So
I know about Array, Try catch, IF, Fields etc.
I know Methods, classes, enum etc.

Do i really have to go thru Interfaces, Delegates, Events etc.

B4 i start ASP.NET ? Or all more advanced thinks i can learn while there will be need.

You atleast need to go through events to understand how the button click event takes place etc...

before you start basis of ASP.NET in scenarios where you want to create User Controls etc.. in ASP.NET you will have to learn about Interfaces , Delegates and other important factors like inheritance, overloading , overriding etc..
