How to use Context Object in ASP.Net C#

The ASP.Net Context object is the same as the Session Object as we learnt previous asp.net post.

The Context Object is used to store the Value and Send it to the other page in ASP.Net.

The main Difference between Context and Session is the Context Object will be null when we send page to server.
That means we we use Context Object we must use Server.Transfer Method to redirect user to other page.

If we use Response.Redirect the Context value will be null on other page.

we can use Response.Redirect and Server.Transfer with Session Object in ASP.Net, but Response.Redirect cant use with Context Object in ASP.Net.
