Add ( DataColumn parentColumns, DataColumn childColumns ) : DataRelation	Creates a relation given the parameters and adds it to the collection. The name is defaulted. An ArgumentException is thrown if this relation already belongs to this collection or belongs to another collection. An InvalidConstraintException is thrown if the relation can't be created based on the parameters. The CollectionChanged event is fired if it succeeds.
Add ( string name, DataColumn parentColumns, DataColumn childColumns ) : DataRelation	Creates a with the specified name, parent columns, child columns, and adds it to the collection.
Add ( string name, DataColumn parentColumns, DataColumn childColumns, bool createConstraints ) : DataRelation	Creates a relation given the parameters and adds it to the collection. An ArgumentNullException is thrown if this relation is null. An ArgumentException is thrown if this relation already belongs to this collection, belongs to another collection, or if this collection already has a relation with the same name (case insensitive). An InvalidRelationException is thrown if the relation can't be created based on the parameters. The CollectionChanged event is fired if it succeeds.

AddRange ( DataRelation relations ) : void
CanRemove ( DataRelation relation ) : bool	Verifies if a given relation can be removed from the collection.
Clear ( ) : void	Clears the collection of any relations.
Contains ( string name ) : bool	Returns true if this collection has a relation with the given name (case insensitive), false otherwise.
CopyTo ( DataRelation array, int index ) : void
IndexOf ( DataRelation relation ) : int	Returns the index of a specified .
IndexOf ( string relationName ) : int	Returns the index of the relation with the given name (case insensitive), or -1 if the relation doesn't exist in the collection.

AssignName ( ) : string	Creates a new default name.
InternalIndexOf ( string name ) : int
MakeName ( int index ) : string	Makes a default name with the given index. e.g. Relation1, Relation2, ... Relationi
RegisterName ( string name ) : void	Registers this name as being used in the collection. Will throw an ArgumentException if the name is already being used. Called by Add, All property, and Relation.RelationName property. if the name is equivalent to the next default name to hand out, we increment our defaultNameIndex.
UnregisterName ( string name ) : void	Unregisters this name as no longer being used in the collection. Called by Remove, All property, and Relation.RelationName property. If the name is equivalent to the last proposed default name, we walk backwards to find the next proper default name to use.
