C# 显示来自aspnet.db的数据

在花了相当长的时间尝试配置web.config之后，我终于完成了配置，只是为了得到以下错误：

An exception of type 'System.InvalidOperationException' occurred in System.Web.dll but was not handled in user code

Additional information: Data source is an invalid type.  It must be either an IListSource, IEnumerable, or IDataSource.

我正在尝试连接到aspnet.db（我想我这样做是因为我没有连接错误，我从应用程序提供的普通web.config复制粘贴了它） 这是web.config：

<?xml version="1.0" encoding="utf-8"?>

这是我试图显示来自AspNetUsers的用户的页面（应用程序非常友好地为您创建了该页面，以便登录功能正常工作）：

最后但并非最不重要的一点是，页面背后的代码应该向GridView提供数据：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Security;
using Owin;
using SiteStiri.Models;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.Owin;

namespace SiteStiri.Administration
{
    public partial class ManageUsers : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                BindUserAccounts();

            }
        }
        private void BindUserAccounts()
        {
            UserAccounts.DataSource = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
            UserAccounts.DataBind();
        }

        private void BindFilteringUI() { 
            string[] filterOptions = { "All", "A", "B", "C", "D", "E", "F", "G", "H",
                                         "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z" };
            FilteringUI.DataSource = filterOptions; 
            FilteringUI.DataBind();
        }
    }
}

使用系统；
使用System.Collections.Generic；
使用System.Linq；

使用System.Web.UI；
使用System.Web.UI.WebControl；
使用System.Web.Security；
使用Owin；

}

我做错了什么？我是说msd的人，在他们的教程中可以这样显示数据：（

提前感谢您试图帮助我。

这句话：

UserAccounts.DataSource = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();

你的答案很完美。有一个问题。这个出色的UserManager没有检索所有用户的电子邮件/ID/或任何其他内容的方法，它只能检索1…这让我非常难过…完成了。非常感谢andrei。我设法为用户创建了一个列表：D.var manager=Context.GetOwinContext（）.GetUserManager（）；UserAccounts.DataSource=manager.Users.ToList（）；UserAccounts.DataBind（）；这是你第二次帮助我了。我非常爱你！@LucianTarna很高兴你帮了我。我通常会在asp.net标签附近闲逛，所以我们可能会再次见面

UserAccounts.DataSource = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();

var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
UserAccounts.DataSource = manager.GetUserList(); // Just a made up method, use what you need here
UserAccounts.DataBind();
