MVC 3将View从视图传递给控制器​​

Question

每当我尝试使用模型将视图中的值传递给控制器​​时，它将在控制器中显示为null。我在项目的另一部分尝试了一些非常类似的东西，但没有遇到这个问题。为什么这会回到空？

这里是从控制器代码：

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> 

} 

型号：

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) 

写

[HttpPost] 
public ActionResult Edit(MovieReview model) 

（在该方法从审查到模型进一步将其重命名。它应该工作。

OR MovieReview.Review的别的东西

重命名属性（例如，Review1）。你不能有一个属性相同的名称，并通过模型对象（不区分大小写）

Answer 2

你一定要试试这个

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