Get the ID of the current user ASP.NET Membership

问题

How do you guys manage to get the ID of the current user using the ASP.NET Membership Provider? My application is an MVC 3 using Database First approach, so I created my own database and the Membership Provider and Role Provider are using my tables (Custom Membership and Role Provider).

In one of my page (feedback), user can send feedback about my website and if he's connected, I want to include the UserID in the table when I insert.

But since the ASP.NET Membership is an IIdentity, the only thing I can access is the Name. I don't want to create a link between 2 tables using the name, I want the ID!

So what do you do in your application for this VERY simple task? I mean, in almost every page where a connected user needs to insert a value, we need the ID of the user to create the correct foreign key to the user table, right? By the way, I'm very new to this MVC framework, before that I was using ASP.NET aspx and for the user information, I was using the Session which gave me the current ID, Name and other fields as needed. Since this implementation using the Session object gave me trouble in shared hosting, I want to use the real membership.

Thanks!

EDIT

The ID I want must be an integer (in fact, I want the UserID field that is in the User table).

回答1:

Try this;

MembershipUser mu = Membership.GetUser("username");
string userId = mu.ProviderUserKey.ToString();

For currently logged in user you could use without passing the username;

string userId = Membership.GetUser().ProviderUserKey.ToString();

I wanted to share how to get the UserId for Identity 2.0:

string UserId = System.Web.HttpContext.Current.User.Identity.GetUserId();

I ran into a similar problem. I (for other reasons, as well) made a base Controller class that all of my other controllers inherited from. You can have the base class hold the user's information for use at any time.

assuming you have everything configured correctly for your providor in your web.config, and since you can get the username, I recommend:

Dim muser As MembershipUser = Membership.GetUser(userName)

Here are details on the MembershipUser object: http://msdn.microsoft.com/query/dev10.query?appId=Dev10IDEF1&l=EN-US&k=k%28SYSTEM.WEB.SECURITY.MEMBERSHIPUSER%29;k%28TargetFrameworkMoniker-%22.NETFRAMEWORK%2cVERSION%3dV4.0%22%29;k%28DevLang-VB%29&rd=true

many properties other than name available. The ID feild you want is called 'ProviderUserKey'

回答5:

Could this be what your after?

userid from asp.net Membership Authentication?

Personally I have my own class which encapsulates retrieving these details by the username plus any custom data I require in my application.

To get current UserID you can try following

string currentUserId= Convert.ToString(Membership.GetUser().ProviderUserKey);
