Welcome to View Renderer

This is an ASP.NET Core service that can render a view to string. The service is most commonly used by Emailer service.

Setup

RazorViewToStringRenderer - This service is responsible for rendering razor view(*.cshtml) to string. Service is added in the ConfigureServices method in following way:

services.AddRazorViewToStringRenderer(options => 
{
	options.ContentRoot = HostingEnvironment.ContentRootPath;
	options.EmailsFolder = "Emails";
});

• ContentRoot - this option is needed so the service knows where to look for views. It is obtainable via IWebHostEnvironment interface.
• EmailsFolder - this setting is optional. Default value is "Emails" and this is the name of the folder that should be in folder Views.

Note - The service is added as transient.

Usage

Lets say we have a user registration model that looks like this:

public class ActivationEmailModel
{
	public string ActivationLink { get; set; }
} 

Then lets say we have a RazorView looking like this:

Views/Emails/Registration.cshtml

@model ActivationEmailModel
<div>
	Thank you for registering with us please activate you account by clicking the link below
	<a href="@Model.ActivationLink">Activate</a>
</div>

First we would obtain the service by asking the service provider for it.

var viewRenderer = IServiceProvider.GetService<IViewToStringRenderer>();

Then we call the method with two parameters:

• viewName - name of the view that will be converted to its string representation
• model - model that the view will use

The method call would look like following:

var model = new ActivationEmailModel 
{
	ActivationLink = "yoursite.com/account/activate?id=abc123"
};

viewRenderer.RenderViewToStringAsync("Registration", model);
