我通过表单HttpPost将ViewModel从视图传回控制器。然而,返回的值总是NULL。
ViewModel
public class vmCompanyAddress
{
public StatelyTechAdmin.Models.Company Company { get; set; }
public StatelyTechAdmin.Models.CompanyAddress Address { get; set; }
public SelectList Counties { get; set; }
}
公司级模型
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; }
}
公司地址类模型
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(get):
// 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(POST):
[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);
}
查看(创建)

ViewBag.Title = "Create";
}

请问有人能提供建议,为什么我的返回ViewModel值是NULL,即使所有字段都填写了?
我使用Google Chrome浏览器的"Network Record"功能进行检查,所有数值都以JSON格式发送。
非常感谢。

以下是我从Google Chrome Network Monitor中看到的部分内容:
Company.Name:ABC123 Company.CreatedDate:2014/05/13 00:00:00 ....
所以它绝对是被返回的。
