CollectionBase(T) Class

CollectionBaseT Class

CollectionBase is a base class that can be used to more easily implement the generic ICollection<T> and non-generic ICollection interfaces.

Syntax

C++

Copy

[SerializableAttribute]
public abstract class CollectionBase<T> : ICollection<T>, 
	IEnumerable<T>, ICollection, IEnumerable

[SerializableAttribute]
generic<typename T>
public ref class CollectionBase abstract : ICollection<T>, 
	IEnumerable<T>, ICollection, IEnumerable

Type Parameters

T: The item type of the collection.

The CollectionBaseT type exposes the following members.

Constructors

	Name	Description
	CollectionBaseT	Initializes a new instance of the CollectionBaseT class

Methods

	Name	Description
	Add	Must be overridden to allow adding items to this collection.
	AsReadOnly	Provides a read-only view of this collection. The returned ICollection<T> provides a view of the collection that prevents modifications to the collection. Use the method to provide access to the collection without allowing changes. Since the returned object is just a view, changes to the collection will be reflected in the view.
	Clear	Must be overridden to allow clearing this collection.
	Contains	Determines if the collection contains a particular item. This default implementation iterates all of the items in the collection via GetEnumerator, testing each item against item using IComparable<T>.Equals or Object.Equals.
	ConvertAllTOutput	Convert this collection of items by applying a delegate to each item in the collection. The resulting enumeration contains the result of applying converter to each item in this collection, in order.
	CopyTo	Copies all the items in the collection into an array. Implemented by using the enumerator returned from GetEnumerator to get all the items and copy them to the provided array.
	CountWhere	Counts the number of items in the collection that satisfy the condition defined by predicate.
	Equals	(Inherited from Object.)
	Exists	Determines if the collection contains any item that satisfies the condition defined by predicate.
	Finalize	(Inherited from Object.)
	FindAll	Enumerates the items in the collection that satisfy the condition defined by predicate.
	ForEach	Performs the specified action on each item in this collection.
	GetEnumerator	Must be overridden to enumerate all the members of the collection.
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	MemberwiseClone	(Inherited from Object.)
	Remove	Must be overridden to allow removing items from this collection.
	RemoveAll	Removes all the items in the collection that satisfy the condition defined by predicate.
	ToArray	Creates an array of the correct size, and copies all the items in the collection into the array, by calling CopyTo.
	ToString	Shows the string representation of the collection. The string representation contains a list of the items in the collection. Contained collections (except string) are expanded recursively. (Overrides ObjectToString.)
	TrueForAll	Determines if all of the items in the collection satisfy the condition defined by predicate.

Properties

	Name	Description
	Count	Must be overridden to provide the number of items in the collection.

Remarks

To use CollectionBase as a base class, the derived class must override the Count, GetEnumerator, Add, Clear, and Remove methods.

ICollection<T>.Contains need not be implemented by the derived class, but it should be strongly considered, because the CollectionBase implementation may not be very efficient.
