Exceptions

The connection drops or is closed during the data retrieval.

The DbDataReader 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).

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 returned type was not one of the types below:

  • char

  • nchar

  • ntext

  • nvarchar

  • text

  • varchar

Remarks

GetTextReader only supports the retrieval of values that can be converted to character arrays (strings).
