                    Response.Cookies["aa"].Expires = DateTime.Now.AddDays(1);

                }
                else
                {
                    Response.Cookies["aa"].Value = Request.Cookies["aa"].Value.ToString() + "|" + product_id.ToString() + "," + product_name.ToString() + "," + product_desc.ToString() + "," + product_price.ToString() + "," + product_qty.ToString() + "," + product_images.ToString() + "," + data_id.ToString();
                    Response.Cookies["aa"].Expires = DateTime.Now.AddDays(1);

Debug your code and see which object is null.

This is not a problem in source code, this a problem at runtime, and we can't do anything for you.
Your only solution is using the debugger and inspect variables/objects at point of failure.

There is a tool that allow you to see what your code is doing, its name is debugger. It is also a great learning tool because it show you reality and you can see which expectation match reality.
When you don't understand what your code is doing or why it does what it does, the answer is debugger.
Use the debugger to see what your code is doing. Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

Debugger - Wikipedia, the free encyclopedia[^]
Debugging C# Code in Visual Studio - YouTube[^]
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to.
