Public Overridable Function GetStream (ordinal As Integer) As Stream



The zero-based column ordinal.


A stream.


The connection was dropped or closed during the data retrieval.


The data reader is closed during the data retrieval.


There is no data ready to be read (for example, the first Read() hasn't been called, or returned false).


The data reader tried to read a previously-read column in sequential mode.


There was an asynchronous operation in progress. This applies to all Get* methods when running in sequential mode, as they could be called while reading a stream.

The column index is out of range.

The specified column isn't a binary type that supports reading with a Stream.


GetStream only supports the retrieval of values that can be converted to byte arrays.
