c# - How to get user information after successful authentication? -

the goal

get user information after successful authentication.

the problem

take in following fragment of code:

[acceptverbs(httpverbs.post)] [validateantiforgerytoken] [allowanonymous] public actionresult authenticate(user usermodel) {     if (modelstate.isvalid)     {         if (usermodel.isvalid(usermodel.email, usermodel.password))         {             formsauthentication                 .setauthcookie(usermodel.email, usermodel.remember);             return redirecttoaction("index", "manager");         }         else         {             modelstate.addmodelerror("", "login data incorrect!");         }     }     return redirecttoaction("index"); } 

as can see, normal authentication's controller. need simple: if statement usermodel.isvalid true, how can user information based on email sent server usermodel.email?

maybe store email on session , in index method call method (user) information passing through parameter email inhabiting session? (i think isn't best way because if cookie exist , session not, there problem here.)

code spotlight

to information of user, i'm using simple method: user.invoke((string) useremail).

knowledge improvement

i'm logging in on website email , password various applications of world do. email user enters, i'm attempting information database. ask: best way this? maybe isn't better firstly id of user email , select information?

what tried

in authenticate method (the same passed before), implemented following code:

[...] public actionresult authenticate(user usermodel)     [...]     if (usermodel.isvalid(usermodel, usermodel.password))     {         formsauthentication             .setauthcookie(usermodel.email, usermodel.remember);          session["useremail"] = usermodel.email; // <-- pay attention          return redirecttoaction("index", "manager");     }     [...] } 

and then, in index method:

public actionresult index() {     if(request.isauthenticated())     {         userprofile user = user.invoke(session["useremail"]));         return view(user);     }     else     {         return view();     } } 

but said, if cookie flags user logged in alive , session not, there problem right here — kind of concept conflict (cookie vs. session).

what can do?

the accepted answer (from discussion op) : straightforward way of retrieving user name set forms authentication module use

httpcontext.current.user.identity.name 

or just

this.user.identity.name 

in controller.
