Add ( DataTable table ) : void	Adds the specified table to the collection.
AddRange ( DataTable tables ) : void
CanRemove ( DataTable table ) : bool	Verifies if a given table can be removed from the collection.
Clear ( ) : void	Clears the collection of any tables.
Contains ( string name ) : bool	Checks if a table, specified by name, exists in the collection.
Contains ( string name, string tableNamespace ) : bool
CopyTo ( DataTable array, int index ) : void
IndexOf ( DataTable table ) : int	Returns the index of a specified .
IndexOf ( string tableName ) : int	Returns the index of the table with the given name (case insensitive), or -1 if the table doesn't exist in the collection.

Private Methods

Method	Description
ArrayAdd ( DataTable table ) : void
AssignName ( ) : string	Creates a new default name.
BaseAdd ( DataTable table ) : void	Does verification on the table and it's name, and points the table at the dataSet that owns this collection. An ArgumentNullException is thrown if this table is null. An ArgumentException is thrown if this table already belongs to this collection, belongs to another collection. A DuplicateNameException is thrown if this collection already has a table with the same name (case insensitive).
BaseGroupSwitch ( DataTable oldArray, int oldLength, DataTable newArray, int newLength ) : void	BaseGroupSwitch will intelligently remove and add tables from the collection.
BaseRemove ( DataTable table ) : void	Does verification on the table and it's name, and clears the table's dataSet pointer. An ArgumentNullException is thrown if this table is null. An ArgumentException is thrown if this table doesn't belong to this collection or if this table is part of a relationship.
CanRemove ( DataTable table, bool fThrowException ) : bool
Contains ( string name, bool caseSensitive ) : bool
Contains ( string name, string tableNamespace, bool checkProperty, bool caseSensitive ) : bool
DataTableCollection ( DataSet dataSet ) : System.Diagnostics	DataTableCollection constructor. Used only by DataSet.
FinishInitCollection ( ) : void

IndexOf ( string tableName, string tableNamespace, bool chekforNull ) : int
InternalIndexOf ( string tableName ) : int
InternalIndexOf ( string tableName, string tableNamespace ) : int
MakeName ( int index ) : string	Makes a default name with the given index. e.g. Table1, Table2, ... Tablei
OnCollectionChanged ( CollectionChangeEventArgs ccevent ) : void	Raises the event.
OnCollectionChanging ( CollectionChangeEventArgs ccevent ) : void
RegisterName ( string name, string tbNamespace ) : 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 Table.TableName property. if the name is equivalent to the next default name to hand out, we increment our defaultNameIndex.
ReplaceFromInference ( List tableList ) : void
UnregisterName ( string name ) : void	Unregisters this name as no longer being used in the collection. Called by Remove, All property, and Table.TableName property. If the name is equivalent to the last proposed default name, we walk backwards to find the next proper default name to use.
