Question

我创建了这个视图模型类：

using System.Collections.Generic;
using Microsoft.Azure.ActiveDirectory.GraphClient;

namespace xx.Models.GlobalAdmin.Models
{
    public class UserViewModel
    {
        public  User Usuario { get; set; }
        public List<string> SelectedCompanies { get; set; }
    }
}

我将Create.cshtml从User类从Active目录更改为：

@model CapatechSaasApp.Models.GlobalAdmin.Models.UserViewModel

以及所有这些控件：

<div class="form-group">
    @Html.Label("Usuario", new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        <div class="input-group">
            @Html.EditorFor(model => model.Usuario.UserPrincipalName)
            <span class="input-group-addon" id="basic-addon2">@SettingsHelper.Domain.ToString()</span>
            @Html.Validatiomodel => model.Usuario.UserPrincipalName)
        </div>
    </div>
</div>

我还将Create操作更改为：

public async Task<ActionResult> Create(
    [Bind(Include = "UserPrincipalName,AccountEnabled,PasswordProfile,MailNickname,DisplayName,GivenName,Surname,JobTitle,Department"
                )] CapatechSaasApp.Models.GlobalAdmin.Models.UserViewModel user, FormCollection formCollection)
        {
            ActiveDirectoryClient client;
            try
            {
                client = AuthenticationHelper.GetActiveDirectoryClient();
            }
            catch (Exception)
            {
                if (Request.QueryString["reauth"] == "True")
                {
                    //
                    // Send an OpenID Connect sign-in request to get a new set of tokens.
                    // If the user still has a valid session with Azure AD, they will not be prompted for their credentials.
                    // The OpenID Connect middleware will return to this controller after the sign-in response has been handled.
                    //
                    HttpContext.GetOwinContext()
                        .Authentication.Challenge(OpenIdConnectAuthenticationDefaults.AuthenticationType);
                }

                //
                // The user needs to re-authorize.  Show them a message to that effect.
                //
                ViewBag.ErrorMessage = "AuthorizationRequired";
                return View();
            }

            try
            {
                var usuario = user.Usuario.UserPrincipalName;
                user.Usuario.UserPrincipalName = usuario+SettingsHelper.Domain;
                user.Usuario.MailNickname = usuario;
                user.Usuario.AccountEnabled = true;
                await client.Users.AddUserAsync(user.Usuario);

                //Setting extended property lookup name
                var extPropLookupName = $"extension_{SettingsHelper.ClientId.Replace("-", "")}_{"Compania"}";

                //TO BE FINISHED
                user.Usuario.SetExtendedProperty(extPropLookupName, formCollection["Empresa"]);
                await user.Usuario.UpdateAsync();
                //Task.WaitAll();

                // Save the extended property value to Azure AD.
                user.Usuario.GetContext().SaveChanges();
                return RedirectToAction("Index");
            }
            catch (Exception exception)
            {
                ModelState.AddModelError("", exception.Message);
                return View();
            }
        }

但是user.Usuario始终为Null，我无法获取在表单上键入的值。

我想

可能有问题

[Bind(
                    Include =

但我不知道它是什么或语法

Answer 1

首先，我不知道什么是最糟糕的，沿着代码传播的神奇字符串，丑陋的架构或基本上将所有mvc版本标签添加到问题而不是您正在处理的版本的事实

该绑定是一个模型绑定器。

通过Model Binder的定义当＆＃34;创建＆＃34;执行MVC模型绑定器将使用请求参数来填充用户参数的属性，您应该知道。但是，Bind属性告诉模型绑定器仅填充指定名称的属性。

我击败了＆＃34; Usuario＆＃34;永远是null，因为你没有在这个丑陋的巨型魔法字符串中传递属性

[Bind(Include = "UserPrincipalName,AccountEnabled,PasswordProfile,MailNickname,DisplayName,GivenName,Surname,JobTitle,Department"

创建
