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.

Solution 1

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.

Solution 2

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?

Solution 3

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 :)

Simple Membership? ASP.NET Membership?

Hmm, I'm getting: Error 1 'System.Web.Security.MembershipUser' does not contain a definition for 'GetUser'

Thanks, typo there, it was suppose to be Membership.

As long as your provider follows the requirements to use an int as the Unique Identifier.

Membership.GetUser().UserName for the username instead of the internal membership database key

This solution is not possible if the user is already logged in and trying to change the current password.
