Razor View引用的调试模型

ASP.Net MVC和Razor Pages中的新手。Razor View引用的调试模型

我有一个Razor视图与参考模型中声明之上：

@model TestApplication.Models.Registration

我怎么能调试模式？我试着在模型中设置断点，但是在调试时，断点没有被击中。

代码如下：

Register.cshtml

@model TestApplication.Models.Registration 
@{ 
    string labelClass = "ctrl-label col-sm-4", 
     controlSize = "col-sm-8"; 
} 

<div class="row"> 
    <div class="col-md-7 col-md-offset-2"> 
     <h2>@TestApplication.Resources.General.Register</h2> 
     @using (Html.BeginForm("Register", "Account", FormMethod.Post, new{role = "form", @class = "form-horizontal" })) 
     { 
      <div class="form-group"> 
       <h3 class="@labelClass"> 
        <small>@TestApplication.Resources.General.CreateAccount</small></h3> 
      </div> 

      <hr /> 

      <div class="form-group @Html.ValidationErrorFor(m => m.EmailAddress, "has-error has-feedback")"> 
       @Html.LabelFor(p => p.EmailAddress, new { @class = labelClass }) 
       <div class="@controlSize"> 
        @Html.FormTextBoxFor(p => p.EmailAddress, new { @class = "form-control" }) 
        @if (!Html.IsValid(m => m.EmailAddress)) 
        { 
         <span class="glyphicon glyphicon-remove form-control-feedback"></span> 
        } 
        <span class="hint">@TestApplication.Resources.Forms.RegisterHintEmailAddress</span> 
        @Html.ValidationMessageFor(m => m.EmailAddress, null, new { @class = "help-block" }) 
       </div> 
      </div> 

      <div class="form-group @Html.ValidationErrorFor(m => m.Username, "has-error has-feedback")"> 
       @Html.LabelFor(p => p.Username, new { @class = labelClass }) 
       <div class="@controlSize"> 
        @Html.FormTextBoxFor(p => p.Username, new { @class = "form-control" }) 
        @if (!Html.IsValid(m => m.Username)) 
        { 
         <span class="glyphicon glyphicon-remove form-control-feedback"></span> 
        } 
        @Html.ValidationMessageFor(m => m.Username, null, new { @class = "help-block" }) 
       </div> 
      </div> 

      <div class="form-group"> 
       <label class="@labelClass">@TestApplication.Resources.Forms.RegisterLabelStartService</label> 
       <div class="@controlSize"> 

       @* I AM GETTING AN ERROR ON THIS LINE... *@ 
       @*@foreach(var m in Model.Services) 
       { 
        <div class="radio"> 
         <label> 
          @Html.RadioButtonFor(p => p.StartServiceId, m.Id) 
          @m.DisplayName 
         </label> 
        </div> 
       }*@ 
       </div> 
      </div> 
     } 
    </div> 
</div>

Registration.cs

using System.Linq; 
using System.Web; 
using System.Web.Mvc; 
using System.Web.Security; 
using System.Globalization; 
using System.ComponentModel.DataAnnotations; 
using DataAnnotationsExtensions; 
using TestApplication.Resources; 

namespace TestApplication.Models 
{ 
    public class Registration 
    { 
     [Email(ErrorMessageResourceName = "InvalidEmail", ErrorMessageResourceType = typeof(ErrorMessages))] 
     [Required(ErrorMessageResourceName = "RequiredEmailAddress", ErrorMessageResourceType = typeof(ErrorMessages))] 
     [HtmlAttribute("placeholder", "PlaceholderEmailAddress", ResourceType = typeof(Forms))] 
     [Display(Name = "RegisterLabelEmailAddress", ResourceType = typeof(Forms))] 
     public string EmailAddress { get; set; } 

     [Email(ErrorMessageResourceName = "InvalidUsername", ErrorMessageResourceType = typeof(ErrorMessages))] 
     [Required(ErrorMessageResourceName = "RequiredUsername", ErrorMessageResourceType = typeof(ErrorMessages))] 
     [HtmlAttribute("placeholder", "PlaceholderUsername", ResourceType = typeof(Forms))] 
     [Display(Name = "RegisterLabelUsername", ResourceType = typeof(Forms))] 
     [CustomValidation(typeof(Registration), "CheckIfUserExists")] 
     public string Username { get; set; } 

     [Display(Name = "RegisterLabelStartService", ResourceType = typeof(Forms))] 
     public int StartServiceId { get; set; } 

     public ReadOnlyCollection<ServicePlugin> Services { get; private set; } 

     public Registration() 
     { 
      this.Services = new ReadOnlyCollection<ServicePlugin>(new List<ServicePlugin> { new ServicePlugin { Id = 1, DisplayName = "Mobile Services" }, new ServicePlugin { Id = 2, DisplayName = "Cable Services" } }); 
     } 
    } 
}

ServicePlugin.cs

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 

namespace TestApplication.Models 
{ 
    public class ServicePlugin 
    { 
     public int Id { get; set; } 

     public string DisplayName { get; set; } 
    } 
}

AccountController.cs

[AllowAnonymous] 
public ActionResult Register() 
{ 
    return this.View(); 
}

我注释掉Razor视图（一个有误差），因为我不能够正确地调试依赖于这个类的一部分。

具体来说，我想调试此行Registration.cs文件：

**public Registration()**

要弄清楚它是如何被填充和所使用的视图。

欣赏这样做的任何见解。

P.S.当我删除发生错误的Register.cshtml的注释时，出现错误：对象引用未设置为对象的实例。

我能在这一行设置一个断点：

@foreach(var m in Model.Services)

但型号是空和引发错误：

型“System.NullReferenceException”的异常出现在appXXXX.dll但没有在用户代码中处理。

所以我觉得我需要了解所有这些如何结合在一起。

在您的帐户控制器，你需要实例，然后将模型传递给视图，使用View方法的重载：

[AllowAnonymous] 
public ActionResult Register() 
{ 
    return View(new Models.Registration()); 
}
