Business value
In the Business Central AL language, dictionaries and lists are powerful data structures that offer efficient lookup of key-value pairs and ordered collections, and both allowing managing collections of data dynamically. We're now adding the ability to have lists and dictionaries of interfaces, providing more flexibility and power when you work with interface abstractions.
Feature details
You can now create lists or dictionaries of interfaces.
The syntax follows these patterns, aligned with creating a List or Dictionary of a simple type:
- List of [Interface IFoo]
- Dictionary of [; Interface IFoo]
In the System Application, you can find the complete examples of using a list of interfaces in the Telemetry Logger.
The following examples illustrate creating lists and dictionaries with interfaces.
