 public ActionResult ShowProducts(string productName)
    {

        ProductRepository blProduct = new ProductRepository();
        var src = blProduct.Where(p => p.Url.Trim() == productName.Trim());
        if (src.Any())
        {
            return View(src.Single());
        }
        else
        {
            return RedirectToAction("Index");
        }

    }

thank you for your attention, i have a product in my main page, when i push On Details product button i want Redirect in this View model(ShowProduct.csHtml) and thats work! and i wanna see my Product Details , i use IEnumerable cause i wanna use forech for showing my another product (Releated Product) on Bottom of my ShowProduct Page but when i run my project and pushed on details product bottun i redirected in Showproduct View Model but this error come up for me :

The model item passed into the dictionary is of type 'System.Data.Entity.DynamicProxies.Product_9F73B4E1D7A93B6E9A923F87D780EE891805309BEF7B2609BEB9BC3DE1B25A33', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[GymInternetShop.Models.DomainModels.Product]'.

  • Why you're using `Single` if you want to iterate `IEnumerable`? Just use `ToList()` after `Where` and you will get `IEnumerable` collection from the model. – Tetsuya Yamamoto Jan 24 '19 at 09:13

  • Try return View(src.Select(s=>s).First()). You are not returning IEnumerable rather EF's dynamic proxies. If you should return a List of IEnumerable, read here https://stackoverflow.com/questions/3628425/ienumerable-vs-list-what-to-use-how-do-they-work – curious.netter Jan 24 '19 at 09:18

If you want to show all your products, why are you only passing src.Single() ?

Your view is also expecting an IEnumerable, but only getting a single.

I'd change 

var src = blProduct.Where(p => p.Url.Trim() == productName.Trim());

to

List<Product> src = blProduct.Where(p => p.Url.Trim() == productName.Trim()).ToList();

and pass it into the view:

if (src.Any())
        {
            return View(src);
        }
