Question

我正在研究MVC asp.net。

这是我的控制器动作：

public ActionResult ingredientEdit(int id) {
    ProductFormulation productFormulation = db.ProductFormulation.Single(m => m.ID == id);
    return View(productFormulation);
}

//
// POST: /Admin/Edit/5

[HttpPost]
public ActionResult ingredientEdit(ProductFormulation productFormulation) {
    productFormulation.CreatedBy = "Admin";
    productFormulation.CreatedOn = DateTime.Now;
    productFormulation.ModifiedBy = "Admin";
    productFormulation.ModifiedOn = DateTime.Now;
    productFormulation.IsDeleted = false;
    productFormulation.UserIP = Request.ServerVariables["REMOTE_ADDR"];
    if (ModelState.IsValid) {
        db.ProductFormulation.Attach(productFormulation);
        db.ObjectStateManager.ChangeObjectState(productFormulation, EntityState.Modified);
        db.SaveChanges();
        **return RedirectToAction("ingredientIndex");**
    }
    return View(productFormulation);
}

我想将id传递给ingredientIndex动作。我怎么能这样做？

我想使用来自另一个页面的id 公共ActionResult ingredientEdit（int id）。实际上我在第二次行动中没有id，请告诉我该怎么做。

Answer 1

return RedirectToAction("IngredientIndex", new { id = id });

更新

首先我将IngredientIndex和IngredientEdit重命名为Index and Edit并将它们放在IngredientsController中，而不是AdminController，如果需要，可以有一个名为Admin的区域。

//
// GET: /Admin/Ingredients/Edit/5

public ActionResult Edit(int id)
{
    // Pass content to view.
    return View(yourObjectOrViewModel);
}

//
// POST: /Admin/Ingredients/Edit/5

[HttpPost]
public ActionResult Edit(int id, ProductFormulation productFormulation)
{
    if(ModelState.IsValid()) {
        // Do stuff here, like saving to database.
        return RedirectToAction("Index", new { id = id });
    }

    // Not valid, show content again.
    return View(yourObjectOrViewModel)
}

Answer 2

为什么不这样做？

return RedirectToAction("ingredientIndex?Id=" + id);

Answer 3

尝试这种方式：

return RedirectToAction("IngredientIndex", new { id = productFormulation.id });

如何在RedirectToAction中传递参数？
