Question

我正在尝试授权特定用户只查看自己的公司数据。我在ApplicationUser中创建了一个名为CompanyId的自定义字段，并创建了一个CompanyController（在Erik Funkenbusch的帮助下），如下所示：

public class CompanyController : Controller
{
    private ApplicationDbContext db = new ApplicationDbContext();

    // GET: Company
    public ActionResult Index()

{
        var companies = from c in db.Companies
                        join u in db.AspNetUsers
                        on c.CompanyID equals u.Company.Id
                        where u.UserName = User.Identity.Name
                        select c;
        return View(companies);
    }

但是：db.AspNetUsers在VS2017中的ApplicationDbContext＆＃39; -error中返回＆＃39;不包含定义。我在俯瞰什么？我的上下文（仍然）非常标准，看起来如下：

public class ApplicationDbContext : IdentityDbContext<ApplicationUser> { public ApplicationDbContext() : base("DefaultConnection", throwIfV1Schema: false) { } static ApplicationDbContext() { // Set the database intializer which is run once during application start // This seeds the database with admin user credentials and admin role Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer()); } public static ApplicationDbContext Create() { return new ApplicationDbContext(); } public DbSet<Company> Companies { get; set; }

我认为问题在于SaveFileDialog svg = new SaveFileDialog(); svg.ShowDialog(); PdfWriter.GetInstance(document, new FileStream(svg.FileName + ".pdf", FileMode.Create));上包含用户的属性称为IdentityDbContext<T>而不是Users。见here

所以你应该试试这个：

AspNetUsers

（使用var companies = from c in db.Companies join u in db.Users on c.CompanyID equals u.Company.Id where u.UserName == User.Identity.Name select c;代替db.Users）

发现该部分

让AspNetUsers加入自定义表
