包含路径表达式必须引用的类型所限定的导航属性

Question

我有以下库方法： -

public AccountDefinition GetCustomer2(int id) 
{ 
    var c = entities.AccountDefinitions 
      .Where(p=>p.ORG_ID==id) 
      .Include(a => a.SDOrganization) 
      .Include(a2 => a2.SiteDefinitions) 
      .Include(a3 => a3.SDOrganization.AaaPostalAddresses) 
      .Include(a4 => a4.SiteDefinitions.SelectMany 
           (a5 => a5.DepartmentDefinitions.SelectMany 
            (a6 => a6.SDUsers.Select 
              (a7 => a7.AaaUser)))) 
                .SingleOrDefault(); 

    return c; 
} 

的它调用上述方法中的以下动作的方法： -

public ActionResult Details2(int id = 0) 
{ 
    AccountDefinition cd = repository.GetCustomer2(id); 
    return View("copy",cd); 
} 

但当我导航到操作方法时，我在存储库类上出现以下错误： -

The Include path expression must refer to a navigation property defined on the type. Use dotted paths for reference navigation properties and the Select operator for collection navigation properties.

那么我的代码有什么问题？

我想你可能要像做

public AccountDefinition GetCustomer2(int id) 
     { 

      var c = entities.AccountDefinitions.Where(p=>p.ORG_ID==id) 
       .Include(a => a.SDOrganization) 
       .Include(a2 => a2.SiteDefinitions) 
       .Include(a3 => a3.SDOrganization.AaaPostalAddresses) 
       .Include(a4 => a4.SiteDefinitions.Select(a5 => a5.DepartmentDefinitions.Select(a6 => a6.SDUsers.Select(a7 => a7.AaaUser)))); 

      return c; 
     }
