	Count	Gets the number of objects in the referenced collection. (hérité de SmoCollectionBase.)
	IsSynchronized	Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (hérité de SmoCollectionBase.)
	Item[ ( [ ( Int32] ) ] )	Gets a Column object in the collection by index number.
	Item[ ( [ ( String] ) ] )	Gets a Column object in the collection by name.
	Parent	Gets the SqlSmoObject object that is the parent of the ColumnCollection object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. (hérité de SmoCollectionBase.)
