Methods

	Name	Description
	Add	Add an item to the end of this collection. (Overrides CollectionOfvariant Add(Object).)
	AddRange	Adds the elements of the specified collection to the end of the collection.
	Clear	Remove all items from this collection. (Overrides CollectionOfvariant Clear .)
	Contains	Determine whether an item is in this collection. (Overrides CollectionOfvariant Contains(Object).)
	CopyTo	Copies all the elements of the collection to the specified one-dimensional array starting at the specified destination array index. The index is specified as a 32-bit integer. (Overrides CollectionOfvariant CopyTo( Object , Int32).)
	Equals	Compares the equality of this object with another. (Overrides ChangedEventShareableBase Equals(Object).)
	GetEnumerator	Returns an IEnumerator for the collection. (Overrides CollectionOfvariant GetEnumerator .)
	GetHashCode	Returns the hash code of this object. (Overrides ChangedEventShareableBase GetHashCode .)
	GetItem	Get the item at the specified index. (Overrides CollectionOfvariant GetItem(Int32).)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetTypeMeta	Get the TypeMeta that describes the type of this object. (Overrides CollectionOfvariant GetTypeMeta .)
	IndexOf	Find the first item in this collection that matches the supplied item, and return its index. (Overrides CollectionOfvariant IndexOf(Object).)
	Insert	Insert the given item at the specified index. (Overrides CollectionOfvariant Insert(Int32, Object).)
	Move	Move the selected item to a new index in this collection. (Overrides CollectionOfvariant Move(Int32, Int32).)
	Remove	Remove the specified item from this collection. (Overrides CollectionOfvariant Remove(Object).)
	RemoveAt	Remove the item at the specified index. (Overrides CollectionOfvariant RemoveAt(Int32).)
	Reserve	Set the collection capacity be at least the specified number of items. If minimumCapacity is greater than the current collection capacity, this method will cause the collection to reallocate its storage, increasing its capacity to at least minimumCapacity. Attempts to set capacity to a value less than or equal to the current value are ignored. (Overrides CollectionOfvariant Reserve(Int64).)
	ResumeAndRaiseChangedEvent	Re-enables raising of the ChangedEvent after SuspendChangedEvent has been called, and raises the ChangedEvent if the ChangedEventSuspended count is reduced to zero and any changes were made while events were suspended. Must be called once for each call to SuspendChangedEvent. (Overrides CollectionOfvariant ResumeAndRaiseChangedEvent .)
	setItem	Replace the element at the specified index. (Overrides CollectionOfvariant setItem(Int32, Object).)
	SuspendChangedEvent	Temporarily suspends the raising of the ChangedEvent. May be called more than once, and a corresponding call to ResumeAndRaiseChangedEvent must be made for each call to SuspendChangedEvent. (Overrides CollectionOfvariant SuspendChangedEvent .)
	ToString	Returns a human readable string that represents the object. (Overrides CollectionOfvariant ToString .)

Operators

	Inequality	Compares the inequality of two VariantCollection objects.

Properties

	Name	Description
	Capacity	Get the capacity of this collection. This is the maximum number of items that may be stored in this collection without reallocation. Capacity is increased automatically as needed to hold added items. (Overrides CollectionOfvariant Capacity.)
	ChangedEventSuspended	Indicates if raising the ChangedEvent has been suspended. (Overrides CollectionOfvariant ChangedEventSuspended.)
	Count	Get the number of elements contained in this collection. (Overrides CollectionOfvariant Count.)
	Handle	(Overrides CollectionOfvariant Handle.)
	IsReadOnly	Get whether or not this collection is read-only. (Overrides CollectionOfvariant IsReadOnly.)
	Item	(Overrides CollectionOfvariant Item Int32 .)

Events

	Name	Description
	Changed	The actual event. (Overrides CollectionOfvariant Changed.)
	Cleared	Raised after the collection is cleared. (Overrides CollectionOfvariant Cleared.)
	Clearing	Raised before the collection is cleared. (Overrides CollectionOfvariant Clearing.)
	InsertedItem	Raised after an item is inserted. (Overrides CollectionOfvariant InsertedItem.)
	InsertingItem	Raised before an item is inserted. (Overrides CollectionOfvariant InsertingItem.)
	MovedItem	Raised after an item is moved to a new index. (Overrides CollectionOfvariant MovedItem.)
	MovingItem	Raised before an item is moved to a new index. (Overrides CollectionOfvariant MovingItem.)
	RemovedItem	Raised after an item is removed. (Overrides CollectionOfvariant RemovedItem.)
	RemovingItem	Raised before an item is removed. (Overrides CollectionOfvariant RemovingItem.)
	ReplacedItem	Raised after an item is replaced. (Overrides CollectionOfvariant ReplacedItem.)
	ReplacingItem	Raised before an item is replaced. (Overrides CollectionOfvariant ReplacingItem.)
