When a new meta-enum is created, a meta-type with the McDataType property and McDataType.Enum value is registered. If an enumerator has been created, you can create a new field with the enumerator meta-type. The entity object property returns the selected item ID (Int32) or an array of selected item IDs (Int32\[]).

Note

When you create and delete meta-enums, remember that you can only modify a meta-model in **Design** mode. See the [MetaClassManager class](🔗) section.

## Get an enumerator collection

Because the enumerator is an original meta-type, you can get all enumerators from the MetaClassManager.RegisteredTypes property.

**Example:** Find all enumerators
