This code is for a button click event in an ASP.NET page. When the button is clicked, it first gets the "id" parameter from the query string and updates the "JinHuo" table to mark the item as received.

Then, it retrieves the current inventory information for the product using the "ShangPinId" stored in a hidden field. If there is already an inventory record for the product, it updates the quantity by adding the value entered in a text box. Otherwise, it inserts a new record with the product information and quantity entered.

Finally, it displays a message to the user and redirects them to the "AddStore.aspx" page
