不一致的可访问性：字段类型'FashionWorldApp.Domain.Abstract.IOrderProcessor'比字段'

Question

更容易访问。从下面的代码中，我一直参考私有IOrderProcessor orderProcessor;来解决此错误不一致的可访问性问题。我已经将私人更改为公开，但错误仍然存​​在。有人可以帮我吗？

namespace FashionWorldApp.WebUI.Controllers 
{ 
public class CartController : Controller { 
    private IProductRepository repository; 
    private IOrderProcessor orderProcessor; 

    public CartController(IProductRepository repo, IOrderProcessor proc) 
    { 
     repository = repo; 
     orderProcessor = proc; 
    } 

    public ViewResult Index(Cart cart, string returnUrl) 
    { 
     return View(new CartIndexViewModel 
     { 
      Cart = cart, 
      ReturnUrl = returnUrl 
     }); 
    } 

    public PartialViewResult Summary(Cart cart) 
    { 
     return PartialView(cart); 
    } 

    [HttpPost] 
public ViewResult Checkout(Cart cart, ShippingDetails shippingDetails) 
    { 
     if (cart.Lines.Count() == 0) 
     { 
      ModelState.AddModelError("", "Sorry, your cart is empty!"); 
     } 

     if (ModelState.IsValid) 
     { 
      orderProcessor.ProcessOrder(cart, shippingDetails); 
      cart.Clear(); 
      return View("Completed"); 
     } 
     else 
     { 
      return View(shippingDetails); 
     } 
    } 

    public ViewResult Checkout() 
    { 
     return View(new ShippingDetails()); 
    } 
    public RedirectToRouteResult AddToCart 
      (Cart cart, int productId, string returnUrl) 
    { 
     Product product = repository.Products 
      .FirstOrDefault(p => p.ProductID == productId); 

     if (product != null) 
     { 
      cart.AddItem(product, 1); 
     } 
     return RedirectToAction("Index", new { returnUrl }); 
    } 

public RedirectToRouteResult RemoveFromCart 
     (Cart cart, int productId, string returnUrl) 
    { 
     Product product = repository.Products 
      .FirstOrDefault(p => p.ProductID == productId); 

     if (product != null) 
     { 
      cart.RemoveLine(product); 
     } 
     return RedirectToAction("Index", new { returnUrl }); 
    } 
} 
}

将IProductRepository接口更改为public。你有一个接受IProductRepository作为参数的公共构造函数，你需要保证外部调用可以看到它。
