Good day Tech Gurus,
l am following a tutorial by some genius, a project called sportsStore that was done using asp mvc 5 in visual studio 2013. I am following it through using visual studio 2017. Now l am getting the error mentioned on the subject. Here is what l have done
so far:

public int PageSise = 4;
public int PageSize { get; set; }//For unit tests
public ViewResult List(int page = 1){
EFProductRepository repository = new EFProductRepository();
ProductsListViewModel model = new ProductsListViewModel() {
Products = repository.Products
.OrderBy(p => p.ProductID)
.Skip((page - 1) * PageSize)
.Take(PageSize),
PagingInfo = new PagingInfo
{
CurrentPage = page,
ItemsPerPage = PageSize,
TotalItems = repository.Products.Count()
}
};
return View(model);
}
}
}
//From SportsStore.WebUI View
@using SportsStore.Domain.Entities

@{ ViewBag.Title = "Products"; }
@foreach (var p in Model.Products) {

<span class="lead"> @p.Description</span>

}

namespace SportsStore.WebUI.Models {
public class ProductsListViewModel {
public IEnumerable Products { get; set; }
public PagingInfo PagingInfo { get; set; }
}
}
{ get { return (int)Math.Ceiling((decimal)(TotalItems) / ItemsPerPage); }//THIS IS WHERE THE ERROR IS COMING FRO
Please assist, l want to display products on pages but the ERROR is coming from this section: { get { return (int)Math.Ceiling((decimal)(TotalItems) / ItemsPerPage); }, which is a section in PagingInfo class. Just
edited the post to make the code more readable and for you guys to see where my problem is.
Thank you in advance.
