我是 ASP.net 的新手，我正在嘗試使用 MVC。我有一個(gè)使用 Linq 從 sql 數(shù)據(jù)庫(kù)獲取當(dāng)前用戶信息的方法。我如何將這些結(jié)果放入視圖中并在網(wǎng)站的任何地方使用它們？我獲取用戶信息的方法：public List<AspNetUser> GetCurrentUser(){ FulfillmentContext db = new FulfillmentContext(); string username = HttpContext.Current.User.Identity.GetUserName(); var currentUser = (from u in db.AspNetUsers join ur in db.AspNetUserRoles on u.Id equals ur.UserId join r in db.AspNetRoles on ur.RoleId equals r.Id where u.UserName == username select u).ToList(); return currentUser;}

理想情況下，您應(yīng)該將其加載到您的模型中：
public ActionResult Index()
{
FulfillmentContext db = new FulfillmentContext();
string username =
HttpContext.Current.User.Identity.GetUserName();
var currentUser = (from u in db.AspNetUsers
join ur in db.AspNetUserRoles on u.Id equals ur.UserId
join r in db.AspNetRoles on ur.RoleId equals r.Id
where u.UserName == username
select u).First();
var model = new Model();
model.CurrentUser = currentUser;
return View(model);
}
但是，您可以創(chuàng)建一個(gè) HTML 幫助程序擴(kuò)展：
public static AspNetUser GetCurrentUser(this HtmlHelper helper)
{
FulfillmentContext db = new FulfillmentContext();
string username = HttpContext.Current.User.Identity.GetUserName();
var currentUser = (from u in db.AspNetUsers
join ur in db.AspNetUserRoles on u.Id equals ur.UserId
join r in db.AspNetRoles on ur.RoleId equals r.Id
where u.UserName == username
select u).First();
return currentUser;
}
然后從您的視圖中調(diào)用它：
@{
var user = Html.GetCurrentUser();
}
