Type Parameters

T

The type of items stored in the set.

Constructors

ReadOnlyObservableSet<T>(IEqualityComparer<T>)

Initializes a new instance of the ReadOnlyObservableSet<T> class that is empty and uses the specified equality comparer for the set type..

Properties

Count

Gets the number of elements actually contained in the ReadOnlyObservableSet<T>.

Methods

AddItem(T)	Adds the specified element to a set.
ClearItems()	Removes all elements from a ReadOnlyObservableSet<T> object.
Contains(Object)	Determines whether an element is in the ReadOnlyObservableSet<T>.
Contains(T)	Determines whether an element is in the ReadOnlyObservableSet<T>.
GetEnumerator()	Returns an enumerator that iterates through the ReadOnlyObservableSet<T>.
OnCollectionChanged(NotifyCollectionChangedEventArgs)	Invoked when the collection is changed.
OnItemAdded(T)	Invoked when an element is added to the set.
OnItemRemoved(T)	Invoked when an element is removed from the set.
OnItemsCleared(IEnumerable<T>)	Invoked when the set is cleared.
RemoveItem(T)	Removes the specified element from a ReadOnlyObservableSet<T> object.

Events

CollectionChanged

Occurs when an item is added, removed, changed, moved, or the entire set is refreshed.

Explicit Interface Implementations

IEnumerable.GetEnumerator()

Returns an enumerator that iterates through the ReadOnlyObservableSet<T>.

Extension Methods
