KeyedByTypeCollection<TItem> Class

Definition

Namespace:

System.Collections.Generic

Assembly:

System.ServiceModel.Primitives.dll

Package:

System.ServiceModel.Primitives v8.1.0

Source:

KeyedByTypeCollection.cs

Provides a collection whose items are types that serve as keys.

generic <typename TItem>
public ref class KeyedByTypeCollection : System::Collections::ObjectModel::KeyedCollection<Type ^, TItem>

public class KeyedByTypeCollection<TItem> : System.Collections.ObjectModel.KeyedCollection<Type,TItem>

type KeyedByTypeCollection<'Item> = class
    inherit KeyedCollection<Type, 'Item>

Public Class KeyedByTypeCollection(Of TItem)
Inherits KeyedCollection(Of Type, TItem)

Type Parameters

TItem

The item types contained in the collection that also serve as the keys for the collection.

Inheritance

Object

Collection<TItem>

KeyedCollection<Type,TItem>

KeyedByTypeCollection<TItem>

Derived

System.ServiceModel.Channels.BindingParameterCollection

Remarks

Only one object of each type is allowed in the collection because the type is the key and each key must be unique. But you can find objects of different types.

Constructors

KeyedByTypeCollection<TItem>()	Initializes a new instance of the KeyedByTypeCollection<TItem> class.
KeyedByTypeCollection<TItem>(IEnumerable<TItem>)	Initializes a new instance of the KeyedByTypeCollection<TItem> class for a specified enumeration of objects.
