I already answered your question mangesh

here

and that is
Just create a class as follows

Class SessionClass
{
public string Value1;
public string Value2;
}

then,
.
.
.

SessionClass s=new SessionClass();
s.Value1="SomeValue1";
s.Value2="SomeValue2";

Session["MyKey"]=s;
.
.

SessionClass s1=(SessionClass)Session["MyKey"];

Or even you can use any other container like KeyValuePair ,Dictionary or list and then store them in session.

Hope this helped check this is correct answer if it is.
