Description
Creates a new TParam instance and adds it to the TParams item array.
Use AddParameter to create a TParam in the TParams collection. The new TParam is placed at the end of the TParams item array.
AddParameter returns the new TParam item.
Note: To create, add, and initialize a new TParam to the list, you can use CreateParam instead of this method. AddParameter only creates and adds a TParam.
Note: Parameters for datasets that represent queries are only created by specifying parameters in the SQL statement. The TParam objects in such a dataset's Params property are created automatically when parameter tokens are added to the SQL statement.
