public class DistinctInstanceCollection<T> : IEnumerable<T>, 
	IEnumerable

Public Class DistinctInstanceCollection(Of T) _
	Implements IEnumerable(Of T), IEnumerable

Type Parameters

Distinct instances are used by some contract verifiers such as CollectionContract<(Of <(TCollection, TItem>)>) to check for the correct implementation of the collection interface.

Use the default constructor followed by a list initializer.

CopyC#

var collection = new DistinctInstanceCollection<Foo>
{
    new Foo(1)
    new Foo(2),
    new Foo(3),
};

Or, use the single-parameter constructor to create a collection from an pre-existing enumeration.

CopyC#

var collection = new DistinctInstanceCollection<Foo>(Foo.GetThemAll());
