The zero-based column ordinal.

A stream.
Exceptions
The connection was dropped or closed during the data retrieval.
-or-
The data reader is closed during the data retrieval.
-or-
There is no data ready to be read (for example, the first Read() hasn't been called, or returned false).
-or-
The data reader tried to read a previously-read column in sequential mode.
-or-
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 specified column isn't a binary type that supports reading with a Stream.
Remarks
GetStream only supports the retrieval of values that can be converted to byte arrays.
