Méthode	Description
Add ( string name, DataColumn primaryKeyColumn, DataColumn foreignKeyColumn ) : Constraint	Constructs a new with the specified parent and child columns and adds the constraint to the collection.
Add ( string name, DataColumn columns, bool primaryKey ) : Constraint	Constructs a new using the specified array of objects and adds it to the collection.
Add ( Constraint constraint ) : void	Adds the constraint to the collection.
AddRange ( Constraint constraints ) : void
CanRemove ( Constraint constraint ) : bool	Indicates if a can be removed.
Clear ( ) : void	Clears the collection of any objects.
Contains ( string name ) : bool	Indicates whether the , specified by name, exists in the collection.
CopyTo ( Constraint array, int index ) : void
IndexOf ( Constraint constraint ) : int	Returns the index of the specified .
IndexOf ( string constraintName ) : int	Returns the index of the , specified by name.
Remove ( Constraint constraint ) : void	Removes the specified from the collection.
Remove ( string name ) : void	Removes the constraint, specified by name, from the collection.
RemoveAt ( int index ) : void	Removes the constraint at the specified index from the collection.
this ( int index ) : Constraint	Gets the from the collection at the specified index.
this ( string name ) : Constraint	Gets the from the collection with the specified name.

Private Methods

Méthode	Description
Add ( Constraint constraint, bool addUniqueWhenAddingForeign ) : void
AddForeignKeyConstraint ( ForeignKeyConstraint constraint ) : void
AddUniqueConstraint ( UniqueConstraint constraint ) : void
ArrayAdd ( Constraint constraint ) : void	Adds the constraint to the constraints array.
ArrayRemove ( Constraint constraint ) : void
AssignName ( ) : string	Creates a new default name.
AutoGenerated ( Constraint constraint ) : bool
BaseAdd ( Constraint constraint ) : void	Does verification on the constraint and it's name. An ArgumentNullException is thrown if this constraint is null. An ArgumentException is thrown if this constraint already belongs to this collection, belongs to another collection. A DuplicateNameException is thrown if this collection already has a constraint with the same name (case insensitive).
BaseGroupSwitch ( Constraint oldArray, int oldLength, Constraint newArray, int newLength ) : void	BaseGroupSwitch will intelligently remove and add tables from the collection.
BaseRemove ( Constraint constraint ) : void	Does verification on the constraint and it's name. An ArgumentNullException is thrown if this constraint is null. An ArgumentException is thrown if this constraint doesn't belong to this collection or if this constraint is part of a relationship.
CanRemove ( Constraint constraint, bool fThrowException ) : bool
CompareArrays ( DataColumn a1, DataColumn a2 ) : bool
ConstraintCollection ( DataTable table ) : System.Diagnostics	ConstraintCollection constructor. Used only by DataTable.
Contains ( string name, bool caseSensitive ) : bool
FindConstraint ( Constraint constraint ) : Constraint	Returns a matching constriant object.
FindForeignKeyConstraint ( DataColumn parentColumns, DataColumn childColumns ) : ForeignKeyConstraint	Returns a matching constriant object.
FindKeyConstraint ( DataColumn columns ) : UniqueConstraint	Returns a matching constriant object.
FinishInitConstraints ( ) : void
InternalIndexOf ( string constraintName ) : int
MakeName ( int index ) : string	Makes a default name with the given index. e.g. Constraint1, Constraint2, ... Constrainti
OnCollectionChanged ( CollectionChangeEventArgs ccevent ) : void	Raises the event.
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 Constraint.ConstraintName 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 Constraint.ConstraintName property. If the name is equivalent to the last proposed default name, we walk backwards to find the next proper default name to use.
