C# 自定义asp存储中的HttpContext问题

我正在创建一个自定义ASP应用商店，下面是所显示的问题： 邀请经理类：

public InvitationManager(InvitationStore store)
    {
        Store = store ?? throw new ArgumentNullException(nameof(store));
        UserManager = Context.GetOwinContext().Get<ApplicationUserManager>();
    }

public async void SendInvitation(Invitation inv, ApplicationUser SentTo)
    {
        var SentToUser = await UserManager.FindByIdAsync(SentTo.Id);
        inv.SentTo = SentToUser;
        var SentBy = await UserManager.FindByNameAsync(Context.User.Identity.Name);
        inv.SentBy = SentBy.Id;
        var not = new Notification(Referenced_user: SentTo);
        inv.AssociatedNotification = not;
        SentToUser.Notifications.Add(not);
        await Store.CreateAsync(inv);
    }

public IQueryable<Invitation> Invitations
    {
        get
        {
            var queryableStore = Store.Invitations;
            if (queryableStore == null)
            {
                throw new NotSupportedException("Can't access database invitations");
            }
            return queryableStore;
        }
    }

protected HttpContext Context
    {
        get
        {
            return HttpContext.Current;
        }
    }

private ApplicationUserManager _userManager;
public ApplicationUserManager UserManager
    {
        get
        {
            if(_userManager == null)
            {
                _userManager = new ApplicationUserManager(new UserStore<ApplicationUser>(new ApplicationDbContext()));
            }
            return _userManager;
        }
        set
        {
            _userManager = value;
        }
    }

那我该怎么解决呢？如何使它们从相同的上下文中检索？

这里仍然是如何存储dbcontext及其与UserManager的关系：

app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);

public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) 
    {
        reurn new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
    }

app.CreatePerOwinContext（ApplicationDbContext.Create）；
app.CreatePerOwinContext（ApplicationUserManager.Create）；
公共静态应用程序SerManager创建（IdentityFactoryOptions选项，IOwinContext上下文）
{
重新注册新的ApplicationUserManager（新的用户存储（context.Get（））；
}

我对我的邀请存储执行了完全相同的过程，我从应用程序Startup.Auth.cs文件中声明的OwinContext中获取DbContext。每次用户发出HTTP请求时都会检索到它。

提供

UserManager

类的代码，这样我们就可以了解您是如何使用

DbContexr

的。UserManager代码是在ASP.Net中预实现的身份代码。这不是我的，这是微软预先实现的。请参阅和评论。

app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);

public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) 
    {
        reurn new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
    }
