asked on Session expired but doesnt redirect, throws an error
I have the code below to redirect when the session is expired. Instead of redirecting after the session is expired, it throws this error
Object reference not set to an instance of an object.
Why is that? why isn't it redirecting? how can I fix it?

doesnt IsNullOrEmpty check for null?
Session["BusinessId"].ToSt

But i have it in a IsNullOrEmpty..
Now, If I change it to below..in that case it goes to redirect line. No object null error. Why is it like that...is it because string businessId = Session["BusinessId"].ToSt
initializes it to an empty string?
private int BusinessNameId
{
get
{
string businessId = Session["BusinessId"].ToSt
if (string.IsNullOrEmpty(businessId))
{
Response.Redirect("~/Sessi
}
return int.Parse(Session["Busines
}
}

So I should change it what informaniac has?
Even this should work:
private int BusinessNameId
{
get
{
string businessId = Session["BusinessId"] as string;
if (string.IsNullOrEmpty(businessId))
{
Response.Redirect("~/SessionExpired.aspx");
}
return int.Parse(Session["BusinessId"].ToString());
}
}
