MVC 3將View從視圖傳遞給控制器​​

Question

每當我嘗試使用模型將視圖中的值傳遞給控制器​​時，它將在控制器中顯示爲null。我在項目的另一部分嘗試了一些非常類似的東西，但沒有遇到這個問題。爲什麼這會回到空？

這裏是從控制器代碼：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.Mvc; 
using MovieProject2.Models; 

namespace MovieProject2.Controllers 
{ 

public class ReviewsController : Controller 
{ 
public ActionResult Edit(int id = -1) 
{ 
    if (id < 0) 
    return HttpNotFound(); 
    MovieReview review = MovieADO.getReviewByID(id); 
    return View(review); 
} 

[HttpPost] 
public ActionResult Edit(MovieReview review) 
{ 
    if (review == null) return HttpNotFound(); 
    return View(review); 
} 
} 

查看：

@model MovieProject2.Models.MovieReview 

@{ 
    ViewBag.Title = "Edit Review"; 
} 

@{ //Not null here 
    if(@Model != null) {<h2>Edit Review for @Model.MovieReviewed.Title</h2> 
    <h4>Reviewed by @Model.Reviewer.Username</h4>} 
               else{<h2>Not Found</h2> 
} 
} 

@using (Html.BeginForm()) 
{ 
    Html.ValidationSummary(true); 
    <fieldset> 
     <div class="editor-label"> 
      @Html.LabelFor(itemModel => Model.Rating) 
     </div> 
     <div class="editor-label"> 
      @Html.EditorFor(itemModel => Model.Rating) 
      @Html.ValidationMessageFor(itemModel => Model.Rating) 
     </div> 
     <div class="editor-label"> 
      @Html.LabelFor(itemModel => Model.Review) 
     </div> 
     <div class="editor-label"> 
      @Html.EditorFor(itemModel => Model.Review) 
      @Html.ValidationMessageFor(itemModel => Model.Review) 
     </div> 
     <p> 
      <input type="submit" value="Change" /> 
     </p> 
    </fieldset> 

} 

型號：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 

namespace MovieProject2.Models 
{ 
    public class MovieReview 
    { 
     public int ReviewID { get; set; } 
     public Movie MovieReviewed { get; set; } 
     public User Reviewer { get; set; } 
     public int Rating { get; set; } 
     public string Review { get; set; } 
     public DateTime DateReviewed { get; set; } 

     public MovieReview() { } 
    } 
} 

Answer 1

而不是

[HttpPost] 
public ActionResult Edit(MovieReview review) 

寫

[HttpPost] 
public ActionResult Edit(MovieReview model) 

（在該方法從審查到模型進一步將其重命名。它應該工作。

OR MovieReview.Review的別的東西

重命名屬性（例如，Review1）。你不能有一個屬性相同的名稱，並通過模型對象（不區分大小寫）

Answer 2

你一定要試試這個

@using (Html.BeginForm("Action methodName","controllerName"))
