====== ThinkGeo.MapSuite.MvcEdition.GeoKeyedCollection‹T› ======

{{section>upgrade_map_suite_to_10.0}}




<!-- Class -->
Represents a strong-typed collection that can be accessed by index or by the identifier of an item.
=== Remarks ===
The GeoKeyedCollection class is a hybrid between a collection based on the IList generic interface and a collection based on the IDictionary generic interface. Like collections based on the IList generic interface, KeyedCollection is an indexed list of items. Like collections based on the IDictionary generic interface, KeyedCollection has a key associated with each element.

The types that can be added to the GeoKeyedCollection must implement the IRequireId interface, which forces these types to have an Id property. Thus, we can get the item by identifier from the GeoKeyedCollection. The identifier must be unique and cannot be empty.
