我通過窗體HttpPost從視圖傳回ViewModel到控制器。但是，返回的值始終爲NULL。MVC視圖ViewModel HttpPost返回值始終爲NULL
視圖模型
public class vmCompanyAddress
{
public StatelyTechAdmin.Models.Company Company { get; set; }
public StatelyTechAdmin.Models.CompanyAddress Address { get; set; }
public SelectList Counties { get; set; }
}
公司類模型
public class Company
{
[Key]
public virtual long CompanyId { get; set; }
[Required]
[Display(Name = "Company Name")]
public virtual string Name { get; set; }
public virtual DateTime CreatedDate { get; set; }
public virtual IEnumerable<CompanyAddress> CompanyAddresses { get; set; }
}
公司地址類模型
public class CompanyAddress
{
[Key]
public virtual long CompanyAddressId { get; set; }
[Required]
public virtual long CompanyId { get; set; }
[ForeignKey("CompanyId")]
public virtual Company Company { get; set; }
[Required]
public virtual int CopmanyAddressTypeId { get; set; }
[ForeignKey("CopmanyAddressTypeId")]
public virtual CompanyAddressType CompanyAddressType { get; set; }
[Display(Name = "Address 1")]
public virtual string Address1 { get; set; }
[Display(Name = "Address 2")]
public virtual string Address2 {get; set; }
[Display(Name = "Town")]
public virtual string Town { get; set; }
[Display(Name = "City")]
public virtual string City { get; set; }
[Required]
public virtual long CountyId { get; set; }
[ForeignKey("CountyId")]
[Display(Name = "County")]
public virtual County County { get; set; }
[Required]
[Display(Name = "Postal Code")]
public virtual string PostalCode { get; set; }
public virtual DateTime CreatedDate { get; set; }
}
控制器（獲得）：
// GET: /Company/Create
public ActionResult Create()
{
vmCompanyAddress vm = new vmCompanyAddress();
vm.Counties = new SelectList(db.County, "CountyId", "Name", -1);
//vm.Address = new CompanyAddress();
//vm.Company = new Company();
return View(vm);
}
控制器（後）：
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(vmCompanyAddress company)
{
if (ModelState.IsValid)
{
db.Companies.Add(company.Company);
//Amend Address Company & Address Type before save to DB
company.Address.CompanyId = company.Company.CompanyId;
company.Address.CopmanyAddressTypeId = 1;
db.CompanyAddress.Add(company.Address);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(company);
}
視圖（創建）
@model StatelyTechAdmin.ViewModels.vmCompanyAddress
@{
ViewBag.Title = "Create";
}
<h2>Create</h2>
@using (Html.BeginForm()) {
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
<fieldset>
<legend>Company</legend>
<div class="editor-label">
@Html.LabelFor(model => model.Company.Name)

任何人都可以請提供任何意見，以爲什麼當所有字段被填充時，我的返回ViewModel值爲NULL？
我已使用網絡記錄功能在Google Chrome瀏覽器中進行了檢查，並且所有值均以JSON格式發回。
非常感謝。

這裏有什麼我可以從谷歌Chrome網絡看到部分監控
Company.Name:ABC123 Company.CreatedDate：2014年5月13日00:00:00 ....
所以肯定是被退回了。
夠搞怪，有人已經有過類似的問題，與回發 「Company.Name」。對於funsies，請嘗試刪除該字段並查看它是否仍將所有內容都回傳爲空。 http://stackoverflow.com/questions/780026/asp-net-mvc-model-binding-returning-null-values –
CompanyAddressTypeId拼寫錯誤。另外，嘗試像這樣定義你的表單 - Html.BeginForm（「yourControllerNameHere」，「Create」，FormMethod.Post） – JB06
謝謝@ErikElkins然而，從我的View中刪除Company.Name並沒有什麼區別。一切仍然回傳爲NULL。 – RobHurd
