Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v21.2.dll

Declaration

IList CreateCollection(
    Type objectType,
    CriteriaOperator criteria
)

Parameters

Name Type Description

The CriteriaOperator that specifies a criteria for object selection in a data store.

IList

A IList collection that includes the persistent objects of the specified type. In addition, only objects that satisfy the specified criteria will be retrieved to this collection.

Remarks

Use this method to create a collection of objects of the specified type, filtered according to the specified criteria. The newly created collection will use the current Object Space to load and save persistent objects.

If you implement the IObjectSpace interface in the BaseObjectSpace class’ descendant, you should override a virtual protected BaseObjectSpace.CreateCollection method which is called by the BaseObjectSpace.CreateCollection method.
