如何获取登录用户的 UserId？我正在使用标准系统生成的 AccountModel。我可以使用以下方法获取用户名：
User.Identity.Name
but I don't see the UserId field. I want to use the UserId as a foreign key for another table.

I think you're looking for ProviderUserKey - Gets the user identifier from the membership data source for the user.
我认为您正在寻找ProviderUserKey - 从用户的成员资格数据源获取用户标识符。
object id = Membership.GetUser().ProviderUserKey

The best way to do so is to use the WebSecurty class
最好的方法是使用 WebSecurty 类
var memberId = WebSecurity.GetUserId(User.Identity.Name);
and don't forget to add [InitializeSimpleMembership]on top of your controller :)
并且不要忘记添加[InitializeSimpleMembership]到您的控制器之上:)

Try this:
尝试这个：
using Microsoft.AspNet.Identity;
User.Identity.GetUserId();
That's how its done in the partial views for current MVC (MVC5/EF6/VS2013) templates.
这就是它如何在当前 MVC (MVC5/EF6/VS2013) 模板的部分视图中完成的。
Correct me if I'm wrong, because I've seen Aviatrix's answers a lot, but what happens if more than one user has the same name in the database?
如果我错了，请纠正我，因为我经常看到 Aviatrix 的答案，但是如果数据库中有多个用户具有相同的名称会发生什么？

Their are already very good answer but what i understood from your question is that you want to fetch data from database using id.so here is what you can do.
他们已经是很好的答案，但我从你的问题中了解到你想使用 id.so 从数据库中获取数据，所以你可以这样做。
public List<ForeignkeyTable> RV()
{
var email = User.Identity.Name;
Usertable m = db.Uusertables.Where(x => x.user_Email == email).SingleOrDefault();
var id = m.user_Id;
var p = db.ForeignkeyTable.Where(x => x.user_fk_id == id).ToList();
return p;
}
This way you can return all the data from database of that id in foreignkey.
通过这种方式，您可以从外键中该 id 的数据库中返回所有数据。
