We have a web project (using asp.net)to make a website for a business and we struggled doing these points:

1-How to upload an image into the database(using asp.net #C)?

2-How to add a product to cart (using asp.net #C)?

3-How to insert and update data in database from a form (using asp.net #C)?

If any one can help us answering these questions with clear explanation and coding I'll be very grateful.
