问题:

I am trying to generate emails with HTML content. this content has already gone through sanitation so I am not worried in that regard, however when I call:

Razor.Parse(template, model);

on the following Razor template:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
    <body>
        @(new System.Web.HtmlString(Model.EmailContent))
    </body>
</html>

the email that is outputted is HTMl encoded, but I need it decoded. How can I accomplish this?

回答1:

RazorEngine, like MVC's Razor View Engine, will automatically encode values written to the template. To get around this, we've introduce an interface called IEncodedString, with the default implementations being HtmlEncodedString and RawString.

To use the latter, simply make a call to the inbuilt Raw method of TemplateBase:

@Raw(Model.EmailContent)

FYI I have a fork that includes the @Html.Raw(...) syntax here:

I am using RazorEngine 3.8.2 and @Raw(Model.Content) is working perfectly fine for me.

If you have a custom base class for your templates, you can code Write method to behave similar to normal MVC template: if the output value is IHtmlString it should not encode it.

Here's the code I'm using in my TemplateBase class:

// Writes the results of expressions like: "@foo.Bar"
public virtual void Write(object value)
{
    if (value is IHtmlString)
        WriteLiteral(value);
    else
        WriteLiteral(AntiXssEncoder.HtmlEncode(value.ToString(), false));
}

// Writes literals like markup: "<p>Foo</p>"
public virtual void WriteLiteral(object value)
{
    Buffer.Append(value);
}

Built a wrapper for RazorEngine that adds in support for @Html.Raw() and @Html.Partial()

I found all of these worked with me.

@{var myHtmlString = new HtmlString(res);}
@myHtmlString


  @MvcHtmlString.Create(res)

  @Html.Raw(res)
