Page.IsPostBack or IsPostBack

Question

I just wanted to know that is there any performance difference between these two statements

Page.IsPostBack

or

IsPostBack

Answer 1

There will be a difference at the IL level (an additional getter call in the first case) but it will be so negligible that you shouldn't bother at all.

Answer 2

There is no practical difference. The Page property merely exposes a reference to the same instance as this.
