Once the user has logged in then you can find out User.Identity.Name

You can then use this to return the UserId and therefore reference to aspnet_Membership, aspnet_sersInRoles etc.

If anyone knows a more elegant way then please post it here as I would also be interested

First include "System.Web.Security" namespace

Code:
using System.Web.Security;
then in your method (function) where you want to get user id write:

 Membership.GetUser().ProviderUserKey;

if you want to add it to the string you must convert it to string but first check if the user id logged in
Code:
string userID;

if (User.Identity.IsAuthenticated)
{
      userID = Membership.GetUser().ProviderUserKey.ToString();
}
Hope that this helps,
Haris

Hi,
    I am also trying to get userId. I am using the following command:
(Guid)Membership.GetUser().ProviderUserKey
I am assigning this value to a guid variable. But, I am getting a error like:

System.NullReferenceException was unhandled by user code
  Message="Object reference not set to an instance of an object."
  Source="App_Web_ghqgbxbt"

Hope someone will help me.

Thanks

checking to see if the user is authenticated is critical at this point, my guess is that you dont have a user auth. so you're trying to get a providerkey for a null user. GetUser() also accepts a string argument so you can specify which user you want (ie GetUser("Steve") if you are editing data for users on your site.


Hope that helps.
