[英]The current request for action 'AdminManagement' on controller type 'AdminController' is ambiguous between the following action methods
[英]The current request for action […] on controller type '…' is ambiguous between the following action methods
我無法解決此問題。
在以下操作方法之間,當前對控制器類型“ ProductController”的操作“ ListProducts”的請求是模棱兩可的:類型為Nettbutikk.Controllers.ProductController的System.Web.Mvc.ActionResult ListProducts(System.Nullable`1 [System.Int32]) Nettbutikk.Controllers.ProductController類型的.Web.Mvc.ActionResult ListProducts(Int32,System.String)
有人可以幫助我嗎?
內容:
public List<Product> getAll(int id, string something)
{
var db = new DatabaseContext();
List<Product> allProducts = new List<Product>();
var products = db.Products.Where(p => p.SubCategoriesId == id).ToList();
foreach (var p in products)
{
var product = new Product()
{
itemnumber = p.Id,
name = p.Name,
description = p.Description,
price = p.Price,
volum = p.Volum,
producer = p.Producers.Name,
pricePerLitre = pricePerLitre(p.Price, p.Volum),
category = p.SubCategories.Categories.Name,
subCategory = p.SubCategories.Name,
country = p.Countries.Name
};
allProducts.Add(product);
}
return allProducts;
}
控制器:
public ActionResult ListProducts(int? id)
{
var db = new DBProduct();
List<Product> listOfProducts;
listOfProducts = db.getAll(id);
return View(listOfProducts);
}
public ActionResult ListProducts(int id, string something)
{
var db = new DBProduct();
List<Product> listOfProducts;
listOfProducts = db.getAll(id,tull);
return View(listOfProducts);
}
和視圖:
<a href='@Url.Action("ListProducts", "Product", new { id = 1, tull = "" })'>sub category</a>
這是因為您有兩個重載的操作,這些操作導致路由混亂。 在您的示例中,您認為
<a href='@Url.Action("ListProducts", "Product", new { id = 1, tull = "" })'>sub category</a>
將轉到ListProducts(int id,字符串的東西)。 沒有! 這是錯誤的假設。...URL類似於yourdomain / 1,因為某些內容為空。...這似乎是第一個動作。
因此,當某個變量為空時,這兩種操作方法會使路由引擎感到困惑。
因此,將名稱更改為其他名稱
public ActionResult ListProductsbyId(int? id)
{
var db = new DBProduct();
List<Product> listOfProducts;
listOfProducts = db.getAll(id);
return View(listOfProducts);
}
public ActionResult ListProductsByIdAndTull (int id, string tull)
{
var db = new DBProduct();
List<Product> listOfProducts;
listOfProducts = db.getAll(id,tull);
return View(listOfProducts);
}
或只是一個動作
public ActionResult ListProducts(int? id, string tull)
{
var db = new DBProduct();
List<Product> listOfProducts;
if(String.IsNullOrEmpty(tull)
{
listOfProducts = db.getAll(id);
}
else
{
listOfProducts = db.getAll(id,tull);
}
return View(listOfProducts);
}
