The DataFileCollection type exposes the following members.

Properties

	Name	Description
	Count	Gets the number of objects in the referenced collection. (Inherited from SmoCollectionBase.)
	IsSynchronized	Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (Inherited from SmoCollectionBase.)
	Item[Int32]	Gets a DataFile object in the collection by index number.
	Item[String]	Gets a DataFile object in the collection by name.
	Parent	Gets the FileGroup object that is the parent of the DataFileCollection object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. (Inherited from SmoCollectionBase.)

Methods

	Name	Description
	Add	Adds a DataFile object to the DataFileCollection collection.
	AddExisting	Adds an object to the collection. (Inherited from AbstractCollectionBase.)
	Contains	Verifies whether the specified object exists in the collection. (Inherited from SimpleObjectCollectionBase.)
	CopyTo	Copies the collection objects to a one-dimensional array beginning at the index value specified.
	Equals	(Inherited from Object.)
	GetEnumerator	Returns an IEnumerator interface that allows you to iterate through the objects in the collection. (Inherited from SmoCollectionBase.)
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	ItemById	Extracts a member from the DataFileCollection collection using a system-defined, unique identifier.
	Refresh()	Refreshes the referenced collection. (Inherited from SmoCollectionBase.)
	Refresh(Boolean)	Refreshes the referenced collection with the option to refresh child objects of the referenced collection. (Inherited from SmoCollectionBase.)
	Remove(String)	Removes a DataFile object from the DataFileCollection collection by specifying the name of the data file.

	ToString	(Inherited from Object.)

Fields

	Name	Description
	initialized	This value supports the SMO infrastructure and is not intended to be used directly from your code. (Inherited from AbstractCollectionBase.)

Remarks

A DataFileCollection object can be used to gain access to a set of check constraints. You can use the Item property to return a specific DataFile object.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
