For example, take a look at the template containing numerous references to a variable named @Order shown in the original snippet at the beginning of this article. For this template to compile and execute properly, the custom base class specified in the RazorEngineHost.DefaultBaseClass property must expose a asp net razor tutorial protected (or greater) access level “Order” property. Thus, to qualify as a base class for this template an Order property must be added to the OrderInfoTemplateBase class. Once you’ve created an instance of your custom Razor template type, simply call the .Execute() method to execute the generated code.
- The important thing to note here is that, contrary to what you may be more used to, we’re not telling the View to directly use the ViewModel.
- Seen from the browser, the HTML generated by server code is
no different than static HTML content.
- Other tools include a stack trace explorer, NuGet browser, and VCS and database support.
- The default ASP.NET MVC Razor view class exposes properties such as Model, Html, etc., that this view relies on.
- The library has a static engine accessible through Engine.Razor, but we can also create an instance of the Razor engine for use in our applications.
If you want to use model in, then you must declare the model in the view; for this you must use @model shown as below. Instead, you will see the “alert(‘You are under cross-site script injection attack’);” printed in the browser. A switch statement can insert a section into HTML based on a number of conditions.
How to use Razor View Engine in ASP.NET Core MVC
I would like to use Razor as a templating engine in a .NET console application that I’m writing in .NET Core. We’ll use this project to work with Razor views in the subsequent sections of this article. The ASPX View Engine is the legacy view engine built into ASP.NET MVC from its initial days. The Razor View Engine is more advanced and is now the default view engine of ASP.NET Core MVC. This article compares these two view engines in brief and then discusses how you can work with the Razor View Engine in ASP.NET Core MVC. Our results are exactly like the previous sample, but now we’re using our Person class to strongly-type our template.
- The code is surprisingly short, although finding the right combination of actions here is not exactly easy to discover.
- If you are writing the .dll to disk, you will need to take care over issues such as file permissions and naming, and also take care of file locks if reading the assembly back from disk.
- In the above example, we have declared var price having a value of 60 and we are using if statement which is validating price.
- Server code can create dynamic HTML content on the fly, before it is
sent to the browser.
- I would like to use Razor as a templating engine in a .NET console application that I’m writing in .NET Core.
In addition to the bundled plugins (such as those for VCS, F#, and Unity support), plugins that support Markdown, .gitignore files, and Python scripts are available. Rider boasts 2,200+ live code inspections, with automated quick-fixes to resolve detected issues individually or in bulk. Solution-wide error analysis will monitor code issues and let you know if anything goes wrong, even in files that are not currently open. An important feature of dynamic web pages is that you can determine what to
do based on conditions. It would have been awesome if Microsoft would have made Razor a standalone templating engine, and then plugged it into ASP.NET.

In fact, with a working knowledge of the Razor API, you can leverage Razor templates in any application. The Razor API exposes a powerful library for parsing, compiling, and executing templates created using the Razor syntax. With the template having been dynamically compiled and made ready for use in previous steps, we now need to merge it with the ViewModel data and render HTML markup. There is a brittleness in this code that could potentially cause problems for you. To quickly give an overview of what is happening, this step revolves around taking code defined as Razor syntax, parsing it then processing it into a raw C# equivalent. If you were to inspect this intermediary C# code, you’d see things such as calls to methods for writing strings.
