Q.
Session management in mvc?
A. You can manage session
using tempdata, viewdata, and viewbag in mvc.
TempData:-
Helps
to maintain data when you move from one controller to another controller or
from one action to another action.
Store
Syntax(Action):- TempData["Message"]
= "TempData Hello World";
Read
Syntax(View):- @{<p>@TempData["Message"]</p>}
Note:-
"TempData"
is once read it will not be available in the subsequent request. Call
"Keep" method, if we want to "TempData" available in the
subsequent request.
Read
Syntax(View):- @{
<p>@TempData["Message"]</p>
TempData.Keep("Message");
}
ViewData:-
Helps
to maintain data when you move from controller to view.
Store
Syntax(Action):- ViewData["Message"]
= "ViewData Hello World";
Read
Syntax(View):- @{<p>@ViewData["Message"]</p>}
ViewBag:-
It’s
a dynamic wrapper around view data. When you use Viewbag type, casting is not
required. It uses the dynamic keyword internally.
Store
Syntax(Action):- ViewBag.Message
= "ViewBag Hello World";
Read
Syntax(View):- @{<p>@ViewBag.Message</p>}
