ProviderConnectionPointCollection Class

.NET Framework (current version)

Contains a collection of all ProviderConnectionPoint objects associated with a particular WebPart or server control acting as a provider in a connection. This class cannot be inherited.

public ref class ProviderConnectionPointCollection sealed : ReadOnlyCollectionBase

Constructors

	Name	Description
	ProviderConnectionPointCollection()	Initializes an empty new instance of the ProviderConnectionPointCollection class.
	ProviderConnectionPointCollection(ICollection^)	Initializes a new instance of the ProviderConnectionPointCollection class using the specified collection of provider connection points.

Properties

	Name	Description
	Count	Gets the number of elements contained in the ReadOnlyCollectionBase instance.(Inherited from ReadOnlyCollectionBase.)
	Default	Gets the default connection point from the collection of provider connection points associated with a particular control.
	Item[Int32]	Gets a member of the collection based on its position in the collection.
	Item[String^]	Gets a member of the collection based on a unique string identifier.

Methods

	Name	Description
	Contains(ProviderConnectionPoint^)	Returns a value indicating whether a particular ProviderConnectionPoint object exists in the collection.
	CopyTo(array<ProviderConnectionPoint^>^, Int32)	Copies the collection to an array of ProviderConnectionPoint objects.
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	GetEnumerator()	Returns an enumerator that iterates through the ReadOnlyCollectionBase instance.(Inherited from ReadOnlyCollectionBase.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	IndexOf(ProviderConnectionPoint^)	Returns the position of a particular ProviderConnectionPoint object within a collection.
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Explicit Interface Implementations

	Name	Description
	ICollection::CopyTo(Array^, Int32)	Copies the entire ReadOnlyCollectionBase to a compatible one-dimensional Array, starting at the specified index of the target array.(Inherited from ReadOnlyCollectionBase.)
	ICollection::IsSynchronized	Gets a value indicating whether access to a ReadOnlyCollectionBase object is synchronized (thread safe).(Inherited from ReadOnlyCollectionBase.)
	ICollection::SyncRoot	Gets an object that can be used to synchronize access to a ReadOnlyCollectionBase object.(Inherited from ReadOnlyCollectionBase.)

Extension Methods

	Name	Description
	AsParallel()	Overloaded. Enables parallelization of a query.(Defined by ParallelEnumerable.)
	AsQueryable()	Overloaded. Converts an IEnumerable to an IQueryable.(Defined by Queryable.)
	Cast<TResult>()	Casts the elements of an IEnumerable to the specified type.(Defined by Enumerable.)
	OfType<TResult>()	Filters the elements of an IEnumerable based on a specified type.(Defined by Enumerable.)

A WebPart or server control acting as a provider in a Web Parts connection can have multiple provider connection points. One ProviderConnectionPoint object in a provider acts as the connection point for any given connection, serving as the primary interface instance to pass to one or more consumers.

The ProviderConnectionPointCollection class contains the collection of all the connection points associated with a provider control. Several classes in the Web Parts control set need to determine what connection points are available on a provider control, and when they do they typically call the GetProviderConnectionPoints method, which returns a ProviderConnectionPointCollection collection.

Note
This class inherits from the ReadOnlyCollectionBase class, making this collection a strongly typed, non-generic, read-only collection. You cannot add or remove members after an instance has been created.
