List.ToLookup Example in C#

Sometimes when we have a list of objects and we need to look up that collection by a member item in the object, we could easily benefit from converting a List collection into a Lookup collection. For example, we need to look up an entire product's inventory in a store by their Supply Date or by their price etc.
             So, to get a Lookup from a list we use the extension method "ToLookup" available in a List collection's extension methods.
