案，但我一直收到stackoverflow异常。我已经花了一整天的时间在这上面了。我可以给你寄一份快速的申请表。我把它拼凑起来，你就知道了。它已经拼凑好了，但你肯定会明白的。应用程序库是RazorEngineConsoleApplication\bin\Debug，因此我将模板复制到其中。为了坚持我发布的示例，使用@Include（“Footer.cshtml”，Model）代替@RendarPart，它将使用模板解析器。RendarPart扩展不需要
ITemplateResolver
是票据。没有别的办法。最后编写了一个自定义路径处理程序，以消除搜索视图时的任何怪癖。
