Required to write an object-oriented program that reads a comma-delimited file of stock items and stores them in a typed collection. The format of the stock file, **[login to view URL]**, is a comma-delimited file, containing five fields: item code, item description, stock count, cost price and sales price. You will need to write three files: **[login to view URL]**, **[login to view URL]**, and **[login to view URL]**. The *InventoryManager* class will contain a Main() method that opens the file for reading, creates objects of type *StockItem* to store an individual record read from the stock file, and stores the StockItem objects into the *StockList* typed collection. If an attempt is made to create a StockItem with negative stock or with a cost price greater than a sales price, an exception should be thrown and handled (just use the builtin [login to view URL] type for this purpose).
