Valore restituito

Tipo: System.Boolean
A value of true if the enumerator was successfully advanced to the next record, or a value of false if the enumerator has passed the end of the result set.

Osservazioni

The default position of the IDataReader is prior to the first record. Therefore you must call Read to begin accessing any data.

While the data reader is in use, the associated connection is busy serving the IDataReader. This is the case until Close is called.
