The zero-based column ordinal.

Returns

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.
