ASP.NET Core - acessing object from razor in code behind

I'm new to ASP.NET Core, so I'm still trying to understand it.

I was trying to access an object from code behind. Is it possible? I have been trying and searching for hours and I have yet to understand it. I'll leave some of what I've tried bellow, which apparently isn't working. If I could get some insight on this I'd very much appreciate it.

In classic ASP.NET I always to the id approach from code behind to the client side. But now I've been asked to try a different approach. In this case, a loop. How can I do this? I've also been reading the microsoft documentation but I still can't understand this. I'd appreciate some help.

Here's a spinnet of what I tried:

// The controller
public class HomeController : Controller
    {
        public GetInfo GetInfo { get; set; }
        public IActionResult Offers()
        {

            GetInfo = new GetInfo();

            GetInfo.GetOffers();

            return View();
        }
    }


// The GetInfo class which gets data from a JSON file
public class GetInfo
    {
        public Offer.RootObject Offers { get; set; }

        public void GetOffers()
        {
            var client = new RestClient("whatever.com");
            // client.Authenticator = new HttpBasicAuthenticator(username, password);

            var request = new RestRequest("Home/GetOffersJson", Method.GET);
            IRestResponse response = client.Execute(request);
            var content = response.Content;

            var obj = JsonConvert.DeserializeObject<Offer.RootObject>(content);

            Offers = new Offer.RootObject
            {
                total = obj.total,
                data = obj.data
            };


        }
    }

// The View file, where I'm trying to access the object from c#, which supposedly is 'loaded'
@model HostBookingEngine_HHS.Models.GetInfo;
@{
    ViewData["Title"] = "Offers";


}

    @foreach (var item in Model.Offers.data)
    {
        <span asp-validation-for="@item.TextTitle"></span>

    }

Thanks, in advance.

asp.net core view has four over loading these are

public virtual ViewResult View();
public virtual ViewResult View(string viewName, object model);
public virtual ViewResult View(object model);
public virtual ViewResult View(string viewName);

ASP.NET Core can use all of these with exact parameter You can pass your model object using Public Virtual ViewResult View(object model);

You need to pass your model object like this 

return View(GetInfo);

which actually access your parameter object 

@model HostBookingEngine_HHS.Models.GetInfo;

Also there are several method of passing data to view

Like ViewBag,ViewData which also grab the value in each request.

To have Offers available on view, you have to pass model to a view as an argument to View() method. So in your case you have to make your action look like:

public IActionResult Offers()
{
    GetInfo = new GetInfo();
    GetInfo.GetOffers();
    return View(GetInfo);
}
