Question

我有一个扩展IdentityRole类的类：

public class Subscription : IdentityRole
    {
        //parameterless construcor required by EF
        public Subscription() { }

        public Subscription(string roleName) : base(roleName)
        {
        }

        public string SubscriptionID { get; set; }
        public override string Name { get; set; }
        public DateTime? Expiration { get; set; }
    }

在AppUser扩展IdenityUser

的

public class AppUser : IdentityUser
    {
        public Subscription UserSubscription { get; set; } = new Subscription();
    }

类中使用

Subscription

在我的控制器中，我使用UserSubscription类中的方法设置model.Subsubscription属性，其中//it's been verified that the user properties are correctly set here user.UserSubscription.SetSubscription(user.UserSubscription, model.Subscription); return RedirectToAction("IndexUser");是一个字符串

user.UserSubscription.Name

但是，当我呈现以下视图时，@{ ViewBag.Title = "User Accounts"; Layout = "_AdminLayout"; } @model IEnumerable<AppUser> <div class="bg-primary panel-body"><h4>@ViewBag.Title</h4></div> <table class="table table-condensed table-bordered"> <tr><th>ID</th><th>Name</th><th>Subscription Type</th><th>Email</th></tr> @if (Model.Count() == 0) { <tr><td colspan="3" class="text-center">No User Accounts</td></tr> } else { foreach (AppUser user in Model) { <tr> <td>@user.Id</td><td>@user.UserName</td><td>@user.UserSubscription.Name</td><td>@user.Email</td> <td> <form asp-action="DeleteUser" asp-route-id="@user.Id" method="post"> <a class="btn btn-sm btn-primary" asp-action="EditUser" asp-route-id="@user.Id">Edit</a> <button type="submit" class="btn btn-sm btn-danger">Delete</button> </form> </td> </tr> } } </table> <a class="btn btn-primary" asp-action="CreateUser">Create</a>属性为空

user.UserSubscription.Name

在视图中，除AppUser外，所有其他属性都正确显示。为什么这些数据没有传输到视图？我觉得这可能是由于UserSubscription班级public void SetSubscription(Subscription subscription, string subType) { var subscriptionType = subType.ToLower(); if (subscriptionType == "t0") { subscription.Name = "T0"; subscription.Expiration = null; } else if (subscriptionType == "t1") { subscription.Name = "T1"; subscription.Expiration = DateTime.Now.AddYears(1); } else if (subscriptionType == "t2") { subscription.Name = "T2"; subscription.Expiration = DateTime.Now.AddYears(1); } else if (subscriptionType == "t3") { subscription.Name = "T3"; subscription.Expiration = DateTime.Now.AddYears(1); } }属性造成的，但我不确定如何正确设置

编辑：共享SetSubscription方法

userManager.Users

虽然在重定向之前的CreateUser操作方法中似乎是正确的，但是当通过public IActionResult IndexUser() => View(userManager.Users);传递时，UserSubscription Name属性为空

IdentityRole

我能够通过删除扩展AppUser并扩展public class AppUser : IdentityUser { public string Substription { get; set; } public DateTime? Expiration { get; set; } }类

的Subscription.cs类来解决此问题。

@user.Subscription

然后我使用类似的SetSubscription（）方法设置AppUser属性并将视图更改为显示SELECT CELLS.ID, CELLS.NAME, CELLS.NUM, CELLS.AC_ID, AC.SERIAL,AC.FILE_NAME, AC.FILE_DATA FROM CELLS LEFT JOIN AC ON CELLS.AC_ID = AC.ID WHERE CELLS.AC_ID IS NOT NULL ORDER BY CELLS.NUM并且它有效。这有简化我的控制器代码的附带好处。我剩下的问题是：扩展IdentityUser类而不是IdentityRole类是否会阻止我以后可能需要的某些功能？
