Question

主要的RegisterModel调用嵌套的HomeAddress和MailAddress模型。

public class RegisterModel
{
   Public string FirstName {get; set;}
   Public string LastName  {get; set;}
   Public HomeAddressModel homeAddress {get; set;}
   Public MailAddressModel mailAddress {get; set;}
}

public class HomeAddressModel
{
    Public string Street1 {get; set;}
    Public string Street2  {get; set;}
    Public string State {get; set;}
    Public string City {get; set;}
}

public class MailAddressModel
{
    Public string Street1 {get; set;}
    Public string Street2  {get; set;}
    Public string State {get; set;}
    Public string City {get; set;}
}

地址的部分视图

@model MyNamespace.Models.???
@{
    Layout = "~/Views/_Layout.cshtml";
}
 <div id="Address">
   //Street1
   //Street2
   //State
   //City
 </div>

如何定义我的Parital视图，以便我可以在运行时使用HomeAddressModel或MailAddressModel绑定它。

我的主要注册视图

@model MyNamespace.Models.RegisterModel
@{
     Layout = "~/Views/_Layout.cshtml";
 }
@using (Html.BeginForm(null, null, FormMethod.Post, new { id = "myForm" }))
{
  <div id="form">
    @Html.TextBoxFor("FirstName");
    @Html.TextBoxFor("LastName");
   //Render Partial View for HomeAddress.
   //Will provide a checkbox if Mailing Address is different.
   //Render Partial View for MailAddress.
  </div>
}

public ActionResult Register()
{  
    var model = new RegsiterModel();
    return View(model);
}

[HttpPost]
public ActionResult Register(RegisterModel model, 
                            HomeAddressModel  homeAddress, 
                            MailAddressModel mailingAddress)
{
       //Do Something with different Addresses
       return View();
}

这个问题有5个部分： -

RegisterModel类是否正确创建？这是他们的方式我们可以筑巢吗？
我们是否应该为Address和2个不同的属性提供单个类两个地址？像地址回家{get; set;}和地址邮件{get; set;}。如果是，那么如何实现下一步。
如何为地址创建局部视图？在两种情况下都是如此使用单独的HomeAddres类和MailAddress类。或使用单个Address类。
如何使用这两种方法在主寄存器视图中声明partialView 如上所述。
如何确保在[HttpPost] Action Method中我们可以阅读所有内容值，即RegisterModel值是绑定的，以及各个地址也是绑定的。

Answer 1

有一个地址模型，如

public class AddressModel
{
    Public string Street1 {get; set;}
    Public string Street2  {get; set;}
    Public string State {get; set;}
    Public string City {get; set;}
}

在Views / Shared / EditorTemplates / AddressModel.cshtml中为它制作局部视图

@model MyNamespace.Models.AddressModel
<div id="Address">
   Html.TextBoxFor(m => m.Street1)
   //Street2
   //State
   //City
</div>

现在，如果您有视图模型

public class RegisterModel
{
   Public string FirstName {get; set;}
   Public string LastName  {get; set;}
   Public AddressModel HomeAddress {get; set;}
   Public AddressModel MailAddress {get; set;}
}

简单地为每个地址渲染部分视图，如下所示

<div id="form">
    @Html.TextBoxFor(m => m.FirstName);
    @Html.TextBoxFor(m => m.LastName);
    @Html.EditorFor(m => m.HomeAddress) // !! -> this will render AdressModel.cshtml as a partial view, and will pass HomeAdress to it
   //Will provide a checkbox if Mailing Address is different.
    @Html.EditorFor(m => m.MailAddress)
</div>

如果您需要更多逻辑（视图的附加参数或类似内容），您可以选择将对EditorFor的调用包装到您自己的帮助器方法中

在HttpPost方法中使用此

[HttpPost]
public ActionResult Register(RegisterModel model)
{
}

并且地址将绑定到RegisterModel的属性。

一个强类型的局部视图，它在运行时动态模型绑定到2个不同的模型类
