型號是空的HttpPost

這其中有我百思不得其解完全...型號是空的HttpPost

我有一個非常簡單的輸入模型，有三點的屬性，像這樣：

public class SystemInputModel 
{ 
    public string Name; 
    public string Performance; 
    public string Description; 
}

在我的控制器：

public ViewResult AddSystem() 
{ 
    return View(new SystemInputModel()); 
} 


[HttpPost] 
public ActionResult AddSystem(SystemInputModel model) 
{ 
    if (ModelState.IsValid) 
    { 
     var system = new OasisSystem 
     { 
      Name = model.Name, 
      Description = model.Description, 
      Performance = model.Performance 
     }; 
     return Json(repository.AddSystem(system)); 
    } 
    return Json(new {success = false, message = "Internal error"}); 
}

的視圖：

<h2>Add System</h2> 

@using (Html.BeginForm()) 
{ 
    @Html.ValidationSummary(true) 
    <label>Name</label> 
    @Html.EditorFor(m => m.Name) 
    <br /> 
    <label>Description</label> 
    @Html.EditorFor(m => m.Description) 
    <br /> 
    <label>Performance</label> 
    @Html.EditorFor(m => m.Performance) 
    <br /> 

    <input type="submit" /> 
}

我填寫表單並點擊提交。我已經看過了原郵政提琴手：

Name=foo&Description=bar&Performance=yes

然而，正在傳遞到我的HttpPost控制器方法模型對所有三個屬性的空值。如果我將其從模型對象更改爲FormCollection，則可以看到傳入的三個屬性。

爲什麼不將已發佈的字段映射到我的模型對象？

默認的MVC 3模型聯編程序需要您的模型的屬性。

如果你改變你的模型如下：

public class SystemInputModel 
{ 
    public string Name { get; set; } 
    public string Performance { get; set; } 
    public string Description { get; set; } 
}

一切都會好起來。
