GetUser.ProviderUserKey gives me System.NullReferenceException

[Cirene]

Using asp.net membership. My login.aspx page goes to the loginredirect.a spx
page after the user logs in.

For some reason "Membership.Get User.ProviderUs erKey.ToString" gives me this
error:
System.NullRefe renceException: Object reference not set to an instance of an
object. at loginredirect.P age_Load(Object sender, EventArgs e)

Any reason why? I should be logged in fine.

Is there another way in which I should get the current users UserId?

Re: GetUser.Provide rUserKey gives me System.NullRefe renceException

Membership.GetU ser() is definitely null in your case. Meaning that the user
has not actually been logged in. Can't say much since unsure about your
particular scenario.

The authentication principal won't get set until the next request to the
web-server. That's why GetUser returns. But you can use the "UserName"
property of the Login control
within the LoggedIn event to identify the user. With this name, you can use
Membership.GetU ser(userName).

I recommend you surround the code with some checks first, like this:

If User.Identity.I sAuthenticated Then Begin
myString := Membership.GetU ser().ProviderU serKey.ToString
End Else Begin
Response.Write( 'User is not logged in.');
Response.End;
End;

{yes, that's Delphi ;-) }

Step through that code in the debugger to find out if it goes down the
"IsAuthenticate d " path. If not then you know what the problem is.

I'd prefer the following to make a safer access to ProviderUserKey property:

var user = Membership.GetU ser();

if(user == null)
{
// not authenticated, please log in
}
else
{
// play with the currently logged in user.
}
