View a set of collections as one continuous list.

Similar to the System.Windows.Data.CompositeCollection, plus:

Generic type
Transparent separation of the real content and the resulting list

Syntax

Copy

public sealed class ObservableCompositeCollection<T> : ReadOnlyObservableCollection<T>, 
	IObservableCollection<T>, IList<T>, ICollection<T>, IEnumerable<T>, 
	IEnumerable, INotifyCollectionChanged, INotifyPropertyChanged

Public NotInheritable Class ObservableCompositeCollection(Of T)
	Inherits ReadOnlyObservableCollection(Of T)
	Implements IObservableCollection(Of T), IList(Of T), 
	ICollection(Of T), IEnumerable(Of T), IEnumerable, INotifyCollectionChanged, 
	INotifyPropertyChanged

Extension Methods

	Name	Description
	AddRangeT	Adds the elements of the specified collection to the end of the list. (Defined by CollectionExtensions)
	AddRangeT	Adds the elements of the specified collection to the end of the list. (Defined by CollectionExtensions)
	ContainsAnyT	Shortcut to test if any of the given items are contained in the specified object. (Defined by CollectionExtensions)
	ContainsAnyT	Shortcut to test if any of the given items are contained in the specified object. (Defined by CollectionExtensions)
	ExceptNullItemsT	Filters a sequence of values based on their nullness. (Defined by NullableExtensions)
	FindIndexT	Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the first occurrence within the entire IEnumerableT. (Defined by CollectionExtensions)
	ForEachT	Performs the specified action on each element of the collection. (Defined by CollectionExtensions)
	ForEachT	Performs the specified action on each element of the collection, providing also the index of the item. (Defined by CollectionExtensions)
	IndexOfT	Searches for the specified object and returns the zero-based index of the first occurrence within all items. (Defined by CollectionExtensions)
	IndexOfT	Searches for the specified object and returns the zero-based index of the first occurrence within all items. (Defined by CollectionExtensions)
	ObservableCastTTarget	Returns an observable collection of objects of type TTarget that mirrors the source collection. (Defined by ObservableExtensions)
	ObservableSelectT, TTarget	Projects each element of a sequence into a new form. (Defined by ObservableExtensions)
	ObservableSelectManyT, TTarget	Projects each element of a sequence to an IListT, flattens the resulting sequences into one sequence, and invokes a result selector function on each element therein. If the source is an observable collection, the resulting sequence will track the changes. (Defined by ObservableExtensions)
	ObservableWhereT	Returns an observable collection of objects of type T that contains all items of the source collection that pass the filter. See ObservableFilteredCollectionT for details. (Defined by ObservableExtensions)
	RemoveRangeT	Removes a range of elements from the list. (Defined by CollectionExtensions)
	RemoveWhereT	Removes the range of elements from the list that fulfill the condition. (Defined by CollectionExtensions)
	SafeCastT	Performs a cast from object to T, avoiding possible null violations if T is a value type. (Defined by ObjectExtensions)
	SynchronizeWithT	Synchronizes the items of the source list with the items of the target list. The order of the items is ignored. (Defined by CollectionExtensions)
	SynchronizeWithT	Synchronizes the items of the source list with the items of the target list. The order of the items is ignored. (Defined by CollectionExtensions)
	ToArrayT, TTarget	Creates an array from a ICollectionT. This method is faster than using Enumerable.Select(selector).ToArray() because the size of the target array is known in advance. (Defined by CollectionExtensions)
	TryAddRangeT	Adds the elements of the specified collection to the end of the list, but ignores all ArgumentException, e.g. when trying to add duplicate keys to a dictionary. (Defined by CollectionExtensions)
