Get logged in user's id

Question

How can I get the logged in user's UserId? I'm using the standard system generated AccountModel. I can get the username using:

User.Identity.Name

but I don't see the UserId field. I want to use the UserId as a foreign key for another table.

Try this:

using Microsoft.AspNet.Identity;
User.Identity.GetUserId();

That's how its done in the partial views for current MVC (MVC5/EF6/VS2013) templates.

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?

This solution is not possible if the user is already logged in and trying to change the current password. – usefulBee Nov 07 '16 at 19:57

I think you're looking for ProviderUserKey - Gets the user identifier from the membership data source for the user.

object id = Membership.GetUser().ProviderUserKey

Membership.GetUser() - Gets the information from the data source and updates the last-activity date/time stamp for the current logged-on membership user.

Hmm, I'm getting: Error 1 'System.Web.Security.MembershipUser' does not contain a definition for 'GetUser' – naveed Dec 21 '12 at 18:18
Thanks, typo there, it was suppose to be `Membership`. – Erik Philips Dec 21 '12 at 18:19
Membership.GetUser().UserName for the username instead of the internal membership database key – Marcello Grechi Lins Oct 15 '14 at 16:23

The best way to do so is to use the WebSecurty class

var memberId = WebSecurity.GetUserId(User.Identity.Name);

and don't forget to add [InitializeSimpleMembership] on top of your controller :)

As long as your provider follows the requirements to use an `int` as the Unique Identifier. – Erik Philips Jun 30 '13 at 02:23

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.

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.

Get logged in user's id
