Type Parameters

Name	Description
T

The type of elements in the collection.

Remarks

The XPCollection<T> class is a collection of persistent objects, much like the XPCollection. The only difference is that the XPCollection<T> is a generic type collection, which contains persistent objects as specified by T , and as a result, the collection cannot be used as a data source at design time.

Example:

C#
VB.NET

csharp

XPCollection<Person> persons = new XPCollection<Person>(session1, 
    CriteriaOperator.Parse("FirstName = 'John'"));

Dim persons As New XPCollection(Of Person)(session1, _
CriteriaOperator.Parse("FirstName = 'John'"))

As with the XPCollection, the XPCollection<T> is used to query data stores for specific objects and to represent the “many” end of object associations.
