Which line is giving the error? Have you tried debugging?

1.This error occurs because you are trying to access the property/method of a null object.

2.You should Debug your code and inspect in your code that generate the exception the values of the used variables, and one of it should be null.

PS: Normally when you read something from Session you should test it if is null or not. if(Session["FileDetail"] != null && Session["FileDetail"].ToString() != "")){...}

i have debugged my code no error comes but still it is giving object refernece error??
Additional to the Solution 1, kindly check for the variables. Maybe they don't generate a value that's why you're getting an exception.

If you are using Visual Studio, use breakpoint so that you can see in what specific line you are having problems with.
