Hash tables are not specific to C#. A hash table is a dynamic set data structure. It has three basic functions: to store data (SET/INSERT); to retrieve data (SEARCH/RETRIEVE), and to remove data that has previously been stored in the set (DELETE). In this way it is not different from other dynamic set data structure such as linked lists or trees. What is interesting about hash tables is their performance characteristics with respect to the store/retrieve/remove operations.
Understanding Dropshipping. Dropshipping is a retail fulfillment method where a store doesn't keep the products it sells in stock. Instead, when a store sells a product, it purchases the item from a third party and has it shipped directly to the customer. As a result, the merchant never sees or handles the product.
From the Shipping Queue, you can delete (cancel) a shipment. 1  Click the Shipment Name or the Work on Shipment button (this will be View and Track if the status is Shipped or later). 2  Click Delete Shipment or Cancel Shipment (depending on shipment status) at the bottom of the screen.
