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 text type that supports reading with a TextReader.
Remarks
GetTextReader only supports the retrieval of values that can be converted to character arrays (strings).
