Solution 2

Do a null check for the session prior to use it.
Try this-

C#

if (Session["userStatus"]!=null)
{
  if (Session["userStatus"].ToString() == "2")
  {
     return Redirect("/EditUserProfile");
  }
}

Hope, it helps :)

Couldn't understand what are you saying?

Arasappan 24-Nov-15 1:56am

U say

if (Session["userStatus"]!=null)
{

Where and when you get the value of Session["userStatus"],Then how it should be enter on the loop

Suvendu Shekhar Giri 24-Nov-15 2:04am

It must be set somewhere else in the application and definitely not in code shared by OP. It doesn't make any sense to set the session value here and cheking in the immediate next line for whether it is null or not.

Solution 3

C#

public ActionResult Index()
       {

           string a = "2";

       Session["userstatus"] = a;
           if (a!=null)
           {
           if (Session["userStatus"].ToString() == "2")
           {

               return Redirect("/EditUserProfile");
           }
           }

           return View("ActsRules");
       }

C#

Let me explain what you are suggesting, line by line-
string a = "2"; --declare a variable and set a value to it
Session["userstatus"] = a; --assign that value to a session variable
if (a!=null) -- chck whether the varibale is null or not

Why? you have set a value to that variable just before 1 line of code, don't you?
Then how you think the value will be changed to NULL?
