How to render razor view as string in .net core web api? - asp.net-core-2.0

Question

I have .net core web api application. I need to send out the email using razor view. I cannot get razor view as string to send out the email.
I get the exception at Engine.Razor.RunCompile(razorView, "templateKey" + DateTime.Now.Ticks, null, model);
Below is my code.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using MyProject.Api.Models;
using RazorEngine;
using RazorEngine.Templating;
namespace MyProject.Api.Controllers
{
[Route("api/[controller]")]
[ApiController]
public class AppointmentBookingController : ControllerBase
{
private readonly IHostingEnvironment _hostingEnvironment;
public AppointmentBookingController(IHostingEnvironment hostingEnvironment)
{
_hostingEnvironment = hostingEnvironment;
}
[HttpGet]
[Route("GetViewAsString")]
public string GetViewAsString()
{
string webRootPath = _hostingEnvironment.WebRootPath;
string contentRootPath = _hostingEnvironment.ContentRootPath;
BaseHttpRequestModel model = new BaseHttpRequestModel
{
LanguageID = "ABC"
};
string razorView = System.IO.File.ReadAllText(contentRootPath + #"\Views\EmailTemplates\Test.cshtml");
Engine.Razor.RunCompile(razorView, "templateKey" + DateTime.Now.Ticks, null, model);
return razorView;
}
}
}

You need to supply the model type instead of passing null when using a strongly typed model. You pass null in when using anonymous or dynamic types. Also return the output of RunCompile:
...
var result = Engine.Razor.RunCompile(razorView, "templateKey" + DateTime.Now.Ticks, model.GetType(), model);
return result;
