(Update: 12/20/2021 - This is a very old blog. Some of the properties have changed. Contact us at support@noptools.com for up-to-date information.)
The previous blog discussed expressions, and that the underlying attributes of the Shopping Cart can be referenced. Below is a partial shopping cart hierarchy. You use a dot (".") between attributes in the hierachy to reference children. Some attributes are collections (lists), that can contain 0 or more other objects. All expressions must yield a scalar value, so collections must have some Query Operator applied like All() [a boolean], or Sum() [a decimal].
Some query operators, like All(), will return a boolean. For example, Any() will return true if any items in the collection meet the criteria. For example - The customer has the Administrator role:
Customer.CustomerRoles.Any(Name = "Administrators")
Some query operators, like Where(), will return a subset which is still a collection, so a First() operator must then be applied and then probably followed with an attribute name. This Where().First() is a common scenario. For example, check if customer has the role with Any() above, and then check if that role is Active:
and Customer.CustomerRoles.Where(Name = "Administrators").First().Active
