The MappingItemCollection type exposes the following members.

Properties

	Name	Description
	Count	Gets the number of elements contained in the ReadOnlyCollection(Of T) instance. (Inherited from ReadOnlyCollection(Of T).)
	DataSpace	Gets the data model associated with this item collection. (Inherited from ItemCollection.)
	IsReadOnly	Gets a value indicating whether this collection is read-only. (Inherited from ReadOnlyMetadataCollection(Of T).)
	Item(Int32)	Gets the element at the specified index. (Inherited from ReadOnlyCollection(Of T).)
	Item(String)	Gets an item from this collection by using the specified identity. (Inherited from ReadOnlyMetadataCollection(Of T).)
	Items	Returns the IList(Of T) that the ReadOnlyCollection(Of T) wraps. (Inherited from ReadOnlyCollection(Of T).)

Methods

	Name	Description
	Contains(T)	Determines whether an element is in the ReadOnlyCollection(Of T). (Inherited from ReadOnlyCollection(Of T).)
	Contains(String)	Determines whether the collection contains an item with the specified identity. (Inherited from ReadOnlyMetadataCollection(Of T).)
	CopyTo	Copies the entire ReadOnlyCollection(Of T) to a compatible one-dimensional Array, starting at the specified index of the target array. (Inherited from ReadOnlyCollection(Of T).)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetEntityContainer(String)	Returns an EntityContainer object by using the specified entity container name. (Inherited from ItemCollection.)
	GetEntityContainer(String, Boolean)	Returns an EntityContainer object by using the specified entity container name. (Inherited from ItemCollection.)
	GetEnumerator	Returns an enumerator that can iterate through this collection. (Inherited from ReadOnlyMetadataCollection(Of T).)
	GetFunctions(String)	Returns all the overloads of the functions by using the specified name from this item collection. (Inherited from ItemCollection.)
	GetFunctions(String, Boolean)	Returns all the overloads of the functions by using the specified name from this item collection. (Inherited from ItemCollection.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetItem(Of T)(String)	Returns a strongly typed GlobalItem object by using the specified identity. (Inherited from ItemCollection.)
	GetItem(Of T)(String, Boolean)	Returns a strongly typed GlobalItem object by using the specified identity with either case-sensitive or case-insensitive search. (Inherited from ItemCollection.)
	GetItems(Of T)	Returns all the items of the specified type from this item collection. (Inherited from ItemCollection.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetType(String, String)	Returns an EdmType object by using the specified type name and the namespace name in this item collection. (Inherited from ItemCollection.)
	GetType(String, String, Boolean)	Returns an EdmType object by using the specified type name and the namespace name from this item collection. (Inherited from ItemCollection.)
	GetValue	Retrieves an item from this collection by using the specified identity. (Inherited from ReadOnlyMetadataCollection(Of T).)
	IndexOf	Returns the index of the specified value in this collection. (Inherited from ReadOnlyMetadataCollection(Of T).)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	TryGetEntityContainer(String, EntityContainer)	Returns an EntityContainer object by using the specified entity container name. If there is no entity container, the output parameter contains null; otherwise, it contains the first entity container. (Inherited from ItemCollection.)
	TryGetEntityContainer(String, Boolean, EntityContainer)	Returns an EntityContainer object by using the specified entity container name. If there is no entity container, this output parameter contains null; otherwise, it contains the first entity container. (Inherited from ItemCollection.)
	TryGetItem(Of T)(String, T)	Returns a strongly typed GlobalItem object by using the specified identity from this item collection. (Inherited from ItemCollection.)
	TryGetItem(Of T)(String, Boolean, T)	Returns a strongly typed GlobalItem object by using the specified identity from this item collection. (Inherited from ItemCollection.)
	TryGetType(String, String, EdmType)	Returns an EdmType object by using the specified type name and the namespace name from this item collection. (Inherited from ItemCollection.)
	TryGetType(String, String, Boolean, EdmType)	Returns an EdmType object by using the specified type name and the namespace name from this item collection. (Inherited from ItemCollection.)
	TryGetValue	Retrieves an item from this collection by using the specified identity. (Inherited from ReadOnlyMetadataCollection(Of T).)
