A library for parsing Razor in an MVC app, and also if needed without relying on an MVC context. Additionally a library for exporting views as PDF files.


  1. Add a reference to this library (duh!) by either:

    a. Downloading this codebase and compiling it, or instead I recommend;

    b. Use the Nuget package by using the Nuget Package Manager in Visual Studio or running this in the package manager console:

     Install-Package Wired.Razor
  2. Create an instance of the parser:

    using Wired.Razor;
    //This can go anywhere, or preferably be injected
    var parser = new Parser();
  3. Now assuming you have a model like this:

    public class FoodModel
      public string FoodName { get; set; }
  4. And a view like this:

    @model MyApp.FoodModel
    <p>Hello, this is my view and my favourite food is @Model.FoodName</p>
  5. You can get your rendered output like this:

    //Create our model
    var model = new FoodModel
      FoodName = "Cheese"
    //Render the view
    var renderedView = parser.RenderView(viewName, model);

Easy enough right?

Something a bit more complicated

Well life is never quite that simple is it? One thing that RazorEngine needs help with is locating any layout files you have. As it has no MVC context, that means there is no View engine to tell it where to look for layouts and such. So we get around that by telling the Wired.Razor exactly what it needs. So if we have a (slightly) more advanced view like this:

@model MyApp.FoodModel
  Layout = "~/Shared/_Layout.cshtml";

Hello, this is my view and my favourite food is @Model.FoodName

We need change our call to this:

//Create our model
var model = new FoodModel
  FoodName = "Cheese"

//Set up the templates
var templates = new List<Template>
  new Template
    Name = "~/Views/Shared/_Layout.cshtml",
    Source = System.IO.File.ReadAllText(Server.MapPath("~/Views/Shared/_Layout.cshtml"))

//Render the view
var renderedView = parser.RenderView(viewName, model);

What Next?

Well that's up to you. You can use this approach to build email content for your website. Fed up of writing HTML and doing some weird things with string concatenation? Use Wired.Razor to simplify that process. And as the file it uses are Razor templates, you don't need to recompile your app when the sales director comes to you and says "Hey man, I've been talking to the guys at Initrode and they asked if we could make the emails look purple on Fridays. I told them we can do that as we're a forward thinking dynamic company. So I'm gonna need you to come in on Saturday to make this work mmkay?" Well now you just tweak your templates, tell your boss you worked all Saturday while you were really home with family | partying with friends | playing videogames.

Bonus Round!

If you do this:

parser.Debug = true;

Then you can fire up Visual Studio, press F5 and step through your views as they are parsed, just like you would for any other view in your project. Just remember to turn it off for production as it's not optimised when in debug mode. I would actually recommend doing this:

parser.Debug = true;

As this will automatically set debug on in your testing environment, but when you compile it for release mode, it'll be back to it's usual speedy self.

Didn't you say something about PDFs?

Of course I did, and here's how you do it. First you will need the Nuget package by using the Nuget Package Manager in Visual Studio or running this in the package manager console:

Install-Package Wired.RazorPdf

So there's 2 different ways here. They both essentially do the same thing but one of them relies on an MVC ControllerContext. This means it works great in your MVC app, but if you want to farm out your PDF generation to a service or a background job using something like the awesome Hangfire, then you need to be able to do everything standalone.

The benefit of using the MVC bound version is that you get the nice helpers that MVC provides you with. So things like @Html.ActionLink(...), @Url.Action(...) etc.

Using MVC

So inside an MVC action, it's simple:

public ActionResult Index()
  var generator = new MvcGenerator(ControllerContext);
  var pdf = generator.GeneratePdf(model, "PdfView");
  return new FileContentResult(pdf, "application/pdf");


Only slightly different really:

public ActionResult Index()
  var generator = new StandaloneGenerator(new Parser());
  var pdf = generator.GeneratePdf(model, Server.MapPath("~/Views/Pdf/ControllerlessPdfWithoutLayout.cshtml"));
  return new FileContentResult(pdf, "application/pdf");

The difference here is that you are giving the generator an instance of the aformentioned Wired.Razor.Parser class instead of a ControllerContext and you specify the full path to the view file. Note that you still need to pass in the templates (generator.Templates = ...) as you did above.

But I want my PDF output to look different!

We have you covered! all of the GeneratePdf methods have a second overload that lets you configure how your PDF is generated. For example, let's say you want landscape output, it's only a small change:

public ActionResult Index()
  var generator = new StandaloneGenerator(new Parser());
  var pdf = generator.GeneratePdf(
    (writer, document) =>
	model, Server.MapPath("~/Views/Pdf/ControllerlessPdfWithoutLayout.cshtml"));
  return new FileContentResult(pdf, "application/pdf");

But I want to have a different footer/header on every PDF page!

We've got you covered there too! It's pretty similar to creating a normal PDF, only a lot smaller and you need to use a special model because we want to track the page numbers.

var generator = new StandaloneGenerator(new Parser(), Server.MapPath("~"));

var model = new FooterModel
  Name = "Unicorns Rule"

var snippet = new Footer(model, Server.MapPath("~/Views/Pdf/_Footer.cshtml"), 50, 5, 5, 10);

var pdf = generator.GeneratePdf(GetModel(), Server.MapPath("~/Views/Pdf/ControllerlessPdfWithoutLayout.cshtml"));

How do I insert a new page into my PDF?

You do this in the same way you would in an iTextSharp document:

<div style="page-break-before:always">&nbsp;</div>

What Else?

So, images are almost always a huge annoyance in this situation. How does the PDF engine (iTextSharp by the way) know where to get images from? In both the MVC generator and the standalone, there are constructors that take a value for imageBasePath. That's a string containing the base path for all images. So say you had in your view something like this:

<img src="/images/next-weeks-lottery-numbers.jpg" />

Well you now need to instantiate the generator like this (in an MVC context):

var generator = new MvcGenerator(ControllerContext, , Server.MapPath("~"));

This causes your views to be rendered slightly differently, the above would become this:

<img src="c:\Users\David\Documents\projects\MyApp\images\next-weeks-lottery-numbers.jpg" />

Anything Else?

I suggest you just give it a try and see how you get on. If you discover a bug then submit an issue and I'll take a look at it. IF you fancy fixing it yourself or adding your own feature, then go right ahead and submit a pull request, I'd absolutely love that!

Good luck!
