值不能为null或为空。参数名称：Url.Content中的contentPath错误

Question

我收到此错误：值不能为null或为空。参数名称：contentPath。我只是想用＆＃34; Url.Content＆＃34;来显示图像。在索引视图中。在调试中进入此页面时，它突破了上述错误：对此有任何帮助将不胜感激。

控制器：

// GET: Customers/Create
        public ActionResult Create()
        {
            return View();
        }

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "CustomerID,DiscountLevelID,LoyaltyLevelID,CustomerCompanyName,CustomerName,CustomerSurname,CustomerGUID,CustomerStatus,CustomerAddress,CustomerTel,CustomerCel,CustomerNumber,CustomerContact,CustomerLogo,CustomerLogoPath,LastStoreCustomerSyncID")] Customer customer, HttpPostedFileBase file)
{
    if (ModelState.IsValid)
    {
        if (file != null)
        {
            string ImageName = System.IO.Path.GetFileName(file.FileName);
            string physicalPath = Server.MapPath("~/Images/");
            if (!Directory.Exists(physicalPath))
                Directory.CreateDirectory(physicalPath);
            string physicalFullPath = Path.Combine(physicalPath, ImageName);
            file.SaveAs(physicalFullPath);

            customer.CustomerLogo = ImageName;
            customer.CustomerLogoPath = physicalFullPath;
            db.Customers.Add(customer);
            db.SaveChanges();
        }
        return RedirectToAction("Index");

    }
    return View(customer);
}
