XPCollection(Type, CriteriaOperator, SortProperty[]) Constructor

Initializes a new instance of the XPCollection class with default Session and criteria-specific options.

Namespace: DevExpress.Xpo

Assembly: DevExpress.Xpo.v21.1.dll


public XPCollection(
    Type objType,
    CriteriaOperator theCriteria,
    params SortProperty[] sortProperties


Name Type Description
objType Type

The type of persistent objects to include into the collection.

theCriteria CriteriaOperator

The CriteriaOperator that specifies the criteria for object selection.

sortProperties SortProperty[]

An array of SortProperty that specifies the sort order for the collection.


If the XPBaseCollection.LoadingEnabled property is set to true (default value) the collection is populated with objects when its contents are accessed for the first time (for instance, when the XPBaseCollection.Count property is read).

The newly created collection will use the default session (Session.DefaultSession) to load and save persistent objects.
