Question

有模特：

public class Company
{
    public int ID { get; set; }
    public string Name { get; set; }
    public int? AddressId { get; set; }
    public virtual Address Address { get; set; }
}

public class Address
{
    public int ID { get; set; }
    public string Street { get; set; } 
}

简化的编辑视图是：

@model ChickCRM.Models.Company

@using (Html.BeginForm())
{    
    @Html.HiddenFor(model => model.ID)
    @Html.HiddenFor(model => model.AddressId)
    @Html.HiddenFor(model => model.Address.ID)    

    @Html.EditorFor(model => model.Name)
    <br />
    @Html.EditorFor(model => model.Address.Street)

    <br />
    <input type="submit" value="Save" />
}

1）我不知道如何在公司编辑方法中更新地址属性（它只是更新公司的属性，而不是Street）。我的意思是：

    [HttpPost]
    public ActionResult Edit(Company company)
    {
            db.Entry(company).State = EntityState.Modified;
            db.SaveChanges();

            return RedirectToAction("");
    }

2）我不知道如何使用子属性Address.Street的验证Include属性（如果我想使用它）

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Edit([Bind(Include = "ID,Name,AddressId,Address.Street")] Company company)
...

Answer 1

问题解决了更改子类的状态：db.Entry（company.Address）.State = EntityState.Modified;

更新EF MVC5中的子类
