Storing more data in Session is not good idea. It will degrade your performance. I am not sure why do you want put 1 lac record in session please describe it. Instead if you have have cache server you can use it.

I have Lacks of records in DB. I need to search the record by account number. Each and every time i cant go to DB and fetch record. Since it will make some performance issue. So i m planning to use Session variable, which will store Lacks of record and using LINQ query , I m planning to get the account details.

In that scenario you use look up concept. Store data in a file(xml) file and retrieve record as per your account number using LINQ query.

Of course, there will be a performance hit.
Generally, it is a very bad idea. Why would you want to store that big size of data in session. If you want to know more about the session size limit, see this thread

I can see what you are trying to do. You have to do some testing before taking a decision. Is the production server capable of handling 1 Lac records without affecting overall performance? Can you cache them rather than keeping them in session if is application wide and not session specific?

Can we use application variable ?

John C Rayan 28-Oct-15 6:07am

You can use but I would prefer Cache. Search for the the difference between Application State and Cache. Cache is better because it is more flexible and application variable will hurt the web server

Ok. than we can go ahead with cache.
